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.

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.
