本文调查六种食品257份蜡状芽胞杆菌平均污染率为41．2％，达到中毒标量14份；生物分型主要为生物2型及8型；该菌对多数抗生素敏感，其毒力强弱与活菌量密切相关；它耐热力较强，煮沸25min及热压110C5min尚不能全部杀死，但煮沸10min所杀灭的活菌量及破坏的肠毒素足以预防本菌?
In this paper, the average contamination rate of 257 Bacillus cereus of six kinds of foodstuffs was investigated, which reached 41.2%, reached 14 poisoning scalings; the biological types were mainly biological type 2 and 8; the bacteria were sensitive to most antibiotics and their virulence Closely related to the amount of viable bacteria; it is strong heat resistance, boiling 25min and hot 110C5min still can not kill, but boil 10min kill live bacteria and destruction of enterotoxin enough to prevent the bacteria?
