Anticoccidial drugs are widely used as additives in feed and as veterinary drugs for the prevention and treatment of coccidiosis in poultry and other animals. The economic damage caused by coccidiosis in modern poultry production is so serious that practically all poultry farms have resorted to feeding anticoccidial drugs as a feed additive to pullets and broiler breeders for 12 to 16 weeks and to broiler chickens for almost their entire life.

MRLs and MLs have been set for a number of these anticoccidial residues to reduce risks to human health. Codex Alimentarius has set the following MRLs for poultry: 500 µg/kg for muscle, 1000 µg/kg for fat/skin, 2000 µg/kg for kidney and 3000 µg/kg for liver. Creative Diagnostics provide a full list of antibodies, conjugates and test kits for the analysis of anticoccidial residues.
