The project is one of a series initiated at the request of the Commission's Agricultural Services (DG VI) to provide RMs in support of Community Policy banning the use of growth promoting compounds in farm animals and the Directives laying down requirements for monitoring of undesirable substances in farm animals and products in Member States (86/469/EEC) and laying down criteria for reference methods used in pursuance of the monitoring programs (87/410/EEC).
The three drugs are broad spectrum antibiotics widely used in animal production either alone or in combination with other antibiotics. A major use is for the treatment of udder infections in lactating dairy cattle. OTC is often used for pigs.
The project will involve the production of lyophilised muscle and lyophilised milk:
- treated with the three antibiotics
- never treated with the three antibiotics.
The material will be mainly used by the National control laboratories.
Preparation of materials and initial stability studies in milk began in 1991.
