The European Parliament approved limits on the use of antibiotics in farm animals produced for food. The limits are aimed at keeping drug-resistant bacteria out of food. The legislation was adopted with 583 votes to 16 and 20 abstentions.The new regulations, which go into force in 2022, limit the use of antimicrobials as a preventive measure — in the absence of clinical signs of infection — to single animals. A veterinarian must approve and justify the use of antibiotics in cases where there is a high risk of infection. Additionally, treating a group of animals when one shows signs of infection should be a last resort. Antibiotics should be administered only after a veterinarian has diagnosed infection and prescribed antimicrobials.The new law also gives the European Commission power to reserve select antimicrobials for treating only humans, and not animals.Finally, the law also requires that imported foods meet EU standards and that antibiotics cannot be used to promote growth of animals.
