TRANSCRIPT
1
Food safety has become an issue of special importance for the retail food
industry. There are many opportunities for food to be contaminated between production
and consumption. Food can be contaminated at the farm, ranch, orchard, or in the sea.
Food also can be contaminated at food processing plants and during transport to food
establishments. Finally, food can be contaminated during the last stages of production,
at retail establishments, and by consumers in their homes. Food safety is especially
critical in retail food establishments because this maybe the last opportunity to control or
eliminate the hazards that might contaminate food and cause food borne illnesses.
Background of the Study
The researchers will conduct this study in the square canteen of De LaSalle
University Dasmariñas. The possible respondents will be the students of DLSU-D.
De La Salle University-Dasmariñas is a member institution of De La Salle
Philippines located in Dasmariñas, Cavite. It was established on July 18, 1977 as a
private nonsectarian tertiary school named General Emilio Aguinaldo College-
Cavite and managed by the YamanLahi Foundation. In 1987, ownership and
management were transferred to Frère Bénilde Romançon Educational Foundation Inc.,
a sister corporation of De La Salle University. It became a Catholic institution under the
name De La Salle University-Emilio Aguinaldo College. In 1992, the name DLSU-EAC
was changed to De La Salle University-Aguinaldo. In 1997 the institution was renamed
again as De La Salle University-Dasmariñas to avoid confusion with the Emilio
Aguinaldo College in Cavite.

In De LaSalle University Dasmariñas there is a lot of food chain. If we said a food
chain one thing comes first in our mind, if the food is clean. It’s not just about the taste
of the food, or the space in the food establishments, the most important question to
consider is “How clean your food is?”
Food sanitation is a series of protocols which are designed to prevent the
contamination of food, keeping it safe to eat. Numerous nations have specific laws in
place concerning food sanitation, along with lengthy lists of recommendations
from public health agencies.
This study wants to know the practices done by the food establishments as
observed and perceived by the students of De LaSalle University- Dasmariñas as the
relation common food borne illness that the students may commonly experience in
relation to the food that they eat in the University food square.
Theoretical Framework
These hazards that could cause human illness, injury or death are of three types:
biological hazards, such as food borne microbial pathogens, viruses, parasites and
fungi, chemical hazards such as toxins, allergens, heavy metals, not allowed food
additives, antibiotic and pesticide residues; and physical hazards such as foreign
objects like glass.
This study is Republic Act No. 7394 or most commonly known as The Consumer Act of
the Philippines states that it is the policy of the State to protect the interests of the
3
consumer, promote his general welfare and to establish standards of conduct for
business and industry. Towards this end, the State shall implement measures to
achieve the a) protection against hazards to health and safety; b) protection against
deceptive, unfair and unconscionable sales acts and practices; c) provision of
information and education to facilitate sound choice and the proper exercise of rights by
the consumer; d) provision of adequate rights and means of redress; and e)
involvement of consumer representatives in the formulation of social and economic
policies.

Statement of the Problem
The main objective of this study is to determine Food Sanitation practices among
food chains in De La Salle University- Dasmariñas. The target respondents of the
researchers will be the students of DLSU-D.
Specifically, this study will answer the following:
1. What is the food sanitation practice done by food handlers on the square
canteen of De La Salle University- Dasmariñas to ensure food safety?
2. What are the different illnesses that human can get from mishandled food?
Scope and Delimitation
The scope and limitation of the study were about the stated problem of the
research, these were the improper food preparation of the establishment and the
improper food storage practices done by the establishments and about the proper
hygiene of the employees. The student respondents will be the students of De LaSalle
University- Dasmariñas.
This study will focus on awareness of Food Sanitation on selected food chains
inside De La Salle University- Dasmariñas. The researchers will select among the food
5
chains whose willing to give information about Food Sanitation of their food
establishment. Food handlers will answer a questionnaire regarding the topic. Also, the
researchers will construct a survey to selected students on how aware are they on food
sanitation and what they can say about the food sanitation on different food chains
insideDe La Salle University- Dasmariñas.
Significance of the Study
This study would help the following groups of people:
Food establishment inside the campus. This research would provide basic
awareness and essential methods of food handling and techniques to avoid the food
borne illness. In addition, the findings that will gather in this research will help the
establishment to gain more profit by providing more safe meals.
Employees of the participating establishment. This study would give the
employees an awareness and the evaluation to their selves whether they are doing
good or not in terms of proper food handling.
Customer of the participating establishment. This study would provide
knowledge and also the basic awareness of proper things that the food establishments
must know and consider.
Student taking up Hotel and Restaurant Management. This study is
significant for them because in the future, these student of Hotel and Restaurant
Management will deal to this kind of situation when the time they’re handling their own
businesses and also to improve the standards of operation.
6
Future researchers. This study offers knowledge to the future researchers about
the current situation in food handling today.
Definition of Terms
As used in the study, the following terms are defined:
Contamination.The act or process of contaminating or the state of being contaminated
Food.Is any substance consumed to provide nutritional support for the body. It is
usually of plant or animal origin, and contains essential nutrients, such
as carbohydrates, fats, proteins, vitamins, or minerals.
Biological hazards. Also known as biohazards, refer to biological substances that pose
a threat to the health of living organisms, primarily that of humans.
Chemicalhazards. Any hazard that results from the accidental, deliberate or potential
release of a noxious substance into the environment.
DLSU-D. De LaSalle University- Dasmariñas
Foodborne illness.Is any illness resulting from the consumption of
contaminated, pathogenic bacteria, viruses, or parasites that contaminate food.
Food Chain/ Food Establishment.Is an operation that stores, prepares, packages,
serves, or otherwise provides food for human consumption such as: a food service
establishment, retail food store, satellite or catered feeding location.
Hazard.Is a situation in the workplace that has the potential to harm the health and
safety of people or to damage plant and equipment. The situation could involve a task,
7
chemical or equipment used. Hazard management is a continuous process that can be
used to improve the health and safety of all workplaces.
Physical Hazard.There is scientifically valid evidence that it is a combustible liquid, a
compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric,
unstable (reactive), or water-reactive.
Sanitation.Comes from the word sanitas which means “health”.Sanitation is
the hygienic means of promoting health through prevention of human contact with
the hazards of wastes.

Food can transmit disease from person to person as well as serve as a growth
medium for bacteria that can cause food poisoning. Debates on genetic food safety
include such issues as impact of genetically modified food on health of further
generations and genetic pollution of environment, which can destroy natural biological
diversity. In developed countries there are intricate standards for food preparation,
whereas in lesser developed countries the main issue is simply the availability of
adequate safe water, which is usually a critical item. In theory food poisoning is 100%
preventable. The five key principles of food hygiene, according to WHO, are: (1.)
Prevent contaminating food with pathogens spreading from people, pets, and pests; (2.)
Separate raw and cooked foods to prevent contaminating the cooked foods; (3.) Cook
foods for the appropriate length of time and at the appropriate temperature to kill
pathogens. (5.) Store food at the proper temperature. (6.) Do use safe water and
cooked materials (Retrieved from http://en.wikipedia.org/wiki/Food_safety on July
2012).
The concept of safe and wholesome food encompasses many diverse elements.
From a nutritional aspect, it is food that contains the nutrients humans need and that
helps prevent long-term chronic disease, promoting health into old age. From a food
safety aspect, it is food that is free not only from toxins, pesticides, and chemical and
physical contaminants, but also from microbiological pathogens such as bacteria and
viruses that can cause illness. This book is concerned with the food safety aspect of
food, leaving the diet and nutritional properties of food for experts in nutrition (Roberts,
2001).

Sickness affects most people at one time or another. It is caused by eating food
that is contaminated with pathogens such as bacteria, viruses, or parasites. At least four
factors are necessary for foodborne illness to occur: (1) a pathogen; (2) a food vehicle;
(3) conditions that allow the pathogen to survive, reproduce, or produce a toxin; and (4)
a susceptible person who ingests enough of the pathogen or its toxin to cause illness.
The symptoms often are similar to those associated with the flu-nausea, vomiting,
diarrhea, abdominal pain, fever, headache. Most people have experienced foodborne
illness, even though they might not recognize it as such, instead blaming it on the
“stomach flu” or “24-hour bug.” Symptoms usually disappear within a few days, but in
some cases there can be more long-lasting effects such as joint inflammation or kidney
failure. In the most severe cases people die from foodborne illness. Every year more
than 5,000 Americans die from eating contaminated food (Mead, 1999).
It is difficult to trace a bout of foodborne illness back to a particular food because
illness can occur anywhere from an hour to several days, or even weeks, after eating
the contaminated food. Epidemiologists faced with tracing a foodborne illness outbreak
may have to interview dozens of people, asking them to recall everything they ate for
the past week. It is difficult for people to remember everything they ate yesterday, much
less one week ago. Further complicating the picture is that one person may eat the
contaminated food and not become ill, while someone else in a higher-risk group does.
In 81 percent of foodborne illnesses the cause remains unknown(Mead, 1999).
10
In addition to constant changes in food production and substantial growth in the
number of food facilities (the number regulated by the U.S. Food and Drug
Administration [FDA] grew by 10 percent between 2003 and 2007 [GAO, 2008), the
food and agriculture sector has experienced widespread integration and consolidation in
recent years. For example, the consolidation of supermarkets has changed the retail
grocery landscape in the United States, leading to the dominance of the industry by a
small number of large companies. Apart from consequences for the market share of
small retailers, the greater dependence of manufacturers on this limited number of
retailers for sales volume gives these companies significant leverage to bargain for
lower prices and demand safety standards. The result has been an increased tendency
to establish private standards, which has changed the enterprise of food safety (Henson
and Humphrey, 2009).
While food producers, processors, and retailers have the primary responsibility
for the safety of the food they produce, food preparers also play an important role in
preventing foodborne illness. Accordingly, several groups have developed educational
messages aimed at teaching safe food-handling behaviors to consumers and other food
preparers. The Clean, Separate, Cook, Chill approach, for example, is focused primarily
on consumers in the home. However, this initiative has proven to be largely ineffective
(Anderson et al., 2004).
Several studies have found that, although self-reported use of safe food-handling
practices has increased, consumers and other food preparers do not always follow
these practices (Redmond and Griffith, 2003; Howells et al., 2008; Abbot et al., 2009).
Further, the International Food Information Council Foundation found that many
11
consumers fail to use some important food safety practices; for example, just 50 and 25
percent of consumers, respectively, use a different or freshly cleaned cutting board for
each type of food and check the doneness of meat and poultry items with a food
thermometer (IFICF, 2009).
Several factors have been identified as affecting the adoption of safe food-
handling practices, including attitudes, lack of motivation, sociodemographic factors,
and cultural beliefs (Medeiros et al., 2004; Patil et al., 2005; Pilling et al., 2008). In
addition, the media often promote poor food-handling practices during on-air cooking
demonstrations and frequently give misinformation on the subject (Mathiasen et al.,
2004).
The decline of home economics classes in schools, coupled with the increasing
trend to eat out, further contributes to the lack of food safety knowledge. In addition, few
medical providers diagnose and report foodborne illness, and fewer yet discuss safe
food-handling practices with their patients (Wong et al., 2004; Henao et al., 2005).
If the primary objective of the food safety system is to reduce the burden of
disease, success requires risk-based resource allocation. The food safety system must
make the best possible use of its resources to reduce the disease burden. This means
focusing government effort on the greatest risks and the greatest opportunities to
reduce risk, wherever they may arise. It means adopting the interventions—presumably
some combination of research, regulation, and education that will yield the greatest
reduction in illness (Taylor, 2002).
A survey found that 25% of U.S. government inspectors and scientists surveyed
have experienced during the past year corporate interests forcing their food safety
12
agency to withdraw or to modify agency policy or action that protects consumers.
Scientists have observed that management undercuts field inspectors who stand up for
food safety against industry pressure. According to Dr. Dean Wyatt, a USDA
veterinarian who oversees federal slaughter house inspectors, "Upper level
management does not adequately support field inspectors and the actions they take to
protect the food supply. Not only is there lack of support, but there's outright obstruction,
retaliation and abuse of power."In addition to the US Food and Drug Administration,
several states that are major producers of fresh fruits and vegetables (including
California, Arizona and Florida) have their own state programs to test produce
for pesticide residues. Restaurants and other retail food establishments fall under state
law and are regulated by state or local health departments. Typically these regulations
require official inspections of specific design features, best food-handling practices, and
certification of food handlers.[25] In some places a letter grade or numerical score must
be prominently posted following each inspection.[26] In some localities, inspection
deficiencies and remedial action are posted on the Internet (retrieved from
http://en.wikipedia.org/wiki/Food_safety on July 2012).
Foodborne disease outbreaks in the United States are caused by the following
(with percent of frequency):Bacteria- 66%, Chemicals- 25%, Viruses- 5%and Parasites-
4%. Chemicals are usually in solution and cannot be seen. Parasites involved in most
outbreaks are very small and cannot be seen with the unaided eye. Bacteria and
viruses are extremely microscopic. It would take millions of bacteria to produce a colony
the size of the period at the end of this sentence. This amount of bacteria is more than
enough to cause many people to become seriously ill.Bacteria are everywhere in our
13
environment. Most are harmless. Some are beneficial and used to make foods, such as
cheese. Others are spoilage organisms that sour and rot our food. A few become a
threat to our health when they grow and reproduce. Sources of these bacteria areas
follows: soil, water, air, dust, edible plants and plant products, animals and animal
products, intestinal tract of man and animals, employee's hands and contaminated food
utensils and equipment.A common misconception is that food is free of bacteria that
cause foodborne diseases when it reaches the establishment or after processing. The
following information suggests otherwise.Concentrations of two types of foodborne
disease organisms were found in 28% of pork sausage. Fresh ground beef in a recent
study was found to contain three types of foodborne disease organisms.Poultry
represents an important source of foodborne disease organisms. In one study90% of
the market-ready chicken and turkey were contaminated with foodborne disease
bacteria. In another study more than half of the poultry samples harbored two types of
foodborne disease bacteria. The incidence of foodborne disease organisms in shellfish
depends greatly upon the quality of water from which animals are harvested and
handled. In one study, 47% of clams, mussels, and oysters were positive for enter
viruses. In another study, 33% of the seafood tested positive for organisms of
salmonellosis.Milk is of little risk because it is pasteurized. However, post pasteurization
contamination and adding ingredients to milk increases potential for outbreaks. Twenty
percent of some cheeses are contaminated with disease bacteria. Unpasteurized dairy
products present greater risk. Raw milk tested positive for a common disease organism
in 48% of the samples taken.Dry Products. In a survey of dry sauce and gravy mixes,
soup mixes, spaghetti sauce mixes, and cheese sauce mixes, 18% were contaminated
14
with foodborne disease organisms.Grains and granary products are commonly
contaminated with bacteria. In one study, 100% of raw rice was contaminated with a
foodborne disease organism.Thesurface of freshly baked bread products is practically
free of microorganisms, but they are subject to contamination from the air during cooling
and during handling. Filled pastries present much greater risk.Raw vegetables are
commonly contaminated with bacteria from the soil. For example, botulism causing
bacteria were found in 12% of frozen spinach in one study. In another study, 46% of raw
vegetables were contaminated with another foodborne disease organism. Also, 26% of
the fresh potatoes and 30% of fresh radishes tested positive for Listeria organisms.
While there is another common misconception is that healthy employees do not harbor
bacteria. Humans have their own natural population of bacteria (part of the normal
flora), and some are the variety that cause foodborne diseases. At least 80% of the
populations are carriers of bacteria that cause Clostridium perfringens food poisoning.
Also, 30 to 50% of the populations have staphylococcal food poisoning organisms in
their nasal passage or on their skin. Of course, sick employees are carriers of great
numbers of organisms that cause disease.Bacteria have specific nutritional and
environmental needs in order to survive and reproduce. They are as follows: food,
moisture, proper atmosphere, pH, temperature, and inhibitory substances. (a.) Food.
Bacteria have various food preferences. Those of public health concern like the same
kinds of food we like; (b.) There must be adequate moisture for bacteria to grow. The
amount of moisture needed is defined by the term water activity (aw). Fresh beef with a
high aw(0.99) will support rapid bacterial growth. However, cured beef jerky with a lower
aw(less than 0.85) will not. (c.) Atmospheric Requirements. Somebacteria grow rapidly only
15
in the presence of free oxygen; others require the absence of oxygen; some grow in
both atmospheres and even others may have special atmospheric requirements.
Cooking drives off oxygen; stirring, mixing, and beating foods introduce oxygen. (d.) The
pH of the bacteria's environment is a measurement of the degree of acidity or alkalinity.
The scale is 0 - 14. Most foods occupy the pH scale from 2.3 (which is acidic) to 8.0
(which is slightly alkaline). A pH of 7 is neutral. Most bacteria of public health concern
grow best at pHvalues between 4.6 to 7.5. Examples of food pH are as follows (in
decreasing order of acidity):lemons, 2.3; vinegar, 3.0; tomatoes, 4.2; bread and ground
beef, 5.5; ham, 6.0; corn, 6.3;chicken, 6.4; milk, 6.5; fish, 6.8; pure water, 7.0; and egg
white, 8.0. Mixing foods of different pHchanges the pH of the mixture. (e.) Some
spoilage bacteria grow best at refrigeration temperatures. Some othersgrow best at
temperatures above 120°F. Those of public health concern grow best between 60°and
120°F.Inhibitory Substances from bacteria themselves, or as a natural ingredient of food or
added during food processing may slow down, stop or inhibit growth of some bacteria or
enhance the growth of others. Salted ham is a good example. Because of the salt
concentration, spoilage bacteria growth is inhibited. However, the condition supports the
growth of common food poisoning bacteria.It is important to understand these things in
order to appreciate what influences bacterial growth, or why some foods support
bacterial growth in one form but not in another. (Adnan, 2008)

Local Literature
Concessionaires of food services must be always present during school days to serve
at the DLSU-D canteen. All food being served should be free from contamination to
prevent health problems. The institution have the right to determine brands of LPG, soft
drinks, juices, bottled water, ice and beverages that will be sold and has reasonable
prices. All concessionaires must undergo annual physical examination to ensure health
and safety of the customers to be catered. In terms of wearing uniform: using of apron,
hair cap/ net, I.D., gloves if necessary is needed. Government permits are also
necessary these permits are business permit, sanitary permit and, fire and safety
permit. Servers shall be directly in- charge with the cleanliness and sanitation of the
entire Leased premises at all times and shall undertake to maintain a high standard of
hygiene, sanitation and other sanitary practices to promote and address ecological
concerns in operating the canteen service. These canteens are being inspected by the
Head of Material Reproduction Office (MRO) and by the University Clinic. They shall
have the right to access all areas of the Leased Premises at any and reasonable times.
17
The purpose is to inspect and observe the quality of foods and beverages rendered
(MRO 2011).
Food safety is the assurance that the food supply does not pose an unacceptable risk to
human health. A number of developments point to the urgent need for an effective foodsafety
program. Among these are: (1.) Rapid urbanization; (2.) Increased demand for convenience food; (3.)
Increased travel; (4.) increased consumption of fruits and vegetables; (5.) Interest in ethnic and non-
traditional food; (6.) Novel foods; (7.) New processing and handling technologies; (8.) Emerging
pathogens; and (9.) Immune-compromised and susceptible populations. These developments,
along with trade liberalization in agriculture and food productspoint to the need for aneffective national
food safety program in the Philippines.Although Philippine legislation and related issuance provide for
various aspects of foodsafety, the absence of a clear statement of national policy on food safety and
the numberof agencies involved have led to overlaps and gaps in the implementation of
thisprogram. Monitoring and surveillance programs covering food borne diseases areimplemented
by the Department of Health."Food safety" implies absence or acceptable and safe levelsof
contaminants, adulterants, naturally occurring toxins orany other substance that may make food
injurious to healthon an acute or chronic basis(Lizada, 2007).
Food is inherently safe, particularly if it has a history of traditional use. However, exposure to
hazardous contaminants, the application of novel processes and technologies, and poor handling can
render food unsafe for consumption. A hazardous contaminant orhazard in food is any “biological,
chemical or physical agent in, or condition of, foodwith the potential to cause an adverse health effect”
(FAO/WHO, 2006 b).Biological hazards include pathogens that are highly infectious at low levels, e.g.
Hepatitis A virus, Shigella, E. coli O157:H7 salmonella. They also include E. sakazakii associated
18
with infant formula. Chemical hazards include toxins of fungal or algal origin, dioxins, heavy metals
(mercury, lead and cadmium), polyaromatichydrocarbons in smoked food, and pesticide and
veterinary drug residues. Some food plants and animals naturally contain toxins such as alkaloids,
cyanogenicglucosides, antinutrients, neurotxins and allergens. Acrylamides and Tran’s fats are
examples of unintended by-products of food processing. Additives that are not permitted for food
use or added in excess of allowable levels are also health hazards. Physical hazards include bone
fragments, glass, metal and pebbles.Although the Philippines implements a number of food safety-
related activities, a unified national program is lacking. The World Health Organization (WHO)
has provided the framework for the design of such a program, and a Philippine Food Safety proposal
guided by this framework has been presented in various forums. Unfortunately, the initial attempts to
actualize this proposal have not been sustained. There is a need to reiterate the need for
and resume discussions on this proposal. Food security and food safety has been described
as“A situation that exists when all people, at all times, have physical, social and economic access to
sufficient,safeand nutritious food that meets their dietary needs and food preferences for an active and
healthy life.” (FAO food security definition, 2005)
Foreign Studies
Microbial food borne illness or food poisoning occurs commonly throughout the
world. It is estimated that in the United States alone, more than 75 million episodes
occur annually, resulting in approximately 5, 000 deaths per year. Close to one in five
episodes of diarrhea is likely to be due to a food borne disease. This means that the
average person in the United States will have once every three to four years.
Fortunately, most people recover from an episode of food borne illness without any long
19
term complications This topic review discusses the causes, signs and symptoms and
treatment of food borne illness, along with ways to avoid it. (Acheson, 2009)
Personal hygiene is the best way to stop bacteria from contaminating and
spreading into new areas. Hands are the greatest source of contamination. Hands must
be washed constantly throughout the day. Hand and nailbrushes, antibacterial soaps
and disposable gloves should be part of every restaurant, even if not required by the
law. Proper training and management follow- up is also critical. Every employee must
practice good basic hygiene: short hair or hair contained in a net, clean shaven or facial
hair contained in a net, clean clothes/ uniform, clean hands and short nails. No
unnecessary jewelry, A daily shower or bath, No smoking or in near the kitchen
(Arduser and Brown, 2005)
The food sys tem is a complex , concen t ra ted and dynamic cha in
o f ac t i v i t i es tha t begins with the production of raw agricultu ra l
commod i t ies on fa rms, o rchards , and ranches and moves to value-added
processed and manufactured products and then to retail food stores and foodservice
establishments (restaurants and institutions) where they are merchandised,
prepared, and sold to consumers. Each sector of the food system is un ique
in s i ze , scope and d ive rs i t y and has evolved and adapted to changes in
demo-graphics and lifestyles, science and technology and consumer
demands. To more fully comprehend the role of sanitation and food safety in
the food industry. It is important tounderstand the uniqueness ofeach sector of the
food system (Marriot, 2006)
20
In recent years,the U.S.retail food industry has also experienced
unprecedented consolidations and structural changes
throughm e r g e r s , a c q u i s i t i o n s , d i v e s t i t u r e s , i n t e r n a l growth, and
new competitors.There are over224,000 food stores in the United States,with
grocery stores (including supermarkets,commerce stores,and small grocery
stores)accounting for more than 96% offood storesales.The average retail
food store stocksbetween 25,000 and 40,000 food items andprovides consumers with
a wide variety of products.Food retailers are striving to increasecustomer
satisfaction by developing andexpanding prepared and convenience foodsand
providing other products and services.Supermarkets are meeting consumer demandfor
convenience by offering a wide variety of products in departments such as deli
foods,prepared for takeout, in store bakeries,andfresh seafood.Food
sanitation plays a veryimportant role in the retail food industrybecause cleanliness is
the top factor thatconsumers rank as extremely important inselecting a supermarket
(Marriot, 2006).
Ensuring safe food is an important public health priority for our nation. For years
regulatory and industry food safety programs have focused on reducing the incidence of
foodborne illness. Despite these efforts, the 1996 report "Reinventing Food
Regulations" [National Performance Review] concluded that foodborne illness caused
by harmful bacteria and other pathogenic microorganisms in meat, poultry, seafood,
dairy products, and a host of other foods is a significant public health problem in the
United States.The National Performance Review Report looked at the occurrence of
foodborne illness from a farm-to-table perspective. It did not attempt to define the scope
21
of the problem within specific sectors of the farm-to-table continuum. In order to
determine the effectiveness of regulatory and industry food safety programs within
foodservice and retail food store facility types, a study was needed that would assess
information associated with the occurrence of foodborne illness and be specific to this
segment of the industry (retrieved from
http://www.fda.gov/Food/FoodSafety/RetailFoodProtection/FoodborneIllnessandRiskFa
ctorReduction/RetailFoodRiskFactorStudies/ucm089696.htm on 2004)
In order to improve the safety of refrigerated ready-to-eat food products prepared
at retail deli departments, a better understanding of current practices in these
establishments is needed. Food employees in deli departments at six chain and three
independent retail establishments in Maryland and Virginia were observed, using
notational analysis, as they prepared deli products for sale. The frequency of contact
with objects and deli products before sale, hand washing and glove changing during
preparation, and equipment, utensil, and surface cleaning and sanitizing was
determined. Compliance with the U.S. Food and Drug Administration's 2005 model
Food Code recommendations, which must be adopted by the individual state and local
jurisdictions that are responsible for directly regulating retail establishments, was also
assessed. Observations indicated there were a large number of actions for which hand
washing was recommended at independent and chain stores (273 recommended of
1,098 total actions and 439 recommended of 3,073 total actions, respectively).
Moreover, 67% (295 of 439) of the actions for which hand washing was recommended
at the chain stores and 86% (235 of 273) of those at the independent stores resulted
from employees touching non-food contact surfaces prior to handling ready-to-eat food.
22
Compliance with hand washing recommendations was generally low and varied
depending on store type with independent stores exhibiting lower compliance than chain
stores (5 instances of compliance for 273 recommended actions and 73 instances of
compliance for 439 recommended actions, respectively). Potential risk mitigation
measures that may reduce the frequency of hand washing actions needed during ready-
to-eat food preparation in retail deli departments are discussed. More research is
needed to determine the impact of such measures on food safety (Joint Institute for
Food Safety and Applied Nutrition, 2010).
Protecting the public from foodbome illness is critically important and remains a
major public health responsibility. Nonetheless, it has been reported that each year in
the U.S. approximately 76 million cases of foodbome illness occur, 300,000 of which
require hospitalization and 5,000 of which are fatal (Centers for Disease Control and
Prevention [CDC], 2009). More Americans now dine out, and do so more frequently,
than ever before (Ebbin, 2000; Kant &Graubard, 2004). Numerous studies have called
for increased food handler training (FHT), one as far back as 1938 (Jackson, 1954).
Many jurisdictions have implemented food handler training programs; some are
mandatory, some are not. Only a few have attempted to assess the outcomes of such
training. One study conducted food handler focus groups to learn about perceived
barriers to proper hand hygiene among food service workers and factors that promoted
good hand hygiene (Pragle, Harding, & Mack, 2007). The response rate was very low,
at 9%; thus, the results cannot be generalized beyond their specific sample.Training for
managers has been shown to have a positive impact on sanitary conditions in
restaurants (Cates et al., 2009; Cotterchio, Gunn, Coffill, Tormey, & Barry, 1998;
23
Hedberg et al., 2006). One of these studies (Cotterchio et al., 1998) found that both
mandated and voluntary manager training resulted in better inspection scores than
establishments participating in no manager training at all. Another of these studies
reported on an eight-state collaborative project that showed the presence of a certified
kitchen manager, but not food worker training, to be associated with a reduced risk for
foodbome illness outbreaks (Hedberg et al., 2006). Finally, another of these studies
showed that having a certified kitchen manager present in the establishment resulted in
fewer critical violations (Cates et al, 2009).
Computer files containing all routine food establishment inspection data for two
time periods were received from the health department: the four years before the
implementation of FHT (2001-2004) and the three years after (2005-2007).Violations
related to food handler behaviors were the ones of greatest interest for evaluating the
FHT program. Violations unrelated to food handler behaviors, not covered in the FHT
course, and generally considered outside of the control of a food service establishment
employee (e.g., placement of hand washing sinks or the adequacy of plumbing) were
used as quasiexperimental control variables. Determinations of which violations were
considered food handler-related and which were not were made by the KCMO-HD
individuals responsible for food establishment inspection and training programs
(Averett, 2011).
Safe handling of food in restaurants is a basic element in the reduction of
foodborne illness. We investigated knowledge and practices about food safety by food-
handlers in restaurants in Ramallah and Al-Bireh district of Palestine. A high proportion
24
of workers in the restaurants had no previous experience in other restaurants and
63.4% had received no training on food sanitation and safety. Most of the restaurants in
the refugee camps, villages and towns had only 1 worker. Restaurants lacked basic
conditions for food sanitation and safety, such as hot water in most and cleaning
materials in some. Many workers had poor personal hygiene practices. Training is
needed for restaurant owners and staff to improve food handling practices and
standards. (US National Library of Medicine National Institutes of Health). Poor food
preparation, handling, or storage can quickly result in food being contaminated with
germs and may lead to illness if the contaminated food is eaten. Contact your local
health department to obtain the local regulations and standards for food safety and
sanitation and to ask about the availability of a food handler course in your area. The
best way to wash, rinses, and disinfect dishes and eating utensils is to use a
dishwasher. If a dishwasher is not available or cannot be installed, a three-compartment
sink will be needed to wash, rinse, and disinfect dishes. A two-compartment or one-
compartment sink can be used by adding one or two dishpans, as needed. In addition to
three compartments or dishpans, you will need a dish rack with a drain board to allow
dishes and utensils to air dry. A person affected by a food borne illness may attempt to
obtain financial compensation for his or her illness by pursuing legal action against the
rims that produce, process, distribute, cook, or sell the food product that allegedly
caused the illness. In order to prevail in food borne illness litigation, people iling the
lawsuit, (plaintiffs) must prove by a preponderance of the evidence that the food
supplier (defendants) committed wrongful acts that caused harm to the plaintiffs.
(University of Hawaii at Manoa).The best defense to any future lawsuit is prevention,
25
through compliance with the Good Food Safety Practices. Even if the defendant is
found liable, punitive damages can be avoided and the damages may be reduced if the
defendant can show that (1) it took “reasonable care” when producing, handling, and
selling the food product; (2) it used state-of-the art technology in producing the food
product; and (3) it complied with laws, regulations, and guidelines designed to prevent
the harm suffered by a plaintiff. A defendant who follows the safe food handling
requirements and has documentation to prove it is more likely to be found to have
exercised reasonable care and control to prevent contamination. Thus, the defendant
taking these preventative measures has better defenses than a defendant with no safe
food handling procedures in place.(Adnan, 2008)
In 2003, the World Health Organization (WHO) and Food and Agriculture
Organization (FAO) published the Codex Alimentarius which serves as a guideline to
food safety. The Codex Alimentarius (Latin for "Book of Food") is a collection of
internationally recognized standards, codes of practice, guidelines and other
recommendations relating to foods, food production and food safety.Its name derives
from the Codex AlimentariusAustriacus.Its texts are developed and maintained by
the Codex Alimentarius Commission, a body that was established in 1963 by the Food
and Agriculture Organization of the United Nations (FAO) and the World Health
Organization (WHO). The Commission's main aims are stated as being to protect the
health of consumers and ensure fair practices in the international food trade. The Codex
Alimentarius is recognized by the World Trade Organization as an international
reference point for the resolution of disputes concerning food safety and consumer
protection. The Codex Alimentarius officially covers all foods, whether processed, semi-
26
processed or raw, but far more attention has been given to foods that are marketed
directly to consumers In addition to standards for specific foods, the Codex Alimentarius
contains general standards covering matters such as food labeling, food hygiene, food
additives and pesticide residues, and procedures for assessing the safety of foods
derived from modern biotechnology. It also contains guidelines for the management of
official (i.e., governmental) import and export inspection and certification systems for
foods.The controversy over the Codex Alimentarius relates to a perception that it is a
mandatory standard for the safety of food, including vitamin and mineral supplements.
Supporters of the Codex Alimentarius say that it is a voluntary reference standard for
food and that there is no obligation on countries to adopt Codex standards as a member
of either Codex or any other international trade organization. From the point of view of
its opponents, however, one of the main causes of concern is that the Codex
Alimentarius is recognized by the World Trade Organization as an international
reference standard for the resolution of disputes concerning food safety and consumer
protection.[2][3] Proponents argue that the use of Codex Alimentarius during international
disputes does not exclude the use of other references or scientific studies as evidence
of food safety and consumer protection. (retrieved from

Heavy metal poisoning occur frequently when acid foods (such as lemonade)
andcarbonated beverages come in contact with such heavy metals as copper, zinc,
antimonyand cadmium. (Adnan, 2008)
The food safety problems of the food industry can occur at any stage of the
foodchain and at any of the steps during the processing of the product. Most of these
27
foodsafety problems are within the capability of the individual companies to solve as
indicatedby the examples done by other companies. Longer term solutions to other
problems wouldrequire collaboration or cooperation with others in the industry, with
industry association,academic and research institutions, private consultants and
certainly with the governmentregulatory agencies and the market or customer of the
products. By implementing HACCP and incorporating the HACCP pre-requisites and
HACCPmethodology in the company’s Standard Operating procedures as embodied in
a writtenOperations Manual, many of the problems can be controlled All companies
should strive tomake documentation a part of the company culture (retrieved from

Local Studies
There are about 5,000 registered food manufacturing establishments in the
country, accounting for 25% of the total manufacturing sector. About 90% are small and
medium enterprises, but the 10% large establishments produce 90% of output. Most
small and medium food manufacturers are family-owned and are managed as single
proprietorships but are registered as corporations with family members as the
incorporators. Interestingly, many companies were started and developed by women at
home, with the men leaving their employment and taking active management when the
company had grown with expanded market.Unregistered micro to small enterprises
(“underground “food manufacturers ) could be 10 times that figure. Although producing
28
mostly ready-to-eat and street food, thisunregistered sector imposes a significant impact
on food safety in the country.The agencies of government concerned with food safety
are as follows: (1.) Department of Health; (2.) Bureau of Food and Drugs; (3.) Health
Department of Local Government Units; (4.) Department of Agriculture; (5.) Bureau of
Fisheries and Aquatic Resources; (6.) National Meat Inspection Service; (7.) Philippine
Coconut Administration; (8.) National Food Authority (rice and corn) (retrieved

The living dangers in food preparation: choose sources wisely, watch out for
toxins, and for goodness’ sake, wash your hands. Every day we prepare and consume
different types of food. Some are presented in different ways, and some are prepared
longer than the others. While food flows from receiving, storage, preparation and
cooking areas until it reaches the table for consumption, there are hazards along the
way that may cause food to become unsafe. In our May-June 2007 issue, we identified
three hazards to food safety: physical, chemical and biological hazards. Of these three,
biological hazards present a major threat to food safety. Biological hazards are
microorganisms such as viruses, parasites, fungi and bacteria. Let us study them
closely so that we will understand how to deal with them: VIRUS Viruses are protein-
wrapped genetic material, the smallest simplest known life form. Viruses do not
reproduce in food because they require a living host to reproduce; however, they may
survive cooking or freezing, and they can be transmitted to people by way of the food,
utensils or equipment. They can cause several serious illnesses, including Hepatitis A,
29
which causes inflammation of the liver. Viruses can contaminate food through
foodservice employees’ poor hygiene, contaminated food and water supplies, or
shellfish harvested from sewage-contaminated waters. An important defense against
food-borne viruses is to practice proper personal hygiene, especially through hand
washing. PARASITES are micro-organisms that need a host (supporting organism) to
survive. The most common parasite that contaminates food is Trichinellaspiralis, a
roundworm sometimes found in pigs. If not killed by thorough cooking or proper
freezing, its larvae can cause trichinosis, a disease that causes abdominal and
muscular pain. Another parasite is the Anisakis roundworm in fish. People who eat raw,
marinated, or partially cooked fish such as sushi, may be at risk of becoming infected
with this parasite. Other parasites that may pose significant food and water safety
hazards include Cryptosporidium parvum, a parasite that lives in the intestines of cattle
and other animals. Drinking water supplies contaminated with high levels of runoff from
farms or slaughterhouses have been implicated in outbreaks caused by this parasite.
Another parasite is Toxoplasma gondii, which causes toxoplasmosis, an infection of the
central nervous system. Individuals with compromised immune systems, such as the
very young, or very old, pregnant women, cancer patients undergoing chemotherapy,
and HIV-infected people, are most at risk. Toxoplamosis is caused by ingestion of raw
or undercooked meat contaminated with this parasite or contaminated with fecal matter.
Another parasite that spreads through person-to-person contact or contaminated food
or water, Giardia lamblia, is the most common cause of waterborne intestinal diseases.
The simplest and most effective way to prevent the disease caused by this parasite is
proper handwashing. FUNGI range from microscopic, single-celled plants to
30
mushrooms. Fungi are in the air, soil and water. Molds and yeast are types of fungi.
Individual mold cells are usually microscopic, but mold colonies may be seen as fuzzy
growths on food. The main damage caused by molds is food spoilage, but some molds
also produce toxins that can cause illness, infections, and allergic reactions. Some
toxins survive cooking, such as botulinum toxin. Molds can grow on almost any food, at
any storage temperature, and under any conditions. Freezing prevents mold growth, but
does not destroy them. If mold is not a natural part of food, such as those in blue
cheese, it should be discarded. Yeasts require sugar and moisture to survive. These are
commonly found in food such as jellies and honey. Yeasts spoil food by consuming it.
Yeast spoilage appears as bubbles, with an alcoholic smell or taste, pink discoloration,
or slime. FISH TOXINS Although there are no specific regulations in the Philippines in
certifying fish and seafood suppliers, the best food-safety control for fish is to purchase
them only from reputable and certified suppliers. Examine incoming deliveries for signs
of spoilage and carefully select the kinds of fish that are served, noting the following;
some species of amberjacks, barracuda and other tropical reef fish may eat smaller fish
that, in turn, have eaten smaller fish that have eaten algae carrying ciguatoxin.
Ciguatoxin is naturally occurring toxin (which makes it a biological hazard) that is not
destroyed by cooking. Ciguatera, resulting from ingestion of fish with elevated levels of
ciguatoxin, is characterized by vomiting, itching, nausea, dizziness, hot and cold
flashes, temporary blindness, hot and cold sensory reversal, and sometimes
hallucinations. Eating tuna, bluefish or mackerel which has been time-temperature
abused can cause scombroid intoxication. Symptoms often resemble an allergic
reaction and include flushing of the skin, sweating, a burning or peppery taste in the
31
mouth, nausea, headache, facial rash, hives, edema, diarrhea and abdominal cramps.
This illness is caused by histamine, an odorless tasteless chemical that is not destroyed
by cooking. Puffer fish, moray eels and freshwater minnows contain natural toxins.
PLANT TOXINS Many plants such as fava beans, rhubarb leaves, jimson weed and
water hemlock have been implicated in food-borne illness outbreaks. Food made from
plants–such as honey from bees that gather nectar from mountain laurel, milk from
cows that eat snakeroot, and jelly made from apricot kernels–also has been associated
with food-borne outbreaks. Some varieties of mushrooms are naturally poisonous.
Since poisonous and non-poisonous mushrooms often look alike, make sure that you
use only those purchased from reliable and reputable suppliers. Remember that
freezing and cooking do not destroy all plant toxins. BACTERIA Of all microorganisms,
bacteria provide the most common threat to food safety. Bacteria are ling single-celled
organisms. They can cause illnesses in two ways: Pathogenic (infectious, disease-
causing) bacteria can multiply rapidly in favorable conditions in potentially hazardous
foods, while Toxigenic (poisonous) bacteria can produce harmful toxins. Inside their
cells, certain bacteria produce protective thick-walled structures called spores. Spores
do not reproduce, but they enable the bacteria to survive some cooking and freezing
temperatures and the destructive effects of cleaning and sanitizing solutions. Generally
bacteria thrive in slightly acidic food (pH 4.6–7.5) with enough moisture (Available
water,Aw= 0.85 and above), and grow rapidly within the Temperature Danger Zone or
TDZ (5 deg. C to 57 deg. C). Potentially hazardous food exposed within the TDZ for
more than four hours may already be considered unsafe. It is best to keep food safe by
32
keeping it out of the TDZ and to observe proper cooking temperatures. (F&B World-
Gerodias, 2007)
Cross-contamination is the transfer of harmful microorganisms, such as viruses
and bacteria, from one surface to food. Cross-contamination may occur in several ways:
1) from food to food; 2) from utensil/equipment to food; and 3) from people to food. How
does this happen? When raw foods come into contact with ready-to-eat foods,
pathogens are transferred to make the latter potentially hazardous. Chopping boards
and knives, when used on raw foods that require higher cooking temperature, and then
later on used on raw foods that require lower cooking temperatures, without washing,
rinsing and sanitizing them, are classic examples of cross-contamination. People can
also be a source of food contamination, especially when they fail to wash their hands
after using the toilet, after handling raw foods, and even when they wipe their hands on
their aprons! How then do we prevent cross-contamination? Follow these easy-to-
remember tips to put a stop to cross-contamination in the kitchen: Purchasing and
Receiving – Separate raw meat from other foods in the receiving area. Require your
suppliers to place these foods in plastic bags to prevent their juices from dripping onto
other foods. It is best to avoid ready-to-eat foods being delivered at the same time as
raw foods. Storing – Place raw meat in containers to prevent their juices from dripping
onto other foods. Juices contain harmful bacteria if they are present on the meat. Store
ready-to-eat foods away from raw foods. If you only have one chiller, put foods that
require higher cooking temperature on the bottom shelf, while ready-to-eat foods must
be stored on the top shelves. Thawing – Completely thaw meat before cooking so it
cooks evenly. Ensue juices do not drip onto other foods during thawing in the
33
chiller. Holding and serving food – Even food servers, guests, and condiments may
be responsible for cross-contamination. To avoid this, make sure to do the following:
(a.) On buffet tables and self-service areas, make sure that guests return with fresh
plates; (b.) If possible, provide your guests with a handwashing station; (c.) Watch out
for children playing with condiments and dipping their hands into buffet foods; (d.)
Separate raw foods such as sushi and Mongolian barbecue ingredients from cooked or
ready-to-eat foods; (e.) Serving utensils must be kept in food with the handle sticking
out of the food. Utensils may also be kept in an ice water bath, cold running water bath,
or water that is maintained at 57 degrees Celsius or higher. (f.) Use ice scoops with
handles or tongs to place ice in glasses. Cross-contamination is definitely one of the
major causes of food borne illnesses. It is always best to prevent it from happening in
our food facilities. (F&B World Magazine, 2007)
Some companies find difficulty in getting competent personnel who can be
responsible for food safety. This is more felt by companies located in provincial
locations. Participation in public seminar-workshops on GMP and HACCP planning and
implementation offered by various government agencies, extension service of
universities and non-government organizations helps in developing in-house
competence in food safety. Other companies avail of consultancy services offered by
food safety consultants. Unskilled food handlers are a common food industry problem.
Company pre employment training is often inadequate particularly with respect to
sanitary food handling and personal hygiene. Several innovative solutions have been
done. Apprenticeship is one. A prospective employee, who has passed health
requirements first train as an apprentice with a team of regular workers . When the
34
tutors see that the apprentice can do the operation well, she is given an oral and written
examination before being formally employed by the company. Some companies avail of
in-house training workshops on various aspects of food safety. Hygiene monitoring had
always been a problem in the industry. Use of simple checklists and frequent random
checks has been helpful in solving this problem. An innovative systems implemented by
one company used a video camera to record habits and mannerisms that violate
personal hygiene rules. The recording is shown to the employee corrective measures
are discussed. With the newer technology of cell phone cameras, this practice became
easier to do.Jewelry check nail checks, swabbing of hands have been some solutions to
avert contamination from personnel. In another company, each employee carries a
personal handbook of company rules and regulation, most of which were about
personal hygiene. An accompanying self checklist is filled up daily and submitted to
management as a hygiene monitor. A variation of self check is the buddy check. There
had been limitations of these methods, but a regular audit by the responsible person
minimizes problems.The food safety problems of the food industry can occur at any
stage of the food chain and at any of the steps during the processing of the product.
Most of these food safety problems are within the capability of the individual companies
to solve as indicated by the examples done by other companies. Longer term solutions
to other problems would require collaboration or cooperation with others in the industry,
with industry association, academic and research institutions, private consultants and
certainly with the government regulatory agencies and the market or customer of the
products. By implementing HACCP and incorporating the HACCP pre-requisites and
HACCP methodology in the company’s Standard Operating procedures as embodied in
35
a written Operations Manual, many of the problems can be controlled All food
establishment should strive to make documentation a part of the company culture.
