Dimetridazole
Dimetridazole is a drug that combats protozoan infections. It is a nitroimidazole class drug. It has been banned by the Government of Canada as a livestock feed additive.
It used to be commonly added to poultry feed. This led to it being found in eggs. Because of suspicions of it being carcinogenic its use has been legally limited but it is still found in the eggs.
