Between 1992 and 2000, 1,518 foodborne general outbreaks of infectious intestinal disease (IID) were reported to the Public Health Laboratory Service (PHLS) Communicable Disease Surveillance Centre (CDSC), of which 83 (5.5%) were associated with the consumption of salad vegetables or fruit (SVF). The pathogens most frequently reported were salmonellas (41.0%) and Norwalk-like virus (NLV) (15.7%). In total 3,438 people were affected; 69 were admitted to hospital and one person died. Most outbreaks were linked to commercial catering premises (67.5%). Three community outbreaks, of Salmonella enterica serovar Typhimurium Definitive Phage Type (DT) 104, S. Typhimurium DT 204b and Shigella sonnei infection, were found to be associated with lettuce contaminated at source, and these accounted for 501 (14.6%) cases. The latter two outbreaks were international, involving several European countries. This demonstrates how contamination of SVF during production/processing can result in major, geographically widespread, outbreaks of infection with serious public health consequences.
1992年至2000年间，公共卫生实验室服务处（PHLS）传染病监测中心（CDSC）共收到1518起食源性感染性肠道疾病（IID）群发事件报告，其中83起（5.5%）与食用沙拉蔬菜或水果（SVF）有关。最常报告的病原体是沙门氏菌（41.0%）和诺如病毒（NLV）（15.7%）。共有3438人受到影响；69人住院，1人死亡。大多数疫情与商业餐饮场所有关（67.5%）。发现三起社区疫情，分别由肠炎沙门氏菌鼠伤寒亚种噬菌体定型（DT）104型、鼠伤寒沙门氏菌DT 204b型和宋内志贺氏菌感染引起，与源头受污染的生菜有关，这些疫情导致了501例（14.6%）病例。后两起疫情是国际性的，涉及几个欧洲国家。这表明SVF在生产/加工过程中的污染如何导致重大的、地域广泛的感染疫情，并产生严重的公共卫生后果。
