The objectives of this study were to determine the prevalence of antimicrobial resistance among E. coli and Salmonella from smallholder chickens slaughtered in provincially inspected abattoirs in Ontario, and to make comparisons with results from CIPARS abattoir component.

A list of provincially inspected abattoirs (n = 18) that process smallholder chickens, located within a 3-hr driving radius of Guelph, Ontario, were invited to participate. Sampling was conducted between May and September in 2014 and 2015 during the main smallholder flock production season. During each sampling visit, five non-sequential viscera samples were collected from five chickens belonging to one flock and placed into individual leak-proof zipper bags. Caeca were separated out from the viscera upon arrival to the laboratory and caecal contents aseptically extracted.
