Veterinary Medicine Residues

We have many years of experience carrying out veterinary medicines testing, providing services across the food supply chain. Our aim is to understand and meet the demands of the customer and to assist with any upcoming and emerging issues. The majority of veterinary medicines can be analysed by multi-residue screening methods, in addition we also offer a range of single residue methods.

Growing resistance to commonly prescribed antibiotics is one of the biggest public health threats of modern times, with the potential to cause 80,000 deaths in the UK over the next 20 years. Experts say the use of a range of NHS 'last-resort' antibiotics in farming is risking the lives of future patients.

Fera is the National Reference Laboratory for Veterinary Medicines Residues.

BBC's Panorama programme recently investigated if the commercial pressure to produce cheap meat and poultry is fuelling the rise of superbugs and meets the patients for whom the drugs have already stopped working. Fera has been carrying out residue testing for over 30 years, providing services across the food supply chain. Our experience is such that we know what to look for in any given foodstuff so can help you identify an appropriate testing regimen for your animal-based food ingredients and products.
