Antimicrobial Stewardship

The Canadian feed industry recognizes the importance of using antimicrobials responsibly while ensuring optimal animal health and welfare. Nutrition plays a key role in achieving this balance and ANAC is working in collaboration with government and industry partners on several aspects of antimicrobial stewardship.

Fact sheets on the policy changes

Antimicrobial Policy Change: As of December 1, 2018 all category I, II and III antimicrobials will be on Health Canada's Prescription Drug List.  This Fact Sheet addresses common questions from the feed industry related to this policy change.

On December 1, 2018, as a result of a policy change, all Medically Important Antimicrobials (MIAs; ie those in Category I, II, and III) will be published on Health Canada’s Prescription Drug List. Consequently, a veterinary prescription will be required for producers to purchase these antimicrobials as of that date.

Antimicrobials Requiring a Veterinary Prescription as of December 1, 2018 (PDF): A poster has been developed with a  list of the antimicrobials, by brand name, affected by the policy change (Category I to III antimicrobials).

Transition to and Implementation of the ‘New’ CMIB (PDF): A new CMIB will be published on April 1, 2018 to align with the policy changes coming into effect December 1, 2018. For information on the use of the old and new CMIB during this transition period, a factsheet has been developed.

Managing Inventory during the transition period (PDF): Commercial feed mills and retail outlets will need to manage their antimicrobial inventory carefully leading up to December 1, 2018. Read the Canadian Animal Health Institute and ANAC’s statement on.

Sales and Dispensing of prescription DIN drug premixes* and prescription medicated feed (PDF): Producers will only be able to purchase their Pr DIN Drug Premixes, to manufacture their own feed on farm, from veterinarians or pharmacists pursuant to a veterinary prescription (with the exception of Quebec).

Health Canada Fact Sheet on Accessing and Selling Prescription Veterinary Drugs (PDF): This fact sheet explains the federal rules on how prescription (Pr) drugs (in dosage form) can be accessed and sold in Canada – it does not apply to the non-prescription drug context. It also does not allow for the sale of medicated feed containing prescription products to be sold through dealer networks, which would have significant detrimental impacts on businesses and is a policy that has since been revised. A supplementary document was later published, Health Canada Fact Sheet on Selling Prescription Medicated Feed addressing some practical applications and common questions related to sales of medicated feed containing prescription products via dealer networks. 

Resolution on dealer networks selling medicated feed containing prescription drugs (PDF): This fact sheet addresses practical applications of the dealer resolution, and answer common questions related to the December 1st, 2018 policy change.

Veterinary prescription templates

Health Canada, the Canadian Food Inspection Agency and ANAC have developed tools to help ensure that veterinary feed prescriptions are consistent and compliant with Canadian regulations. The use of the templates is optional.
