Résumé

The purge from beef combos (a mixed collection of beef trimmings) was tested as a means of representatively sampling the microbial content of this raw product. In the first experiment, purge was sampled from model beef combos that has been innoculated with bovine feces. Data from this experiment indicated a strong correlation (r= 0.94) between the total aerobic bacteria counts derived from the purge samples of a model beef combo and the total aerobic bacteria present in a rinse sample of the entire model beef combo. Other experiments are described and their results confirm that a purge sample from a beef combo is a more efficacious sampling method for determining the general bacterial profile of coliforms and E. Coli than randomly taken core samples.
