Antimicrobial Resistance

We support responsible antimicrobial use

We fully support changes made by Health Canada for how antimicrobials can be used to support animal health, including making medically important antimicrobials only available by veterinary prescription as of December 1, 2018.


How does antimicrobial resistance occur?

Do your part to lower the risk of antibiotic resistance in people. Use the right drug, for the right reason, at the right dose, for the right duration.

Antimicrobial resistance can occur in 3 ways:

  1. In any group of bacteria, there are some individual bacteria that are naturally stronger than others, meaning these stronger bacteria can survive an antimicrobial treatment and reproduce more of their kind, which in turn causes more resistance.
  2. Antimicrobial resistance can be transferred from one type of bacteria to another through genetic material, meaning more bacteria are able to survive a treatment, which in turn causes more resistance.
  3. A small percentage of bacteria may simply be naturally resistant to certain antimicrobials because the way they work is incompatible with the target bacteria. These bacteria are, and always have been, resistant to this type of antibiotic.  This sort of resistance does not lead to more antimicrobial resistance.

As little as possible, as much as necessary

A main reason to use antimicrobials in food animal production is to help manage disease. By having healthy animals, we have a healthy food supply, which in turn leads to healthy people.

Access to health management tools such as antimicrobials is important to veterinarians, farmers and pet owners to keep the animals in their care healthy and to promote good animal welfare. 

Understanding the importance of a One Health approach around antimicrobial use and the need to use these products responsibly, CAHI’s members voluntarily agreed to remove all growth promotion claims from antimicrobials that are important to human medicine by December 2018.  We have also created a new logo for animal antimicrobial product labels promoting responsible use.

Contains Antimicrobial. Use Responsibly.

To use antimicrobials “responsibly” is to:

  • Work with a veterinarian
  • Take steps to minimize the need to use antimicrobials through good animal husbandry, nutrition and vaccination programmes
  • When it is necessary to use antimicrobials:
    • use them for the full course of treatment
    • at the prescribed dose
    • use the right antimicrobial for the disease-causing bacteria, and where possible use one that is less important to human medicine.

Are There Alternatives?

There are some veterinary health products available that do show some antimicrobial properties.  There are also other animal health products (natural or conventional) that promote good animal health and help to avoid an infection, resulting in a reduced need to use antimicrobials.  Farmers are also continuously adopting best management practices like biosecurity which helps to keep harmful germs out of barns and herds or flocks. 

Researchers and animal health companies are continuously seeking alternatives to antimicrobials.
