coli) and the incidence rate of human infection with ceftiofur-resistant Salmonella Heidelberg was calculated as described in CIPARS 2006 annual report (12).
Ceftiofur-resistant Salmonella Heidelberg has never been reported among CIPARS porcine Salmonella of abattoir origin, and it has not been detected among retail pork, abattoir beef, or retail beef, in which Salmonella prevalence remains <2% (12).
Again, CIPARS data from Quebec retail chicken sampling in 2007-2008 demonstrating a reemergence of ceftiofur resistance among E.
CIPARS data clearly indicate a temporal association between changing levels of contamination of retail chicken with ceftiofur-resistant Salmonella Heidelberg strains and incidence of ceftiofur-resistant Salmonella Heidelberg infection in humans.
Lastly, CIPARS is planning a burden-of-illness study to measure the impact of extended-spectrum cephalosporin resistance in Salmonella Heidelberg on human health.

Dr Dutil passed away suddenly in August 2011 and is sadly missed by CIPARS and all who worked with her.
Molecular investigations of organisms isolated from retail chicken by CIPARS have yet to be conducted.
CIPARS collects raw, fresh (never frozen) chicken primarily produced and distributed in Canada.
The broiler industry is collaborating with CIPARS to create a farm surveillance program, which would capture data on antimicrobial drug use and resistance.
