Quantitative analyses of Listeria monocytogenes in imported ready-to-eat (RTE) foods sold at retail stores in Japan were performed. Of the 77 non-cooked meat products, 6 samples (7.8%) tested positive. The levels of contamination of 4 of the samples were below 100 colony-forming units (CFU)/g, which is the microbiological criterion for L. monocytogenes in RTE foods as determined by Codex. However, Listeria cells at levels of 100 and 400 CFU/g were detected in a salami sample and a raw ham sample, respectively. All of the 70 cheese samples and the 3 samples made from raw ham and cheese showed negative test results. These results suggest that imported RTE foods are potential sources of the causative agent of listeriosis.
