Research Note: Assessment of the Microbiological Conditions of Tails, Tongues, and Head Meats at Two Beef-Packing Plants

摘要

Newly skinned tails of beef carcasses at two packing plants were similarly contaminated with total aerobes and with coliforms that were largely Escherichia coli at log mean numbers about 3.5/cm~2 and 4.5/100 cm~2, respectively. The log mean number so aerobes and coliforms on the skinned tails after washing at plant A were, respectively, 1 and 2 log units less than the numbers on the newly skinned tails. At plant B, the log mean numbers of aerobes on skinned and on washed tails were similar while the log mean numbers of E. Coli on washed tails were only about 1 long unit less than the numbers on skinned tails.
