Veterinary Residues


Veterinary medicines are used within animal husbandry to treat sick animals or prevent disease in herds or flocks of animals. Residues from these drugs may be detected in a number of food types such as, meat, poultry, fish, eggs, milk (and associated products), crustaceans & shellfish, honey and ready meals.

Consumption of veterinary residues above the maximum residue limits (MRL) may result in development of antimicrobial drug resistance, hypersensitivity reaction, carcinogenicity, mutagenicity, teratogenicity, and disruption of intestinal normal flora.

Legislation for this group of compounds has been around since 1996.


Within Legislation, Groups’ A & B are of interest to the regulation (Directive 96/23/EC) and are applied to cows, sheep, goats, pig, horse, chicken and associated dairy products. There is also a requirement for aquaculture.

It generally applies to both producers (slaughter houses), and importer/exporters.
