摘要：

From March to November 2000, 170 samples of smoked fishy and 182 samples of pate for sale in retail outlets and supermarkets in the nine provinces of Castilla and Leon (Spain) were analyzed for the prevalence of Listeria monocytogenes and other Listeria spp. L. monocytogenes was isolated from 38 (22.3%) of the 170 samples of smoked fish analyzed. Twenty of these positive samples contained L. monocytogenes. at > 100 CFU/g. Other Listeria spp., such as Listeria innocua (26 isolates), Listeria grayi (9), Listeria welshimeri (3), Listeria seeligeri (3), and Listeria ivanovii (2), were also detected. L. monocytogenes was isolated front 5.4% of the 182. samples of pate. Only 1 of the 10 positive samples harbored > 100 L. monocytogenes CFU/g. Two other species of Listeria were observed in pate. L. innocua (12 isolates) and L. grayi (2).
