Résumé

AbstractSix to seven consecutive sanitary surveys were conducted in five different Canada Approved meat packing plants and slaughterhouses in order to establish the level of bacterial contamination on working surfaces as well as on surfaces of slaughtered animals (chicken and beef) during their processing. The various microbiological parameters evaluated were total aerobic plate count at 22 and 35C, total and fecal coliforms, fecal streptococci, molds and yeasts and Salmonella. A total of 634 samples was collected at different critical control points during these sanitary surveys in 197677. Contamination of the working surfaces in various plants varied from 106 to 108/77cm2(12 in2) for the total aerobic plate count at 22 and 35C; 104 to 105 for yeasts and molds; 103 to 105 for total coliform and 103 for fecal streptococci, while only a few fecal coliform and Salmonella were isolated. Samples at the broiler plant showed an initial level of Salmonella of 76.9%.Surfaces of beef carcasses at the packing plants were also monitored; the total aerobic plate counts fluctuated from 1O4 to 109/77cm2. This high level of contamination could contribute to the high bacterial counts on the working surfaces. At time of sampling, every plant was inspected, the results of the latest sanitary survey discussed, and improved cleaning and disinfection techniques were suggested. The level of contamination was reduced considerably, as evidenced after the final sanitary survey which showed a 1,000 fold decrease in total aerobic plate counts. Salmonella positives decreased to 4.5% at the broiler slaughtering plant. We can conclude from this work that it is possible, with good manufacturing practices and appropriate cleaning and sanitizing procedures, to maintain low microbial levels on equipment and working surfaces.
