Project Title:

Detection of Cephalosporins and quATernary ammonium compounds in food

Project Coordinator:

Dr Martin Danaher

Project Abstract

This project will carry out research into residues of two groups of substances, namely, Cephalosporin antibiotics and Quaternary Ammonium Compounds (QACs). QACs are an emerging group of contaminants originating from disinfectants and are currently of concern for the dairy industry. Cephalosporins are a key antibiotic used in the treatment of bacterial infections in both humans and farm animals. There is ongoing concern about their use in agriculture because of the potential development of antimicrobial resistance (AMR). There have been reports of cephalosporin residues in milk, poultry and aquaculture products due to inappropriate treatments. No confirmatory chemical tests are available on the island to detect these cephalosporin residues in food. This project will address this gap, by application and validation of a multiresidue cephalosporin LC-MS/MS method, which will be transferred to the official testing laboratory in Ireland, Veterinary Public Health Regulatory Laboratory (VPHRL, Backweston). In addition, methods will also be established at Teagasc to measure QAC residues in milk. Methods applied during this project will lead to new knowledge on the persistence of residues in milk. Residue stabilities during dairy product manufacture will also be investigated. Project research will provide new knowledge and tests to support the Irish Agri-food industry.
