One hundred and four samples of various imported meats obtained from the stores and supermarkets in Matsuyama-city and Iyo-city from November, 1987 to October, 1988 were examined and two strains of Vero toxin-producing Escherichia coli were isolated: one was from beef from Australia and the other was from pork from Canada. By bead-ELISA, it was confirmed that the strain from beef produced Vero Toxin 1 (VT1) and Vero Toxin 2 variant (VT2vh) and the strain from pork produced VT2vh. These results suggest that imported meats may be contaminated with VTEC and thus are possible sources of human VTEC infection, such as hemorrhagic colitis and hemolytic uremic syndrome.
1987年11月至1988年10月期间，从松山市和伊予市的商店及超市采集了104份各类进口肉类样本进行检测，分离出两株产志贺毒素大肠杆菌：一株来自澳大利亚牛肉，另一株来自加拿大猪肉。通过珠式酶联免疫吸附测定法（bead-ELISA）证实，来自牛肉的菌株产生志贺毒素1（VT1）和志贺毒素2变体（VT2vh），来自猪肉的菌株产生VT2vh。这些结果表明，进口肉类可能被产志贺毒素大肠杆菌污染，因此可能是人类产志贺毒素大肠杆菌感染（如出血性结肠炎和溶血性尿毒症综合征）的传染源。
