Altogether 150 samples of vacuum-packed fish were examined for the presence of Listeria species. Listeria monocytogenes were isolated from 12 of 58 'gravad' fish samples, 3 of 26 cold-smoked and one of 66 hot-smoked fish samples. Ten of these 16 positive samples harboured more than 100 L. monocytogenes cfu/g. The highest level (132,000) was found in a sample of hot-smoked rainbow trout (Oncorhynchus mykiss). Serogroup 1/2 was most frequently found, followed by 4 and 3. One sample of gravad rainbow trout harboured more than one serogroup of L. monocytogenes. L. innocua and L. seeligeri were isolated from 12 and 1 samples, respectively.
共检测了150份真空包装鱼样本中李斯特菌属的存在情况。在58份“腌制”鱼样本中的12份、26份冷熏鱼样本中的3份以及66份热熏鱼样本中的1份中分离出了单核细胞增生李斯特菌。这16份阳性样本中有10份每克含有超过100个单核细胞增生李斯特菌菌落形成单位。最高水平（132,000）出现在一份热熏虹鳟鱼（Oncorhynchus mykiss）样本中。血清群1/2最为常见，其次是血清群4和3。一份腌制虹鳟鱼样本中含有不止一个血清群的单核细胞增生李斯特菌。无害李斯特菌和斯氏李斯特菌分别从12份和1份样本中分离出来。
