Globally, Hepatitis E virus (HEV) causes over 20 million cases worldwide. HEV is an emerging and endemic pathogen within economically developed countries, chiefly resulting from infections with genotype 3 (G3) HEV. G3 HEV is known to be a zoonotic pathogen, with a broad host range. The primary source of HEV within more economically developed countries is considered to be pigs, and consumption of pork products is a significant risk factor and known transmission route for the virus to humans. However, other foods have also been implicated in the transmission of HEV to humans. This review consolidates the information available regarding transmission of HEV and looks to identify gaps where further research is required to better understand how HEV is transmitted to humans through food.

在全球范围内，戊型肝炎病毒 (HEV) 导致全球超过 2000 万例病例。HEV 是经济发达国家的一种新出现的地方性病原体，主要由基因型 3 (G3) HEV 感染引起。众所周知，G3 HEV 是一种人畜共患病原体，宿主范围广泛。在经济较发达的国家，HEV 的主要来源被认为是猪，而猪肉产品的消费是该病毒向人类传播的重要风险因素和已知传播途径。然而，其他食物也与 HEV 向人类传播有关。本综述整合了有关 HEV 传播的可用信息，并试图找出需要进一步研究以更好地了解 HEV 如何通过食物传播给人类的差距。
