Rational use  –  Food animals

Set up a program

A rational use initiative at individual farm level has to be adjusted to the local situation at the actual farm.

Animals are kept for different purposes – for food, as companion animals, for recreation and sports. There is a wide range of animal species that are being kept, and they are held in different animal husbandry systems. Programs on rational use thus have to be specific for the actual animal holding.

Promote animal health

Improved animal health is the base needed to be able to optimize antibiotic use, and rational use of antibiotic is not possible without including measures that increases the intrinsic health of the animal. This includes good hygiene, good nutrition, biosecurity, use of vaccines and to optimize housing conditions.

An initial step to set up a rational use initiative at the farm level is to analyze the animal health situation at the farm, if possible together with other professionals such as veterinarians and other husbandry experts. The level of animal health is a result of the management of a wide range of factors, which can be grouped as animal specific, husbandry system-dependent and management-dependent. The EPRUMA best practice framework for the use of antibiotics in food-producing animals provides building blocks that a farmer can implement to develop a farm-specific health plan.

Optimize antibiotic use

Animals can still get sick, even with high level of animal husbandry practices. When antibiotic treatment is indicated, it should be used as targeted treatment based on clinical diagnosis and, whenever possible, on the results of microbiological susceptibility tests, and using an antibiotic agent of as narrow-spectrum as possible. Several guidelines on prudent antibiotic use have been published by different stakeholders.

Questions to ask before initiating an antibiotic treatment to ensure that the treatment is justified:

  • Does the disease need antibacterial treatment or are there other options besides antibacterial treatment?
  • Will the potential risk of inducing resistance outweigh the benefit of treatment?
  • Will the antibiotic treatment work against the causative pathogen?
  • Will the antibiotic treatment pose risks to public health?

Components when evaluating appropriate use of antibiotics in the animal sector:

  • Application of measures to improve animal health (see PREVENT INFECTION: Non-human)
  • Record keeping of all antibiotic use that includes: name of antibiotic, date of treatment, animal treated, dose, length of treatment, indication (diagnosis), route of administration, name of prescriber, withdrawal time and name of person giving the treatment.
  • Regular analysis of antibiotic use records to identify
    • Non-therapeutic use such as use as growth promoter and routine use to prevent or control diseases during certain risk-periods (for example weaning of piglets)
    • Use of critically important antibiotics and under which indication
    • Animal health problems that need to be addressed
  • Implementation of corrective actions to counteract
    • Inappropriate antibiotic use
    • Animal health problems
