引起食物中毒绿豆糕的霉菌检验分析

Examination of Molds to Greenbean Cake Causing Human Toxicosis

引起多起食物中毒的绿豆糕有霉变现象，绿豆糕中的霉菌和酵母菌总数，在虎红培养基上为１１０００ＣＦＵ／ｇ，在高盐蔡氏培养基上为２２０００ＣＦＵ／ｇ，霉菌相主要由扩展青霉和阿姆斯特丹散囊菌组成。经卤虫急性毒性试验法测定，两种分离的霉菌都是产毒菌株。文中还对这类霉菌和霉菌毒素引起的食物中毒特点进行了讨论。

A batch of green - bean cake causing human toxicosis have some moldy features. The molds and yeasts count of the cake was 11000 CFU/g in rosy bengal chloramphenicol agar plate and was 22000CFU/g in high salt Czapek Dox agar plate. The my-coflora was chiefly made of Penicillium expansum and Eurtium amstelodami. The isolates of P. expansum and E. amsteloda-mi were all toxigenic strains by Artimia salina bloassay. The toxicosis features of these molds and mycotoxins were also anal ysed.
