European Medicines Agency updates antibiotics advice
The EMA has updated its scientific advice on the risk categorisation of antibiotics for use in animals.
Four new classes of antibiotics have been identified

The European Medicines Agency (EMA) has updated its scientific advice on the risk categorisation of antibiotics for use in animals.

The updated advice from EMA’s Antimicrobial Advice Ad-Hoc Experts Group (AMEG) includes new classes of antibiotics and takes into account the need to use antibiotics in animals versus the risk of antimicrobial resistance to public health.

The main change in the new advice is that the four new classes of antibiotics A to D have been identified, replacing the previous three categories. They are:
  • category A ('Avoid') includes antibiotics currently not authorised for veterinary use. These medicines cannot be used in food-producing animals and should only be given to pets under exceptional circumstances;
  • category B ('Restrict') refers to quinolones, third- and fourth-generation cephalosporins and polymyxins. These are critically important in human medicine and their use in animals should be restricted;
  • category C ('Caution') covers antibiotics for which alternatives for human use generally exist, but only few alternatives are available in certain veterinary indications. They should only be used when there are no suitable antibiotics in category D;
  • category D ('Prudence') covers antibiotics that may be used in animals in a prudent manner. Group treatment should be restricted to situations where individual treatment is not feasible.
Welcoming the guidance, Chris Lloyd, secretary-general of the Responsible Use of Medicines in Agriculture Alliance (RUMA) said the advice identifies where a lack of alternative products challenges the treatment of disease in some species. As such, he notes that the updated advice will be particularly helpful in guiding future targets and policy in UK farm animal health and welfare.

“The EMA’s AMEG constantly reassesses the impact on human health of using different antibiotics in animals, alongside the need to treat disease in animals for health and welfare reasons. This is a unique approach globally,” explains Mr Lloyd.

“The advice also focuses on specific resistance issues within the geographical region of Europe, which is why it is used by the government’s Veterinary Medicines Directorate, RUMA, and most professional veterinary organisations within the UK as the key source of expert guidance.”

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

New guidance for antibiotic use in rabbits

New best practice guidance on the responsible use of antibiotics in rabbits has been published by the BSAVA in collaboration with the Rabbit Welfare Association & Fund (RWA&F).

The guidance is free and has been produced to help veterinary practitioners select the most appropriate antibiotic for rabbits. It covers active substance, dose and route of administration all of which are crucial factors when treating rabbits owing to the risk of enterotoxaemia.

For more information and to access the guide, visit the BSAVALibrary.
