Antimicrobial Stewardship

CAHI has actively supported antimicrobial stewardship for a long time

3 important reasons to prevent, control and treat disease in animals: minimize animal suffering, reduce healthcare costs, affordable food supply.

Responsible antimicrobial use in animals is important to animal medicine and in a One Health context, something CAHI members recognise.  With this in mind, here are some to CAHI’s activities in this area:

  • Lobbying Health Canada to end Own Use Importation and increase oversight of Active Pharmaceutical Ingredient use;
  • Committing voluntarily to remove growth promotion claims from product labels by December 1, 2018;
  • Encouraging Health Canada to take steps to align with veterinary antimicrobial use policies in other jurisdictions; and
  • Creating the responsible use logo for voluntary use on veterinary product labels.

As a result

Since December 1, 2018, a veterinary prescription is needed to use Category I, II and III medically important antimicrobials (MIA).

Other changes made by Health Canada included:

  • Ending Own Use Importation of MIA by animal owners effective November 13, 2017;
  • Increased oversight and new rules for the handling of Active Pharmaceutical Ingredients for veterinary use starting May 17, 2018;
  • Mandatory reporting of sales information related to MIA; and
  • New requirements and the expansion of the Veterinary Health Products (VHP) Notification Program to increase access to products for production animals.

More information about these regulatory and policy changes can be found on the Health Canada website.  Questions about the regulatory and policy changes should be sent to

More information about updates being made to the Compendium of Medicating Ingredient Brochures (CMIB) can be found on the Canadian Food Inspection Agency website. Questions about these updates should be sent to your local CFIA office.

Along with Health Canada, CAHI collaborated with the Canadian Veterinary Medical Association (CVMA) and the Animal Nutrition Association of Canada (ANAC) to help raise awareness of these changes. 

  • Veterinarians should refer to the CVMA website for additional materials
  • Health Canada and the Canadian Food Inspection Agency have created some tools to assist veterinarians when writing feed prescriptions. The use of these templates is optional.
  • The ANAC fact sheet detailing how these changes are managed in the Compendium of Medicating Ingredient Brochures can be found here

Responsible Use Logo

Contains Antimicrobial. Use Responsibly.

CAHI is pleased to share the “Contains Antimicrobial, Use Responsibly” logo for voluntary use on Category I, II, and III medically important antimicrobials used in animals by our members.

We recognize the importance of taking action to mitigate antimicrobial resistance and created this logo to:

  • Facilitate easy recognition of medically important antimicrobial products by veterinarians and animal care providers through product labels, inserts and brand promotions.
  • Prepare a simple, easily understood message about the importance of responsible use of these medications by veterinarians and animal care providers.

The logo helps CAHI and its members to communicate the following key responsible use messages:

  • Medically important antimicrobials need to be used responsibly in animals to best manage potential resistance in humans and animals.
  • When resistance occurs it diminishes our ability to treat disease effectively, in both animals and humans.
  • We care about animal welfare and the use of antimicrobials empowers veterinarians and farmers who want to keep animals healthy and well cared for.
  • We all have a role in minimizing resistance and safeguarding the effectiveness of antimicrobials.
  • Everyone must to do their part to prescribe, dispense and use antimicrobials responsibly.
