Analysis excluded flocks which were intentionally raised without antibiotics under designated programs for mainstream market such as “Raised without Antibiotics,” “Antibiotic-Free,” and organic.

CIPARS—Canadian Integrated Program for Antimicrobial Resistance Surveillance.

^(CIPARS)Based on routine CIPARS formula.

^(ALT)kg turkey live pre-slaughter weights, alternate estimation methods.

nDDDvetCA—number of defined daily doses for animals using Canadian standards.

PCU—population correction unit (based on the European Surveillance for Veterinary Antimicrobial Consumption average weight at treatment for turkeys at 6.5 kg).

Tk—turkeys.
