Joint FAO/WHO Expert Meeting on Hazards Associated with Animal Feed

12-15 May 2015, Rome, Italy

Overview


Background

• 2007 expert meeting

• Ad hoc intergovernmental task force on animal feed

• Requested FAO/WHO to provide updated information on hazards of relevance to animal feed


3

• Update of the current state of knowledge on hazards associated with feed including feed and feed production technologies of increasing relevance

• Guidance on the most appropriate use of this information for risk analyses purposes

• Identify knowledge gaps to prioritize future work.

Meeting objectives


4

Included

• Hazards in animal feed presenting a risk for human health

• Impact of these hazards on animal health

• Hazards in water where relevant in accordance with the Codex definition of animal feed.

Scope


5

Excluded

• Potential wider impacts of hazards on animal health, welfare and productivity, food security - area for future work

• Veterinary drugs intentionally added to feed

• Antimicrobial resistance

• GMOs – subject to safety assessment prior to use

Scope


6

Implemented in line with procedures for provision of scientific advice

Inclusive in efforts to consider all available data • Background paper summarizing publicly available

data

• Additional information through its peer review by experts and stakeholders,

• Call for data

• information and expertise provided by the individual experts

• Resource people (biofuels, former food products)

Process/Approach


7

Hazards in feed may present an important risk for human health, and can have a negative impact on animal health and welfare

Stressed the importance of • Pursuing the prevention and control of hazards in

animal feed.

• Developing and implementing standards, guidelines and practical measures

• Action from multiple players is required to build upon what has already been done

• Ongoing and enhanced capacity development

Key Findings - general


8

• Challenges presented by the wide range of hazards and feed sources, including • need to generate the necessary data on some of these

contaminants (sampling approaches and sampling plans)

• collate those data, if feasible through a global platform

• develop the methodologies needed to facilitate such risk assessment.

• Role of the industry in generating data as well as authorities

• Importance of using this to identify and implement risk management measures

Key Findings - Risk assessment


9

• Codex Alimentarius work recognized – but more needed, explicit consideration of feed when developing or revising Codex texts for biological and chemical contaminants.

• Differences that exist between countries’ regulatory frameworks, and its impact – limited or no legislation and infrastructure feed safety management.

• The ongoing development of new technologies

- need institutional and regulatory frameworks

.

Key findings – standards and regulation


10

• Not feasible at international level • Country by country basis, consider specific

situation, e.g feed sources, production systems

• Codex guidance

• Consider other issues e.g. food security

• Changing environment in which feed is being produced and used (climate, farming practices, feed sources etc.) • regular review of potential hazards

• Awareness of the potential for new hazards

• be ready to take the necessary steps to manage these.

Key findings - prioritization


11

• Persistent organic pollutants (POPs) such dioxans (PCDDs), furans (PCDFs), dl-PCBs andl-PCBs;

• Veterinary drug residues;

• Organochlorine and other pesticides;

• Potentially toxic elements (PTEs) (e.g. arsenic, cadmium, lead, mercury);

• Mycotoxins;

• Plant toxins (e.g. genotoxic pyrrolizidine alkaloids and anti-nutritionals such as glucosinolates)

• Potential and emerging chemical hazards.

Chemical hazards


Chemical hazards Hazard POPs - dioxin, dl-PCBs, ndl-PCBs

Health impact Dioxins – reproductive, immune and endocrine systems are sensitive targets, especially in developing organisms NDL-PCBs difficult to identify

Source Natural and anthropogenic sources, processing (e.g drying with inappropriate foods)

Occurrence in feed Plants grown in contaminated areas, fish oil and meal from contaminated areas

Transfer feed to food Dependent on congener profile and lipid content of feed

Relevance for food safety only slowly eliminated and as such levels found in edible tissues and products are dependent on the levels in feed and also the duration of exposure.

Emerging issues/trends better define the risk associated with ndl-PCBs that are generally present at much higher levels in feed than dioxins and dl-PCBs


13

• Bacteria – Salmonella, Mycobacterium, Brucella, Clostridium spp, enterohaemorrhagic Escherichia coli, and Listeria

• Parasites - pasture and forage

• Viruses – data gap

• Prions – don’t forget lessons of the past.

Biological hazards


14

• Radionuclides

• Residues of nanomaterials, micro- and nano-plastics

• Other relevant materials - packaging.

Physical hazards


15

• Insects as feed

• Food waste and former food products

• Biofuel by-products

• Aquatic plants

• Marine resources

Feed sources and processes of increasing importance


16

• A lot of information

• Challenges - knowledge and understanding what is relevant for animal feed. • methods not validated for all relevant feed and feed

ingredients

• no reliable methods are available for a number of the identified hazards.

• Developed a table of information • overview of the methods available specifically for hazards in

feed

• scope of their application

Analytical Methods
