Legal Framework:
Law on Veterinary Matters (OG RS, No. 91/05, 30/10, 93/12)
Multiplespecies diseases : Echinococcosis/hydatidosis
Law on Food Safety (Official Gazette of RS, No. 41/09)
Rulebook on method and procedure of performing official control of
food of animal origin and method of performing official control of animals
before and after slaughter (Official Gazette of RS, No. 99/10) –
postmortem inspection
Programme of establishing the measures for animal health protection
for 2013.
OIE seminar, Belgrade 15-17 October 2013
Programme of establishing the measures for
animal health protection for 2013. Dehelmintization of dogs and cats over three months against canine
tapeworms Echinococcus granulosus
In order to prevent the spread of parasite eggs in the environment, at
least 48 hours after treatment of dogs, their feces seem harmless .
The slaughter of animals for human consumption, owners who
slaughter animals for their own use, affected organs are safe by
boiling , incineration or processing in the rendering plant
The slaughterhouse is recorded each identified case of
echinococcosis and on the notify the veterinary inspection
OIE seminar, Belgrade 15-17 October 2013
IMPORTANCE
• Echinococcosis is a zoonotic disease caused by Echinococcus spp.
• The hosts: dogs and cats, carry the adult tapeworms subclinically.
• Dogs are particularly important - close relationships with humans.
• Intermediate hosts are initially asymptomatic
• Cysts in the liver and lungs, can lead to illness and death.
•The incubation period from months to years
OIE seminar, Belgrade 15-17 October 2013
The most common species - Serbia
• Echinococcus granulosus - sheeps/goats, cattle, pigs,
wild animals
• Echinococcus multilocularis - wild animals
• E. vogeli
• E. oligarthrus
• Eggs – dogs, cats, foxes
OIE seminar, Belgrade 15-17 October 2013
The prevalence:
Depends of Region in R Serbia
Domestic animals
• Souther - East Serbia – sheep 98% (certain municipalities)
• Region of Belgrade - sheep and goats - 12.3%
• South parts of Serbia - sheep 3.98%, cattle 4.54%, pigs 4.18%
Wild animals
• Echinococcus granulosus - foxes - 0.23%
• Echinococcus multilocularis - beaver (2012)

Cases at human population:
OIE seminar, Belgrade 15-17 October 2013
In 2012. there were 39 people who were infected*:
• Echinococcosis hepatis – 34 people
• Echinococcosis pulmonis – 1 person
• Echinococcosis alia non specificata - 4 people
Region of Central Serbia - 29 people
Region Vojvodina - 10 people
• The most of sick people are older then 15, with domination of
female population 61,5%
• It is detected over the year, there is no seasonal fluctuation
* Published report of Institute of Public Health of Serbia “Milan Jovanović Batut”
Echinococcosis is particularly
widespread in Serbia due to
Lack of knowledge of cattle/pig breeding
Lack of appropriate livestock and
Poor zoohygienic services regarding animal by product disposal
Holdings keep livestock with the dogs.
Real host becomes infected by eating infected liver and lungs
Vectors - oral intake of eggs that a real host throws feces.
Rural households are often the result of "intentional" feeding dogs
infected organs during pig slaughtering.
OIE seminar, Belgrade 15-17 October 2013
PREVENTION
Conduct regular eradication of helminthes of dogs, especially those
who are in contact with domestic animals and humans
Difficult to prevent exposure to Echinococcus spp. eggs from wild
animals;
Food safety precautions + combined with good hygiene.
Adequate removal of animal waste in order to prevent the circulation
of infectious material.
Education of people trough the media, broshures, liflets
OIE seminar, Belgrade 15-17 October 2013
PREVENTION
The hands should always be washed after handling pets, farming,
gardening or preparing food, and before eating.
In some areas, foxes could be treated with antiparasitic drugs in
bait, to decrease the prevalence of E. multilocularis.
Improve laboratory technics: molecular genotyping techniques, RT-
PCR and sequencing mitochondrial CO1 gene
Drugs: benzimidazolic, mebendazole , albendazole, praziquantel
OIE seminar, Belgrade 15-17 October 2013
FURTHER STEPS
The better system of recording the cases of echinococcosis in
slaughterhouses – link between animals/human health/food safety
tasks;
Twinnig Project – Proposal for IPA 2014: Data collection on zoonotic
diseases – Based on Directive 2003/99/EC on the monitoring of
zoonoses and zoonotic agents;
The offal’s analysis in foxes
