Possible Seasonality of Clostridium difficile in Retail Meat, Canada
Figure 1. Distribution of retail grocery stores sampled (n = 210) and proportion with contaminated meat. The overall proportion of stores with >1 meat package contaminated with Clostridium difficile was 5.7%. No statistical differences were observed when comparing the proportions of ground beef contamination in Québec, Ontario, and Saskatchewan, Canada (p>0.2). No comparisons for veal chops were made because Québec was the main source of this commodity; veal from milk-fed calves was not available in Saskatchewan, and only 3 stores had this type of veal during sampling in Ontario.
