HEAT RESISTANCE OF Yersinia enterocolitica IN SKIM MILK

摘要

ABSTRACTThis report presents information on the heat resistance in skim milk ofY. enrerocoliticastrains isolated from vacuum‐packaged meat and of two ATCC cultures. Data indicate considerable variation existed in the heat resistance of the test cultures, with ATCC cultures 23715 and 9610 being more heat resistant at 50 to 60°C than cultures isolated from vacuum‐packaged beef. Culture 1049 was the least heat resistant. Data suggest that few if any survivors can be expected in foods heated and/or kept above 60°C for several mi
