摘要：

Interior muscle cores from 50 beef, 50 pork, and 10 lamb roasts, purchased at retail, were assayed for Listeria ssp., which was isolated from three beef roasts and three pork roasts, but not from lamb roasts. Five isolates of serotype la Listeria monocytogenes were obtained from the roasts, together with one strain each of Listeria innocua and Listeria welshimeri. Twice, L. monocytogenes was present at 10 CFU/ g; all other isolations of Listeria spp. required enrichment (<10 CFU/ g). The presence of listeriae in cores of whole‐muscle meat roasts is probably not a result of environmental contamination, and may be due to antemortem exposure of the animal to Listeria.
