To determine whether chicken livers infected with Campylobacter jejuni are seeded in vivo or contaminated after slaughtering, 117 livers purchased in retail outlets in New York were examined for surface and tissue infections. Of 56 livers positive for C. jejuni, 36 yielded surface growth only, 18 both surface and tissue growth, and 2 tissue growth only. The scanty growth from tissue samples suggests a carry-over of organisms from the surface. It was concluded, therefore, that contamination is most likely due to unhygienic handling of offal. Infection rates of livers varied from retailer to retailer.
为了确定感染空肠弯曲菌的鸡肝是在体内被接种的还是在屠宰后被污染的,对在纽约零售商店购买的117个鸡肝进行了表面和组织感染检查。在56个空肠弯曲菌呈阳性的鸡肝中,36个仅表面生长,18个表面和组织均生长,2个仅组织生长。组织样本中生长稀少表明微生物是从表面残留的。因此得出结论,污染很可能是由于内脏处理不卫生所致。鸡肝的感染率因零售商而异。
