Antimicrobial resistance (AMR) is a major global threat of increasing concern to human and animal health. It also has implications for both food safety and food security and the economic well being of millions of farming households.
Food plays an important role in the development and spread of AMR. The presence of AMR microorganisms in agricultural production systems and food chains is a potential route of exposure for everyone. Good hygiene practices in agriculture, fundamental in achieving food safety, are also key to addressing antimicrobial resistance.
Microorganisms (bacteria, parasites, viruses and fungi) in food are potential food safety hazards. The relationship of the use of antimicrobials (agents that can kill microorganisms or stop them from growing) in food-producing animals and the emergence of resistant microorganisms in the food chain is a concern and has been the subject of numerous national and international consultations.
The extent to which the use of antimicrobial agents in food animals (including aquaculture), horticulture or humans contributes to antimicrobial-resistant microorganisms in humans varies between the different microorganisms and different regions.
When humans ingest antimicrobial-resistant microorganisms in food, some species of microorganisms may cause illness. These and other species may also serve as a source of transferable resistance determinants for other microorganisms, including human pathogens.
In recognising the need for a more general and multidisciplinary response to deal with AMR, in 2006 Codex established a first Task Force on Antimicrobial Resistance to develop science-based guidance on how to assess and manage the risks to human health associated with the presence in food and feed (including aquaculture) and the transmission through food and feed of antimicrobial resistant microorganisms. A second Task Force, recently established in response to the increased global attention to the serious threat of AMR to public health, will develop science-based guidance to enable coherent management of antimicrobial resistance along the food chain.
Other Codex texts on veterinary drugs and their residues, food hygiene, animal feed, also contribute to tackle AMR by preventing the development and minimizing the transmission of AMR through the food chain.
