摘要
The microbiological effects of three operations for cleaning areas on dressed beef carcasses with vacuuming equipment which also applies hot water to the carcass, and of an operation for pasteurizing beef carcass sides with steam, were assessed. All four operations were routine in a commercial carcass dressing process. For each operation, swab samples were obtained from randomly selected carcasses, with a single sample being collected from each carcass, from a site selected at random from those affected by the operation. For the cleaning operations, 25 samples were obtained before and 25 after each operation. For the pasteurizing operation, 50 samples were obtained before and 50 after the operation. In addition, 50 samples were obtained from beef sides after the carcass cooling process which followed the pasteurizing operation. Total aerobic counts, coliforms and Escherichia coli from each sample were enumerated. The cleaning operations generally reduced the log mean numbers of bacteria on treated areas by less than or equal to 0.5 and had no discernible effect on the overall microbiological condition of the carcasses emerging from the process, The pasteurizing operation reduced the log mean numbers of total aerobic bacteria on carcasses by about I, and the log mean numbers of coliforms and E. coli by > 2. The cooling process had no affect on the total counts, but further reduced the log mean numbers of coliforms and E. coli, apparently by about 1, to give beef sides from which E. coli were not recovered.
