4 SERBIA - FOOD SAFETY SYSTEM 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.

5 Programme of establishing the measures for animal health protection for 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

6 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

8 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

9 The prevalence: Depends of Region in R Serbia Domestic animals Souther - East Serbia sheep 98% (certain municipalities) Region of Belgrade - sheep and goats % South parts of Serbia - sheep 3.98%, cattle 4.54%, pigs 4.18% Wild animals Echinococcus granulosus - foxes % Echinococcus multilocularis - beaver (2012)

12 Cases at human population: In 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

13 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.

14 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

15 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

16 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
