Comparison of international legislation and standards on veterinary drug residues in food of animal origin

Current legislation governing monitoring of drug residues in foodstuff of animal origin is being revised at the European level. This study provides a qualitative comparison of the legislation, public and private standards in the European Union, the United States of America (USA) and the Eurasian Customs Union/Russia. We made a quantitative comparison of Maximum Residue Levels (MRLs) applied in each region for pork kidneys for tetracycline (with a focus on doxycycline), penicillin and chloramphenicol. The Customs Union generally applied lower levels than the other regions, with MRLs for tetracyclines in pig kidneys being 1200 times lower than those applied in the USA. Growing consumer interest and concern about chemicals in their food could be leveraged to support and enhance the implementation of new initiatives to improve veterinary public health. Farmers and veterinarians could help reduce findings of drug residues in meat through the judicious use of preventive actions when using veterinary medicine.
