Canada has not taken action against existing loopholes (“own use”, “active pharmaceutical ingredients”,<br />
importing) associated with widespread use of antimicrobials in farmed animals. Canada should require<br />
veterinary prescriptions for these drugs, and should end large-scale importation of these un-prescribed<br />
drugs for farmers’ “own use” in animals.<br />
In December 2013, the U.S. Food and Drug Administration announced restricted use of antibiotics as<br />
growth promotants for farmed animals, including poultry. Antimicrobial drugs will require a prescription<br />
from a licensed veterinarian to treat, prevent or control disease. The USDA intends to phase in the new<br />
restrictions over three years. 86<br />
Canada should follow the lead of the U.S. Food and Drug Administration in requiring veterinary<br />
prescriptions for valuable antimicrobial drugs.<br />
Examples of antimicrobial drugs registered for use in animals and humans in Canada; Drugs registered<br />
for disease prevention, prophylaxis and/or control in chickens:<br />
Lasolocid sodium (coccidiosis)<br />
Maduramicin (coccidiosis)<br />
Monensin (coccidiosis)<br />
Narasin (coccidiosis)<br />
Salinomycin sodium (coccidiosis)<br />
Bacitracin 87<br />
