The Animals and Animal Products (Examination For Residues And Maximum Residue Limits) Regulations 1997 and the Veterinary Medicines Regulations 2005 lay down legal requirements relating to the records that must be kept when veterinary medicinal products, which includes medicated feeding stuff are administered to farm animals.
If you are in the business of rearing, producing, or treating farm animals, which will end up as food intended for human consumption, you must keep a record of any veterinary medicinal product you give them or treat them with.
