Hepatitis E virus (HEV) and Salmonella bacteria are zoonotic pathogens that can be acquired by foodborne transmission because food animals, for example pigs, are recognized as a reservoir. The objectives of this study were to determine the seroprevalence of anti-HEV immunoglobulin G (IgG) and anti-Salmonella antibodies from healthy pigs at slaughter in Switzerland, a country with a good health status of pig herds (e.g., eradication of enzootic pneumonia) compared with those of many countries in the European Union, and a rate of importation of live pigs that is very low (<1%). Based on pooled (diaphragm muscles from 3 to 5 animals per producer) meat juice samples, 120 (60%) of 200 and 8 (4%) of 200 samples were positive for anti-HEV IgG and anti-Salmonella antibodies, respectively. HEV seems to be highly prevalent among fattening pigs in Switzerland, whereas the low seroprevalence of anti-Salmonella IgG has not changed in recent years.
戊型肝炎病毒 (HEV) 和沙门氏菌是食源传播的人畜共患病原体，因为猪等食用动物被认为是这些病原体的储存宿主。本研究的目的是确定瑞士屠宰健康猪的抗 HEV 免疫球蛋白 G (IgG) 和抗沙门氏菌抗体的血清阳性率。与欧盟许多国家相比，瑞士猪群的健康状况良好（例如，消灭地方性肺炎），活猪进口率非常低（<1%）。基于汇总（每个生产者的 3 至 5 头动物的膈肌）肉汁样本，200 个样本中分别有 120 个（60%）和 8 个（4%）对抗 HEV IgG 和抗沙门氏菌抗体呈阳性。HEV 在瑞士育肥猪中似乎高度流行，而近年来抗沙门氏菌 IgG 的低血清阳性率并未改变。
