Livestock-associated MRSA has been identified in a turkey at a farm in East Anglia.
A spokesperson for the Animal Health and Veterinary Laboratories Agency said the infection was found in one bird.
Environmental groups have said the risk of human infection is very low.
Steve Wearne, director of policy at the Food Standards Agency, said: “Any risk of contracting MRSA through meat from animals with these bacteria is very low when usual good hygiene and thorough cooking practices are observed.
“All poultry should be handled hygienically and cooked thoroughly to destroy any bacteria that may be present.”
