Foodborne viruses are becoming a global concern as they overwhelm the health system and have the potential to spread globally. Among them, some genotypes of hepatitis E virus (HEV), which is one of the main causes of acute hepatitis in humans, have a zoonotic potential and can be found in foods of animal origin. Infected farm animals are a possible source of the virus, either by direct contact with animal excreta or meat. In the present study, 240 bovine liver samples from slaughter carried out in Rio Grande do Sul (RS), Brazil, were analyzed and tested for the presence of HEV. After performing PCR, 5.4% of positive samples were observed. One of the samples could be identified by molecular phylogenetic analysis as belonging to genotype 3, for which pigs are natural reservoirs, but has not been reported in bovine meat and products so far.
食源性病原体日益受到全球关注，因为它们对卫生系统造成冲击，并可能在全球范围内传播。其中，一些基因型的戊型肝炎病毒（HEV）是人患急性肝炎的主要病因之一，具有动物源性病原体特性，可能存在于动物源性食品中。受感染的农场动物可能是病毒的潜在传染源，其传播途径可能是直接接触动物粪便或肉类。在本研究中，对巴西南里奥格兰德州（RS）屠宰的 240 份牛肝样本进行了分析并检测了 HEV 的存在情况。通过 PCR 检测，观察到 5.4%的阳性样本。通过分子系统进化分析，其中一个样本被鉴定为基因型 3，该基因型的天然宿主是猪，但目前尚未在牛肉和牛肉制品中报告过。
