Almost all cases of human listeriosis are foodborne, however the proportion where specific exposures are identified is small. Between 1981 and 2015, 5252 human listeriosis cases were reported in England and Wales. The purpose of this study was to summarise data where consumption of specific foods was identified with transmission and these comprised 11 sporadic cases and 17 outbreaks. There was a single outbreak in the community of 378 cases (7% of the total) which was associated with pâté consumption and 112 cases (2% of the total) attributed to specific foods in all the other incidents. The proportion of food-attributed cases increased during this study with improvements in typing methods for Listeria monocytogenes. Ten incidents (one sporadic case and nine outbreaks of 2-9 cases over 4 days to 32 months) occurred in hospitals: all were associated with the consumption of pre-prepared sandwiches. The 18 community incidents comprised eight outbreaks (seven of between 3 and 17 cases) and 10 sporadic cases: food of animal origin was implicated in 16 of the incidents (sliced or potted meats, pork pies, pâté, liver, chicken, crab-meat, butter and soft cheese) and food of non-animal origin in the remaining two (olives and vegetable rennet).
几乎所有人类李斯特菌病病例都是食源性的，但确定具体暴露源的比例很小。在 1981 年至 2015 年期间，英格兰和威尔士报告了 5252 例人类李斯特菌病病例。本研究的目的是总结已确定特定食品消费与传播之间关系的数据，这些数据包括 11 例散发病例和 17 例暴发。有一起涉及 378 例（占总数的 7%）的社区暴发与肉酱消费有关，另有 112 例（占总数的 2%）归因于所有其他事件中特定食品。随着李斯特菌属分型方法的改进，食源性病例的比例在本研究期间有所增加。有 10 起事件（1 例散发病例和 9 起暴发事件，涉及 2-9 例病例，持续时间为 4 天至 32 个月）发生在医院：均与食用预制三明治有关。18 起社区事件包括 8 起暴发（7 起暴发涉及 3-17 例病例）和 10 例散发病例：16 起事件涉及动物源性食品（切片或罐装肉、猪肉馅饼、肉酱、肝脏、鸡肉、蟹肉、黄油和软奶酪），其余两起事件涉及非动物源性食品（橄榄和植物凝乳酶）。
