An outbreak of hepatitis A involved more than 50 residents of a group of villages in the late spring and summer of 1989. The only food that was common to all the laboratory-confirmed cases was bread, purchased either unwrapped or as rolls, sandwiches or filled rolls, and supplied either directly from one shop or indirectly through its subsidiary outlets. It was concluded that this bread was the most likely vehicle of transmission of the hepatitis A virus and that the bread was contaminated by soiled hands which were inadequately washed because of painful skin lesions. Comprehensive control measures were successful in limiting further spread of the infection. This outbreak highlights the transmissibility of hepatitis A virus on food. The use of disposable gloves when handling food which is to be consumed without further cooking would prevent transmission of this or other infectious agents by this route.
1989年春末夏初，一组村庄中有50多名居民爆发了甲型肝炎。所有实验室确诊病例唯一共同食用的食物是面包，这些面包要么是未包装的，要么是做成面包卷、三明治或夹馅面包卷的，要么直接从一家商店供应，要么通过其附属分店间接供应。得出的结论是，这种面包最有可能是甲型肝炎病毒的传播媒介，而且面包被因皮肤病变疼痛而未充分清洗的脏手污染了。综合控制措施成功地限制了感染的进一步传播。这次疫情突出了甲型肝炎病毒在食物上的传播性。在处理无需进一步烹饪即可食用的食物时使用一次性手套，将防止通过这种途径传播这种或其他传染源。
