Abstract

Salmonella senftenberg and Salmonella typhimurium survived the production of gelatin sheets containing nutrient broth although there was some evidence of cell damage. Both strains survived but did not grow in glassy states with an a(w) of 0.45-0.28 and rubbery states with an a(w) of 0.93-0.96 for at least 28 d. Survival was less in intermediate states with an a(w) between 0.55 and 0.74. The results suggest that salmonellas should be excluded from glassy state products in order to prevent salmonellosis.

森夫腾堡沙门氏菌和鼠伤寒沙门氏菌在明胶玻璃状和橡胶状状态下的存活。
senftenberg沙门氏菌和鼠伤寒沙门氏菌在含有营养肉汤的明胶片的生产中存活,尽管有一些细胞损伤的证据。在a(w)为0.45 ~ 0.28的玻璃态和a(w)为0.93 ~ 0.96的橡胶态下,两种菌株均存活,但至少28 d没有生长。在a(w)为0.55 ~ 0.74的中间态下,两种菌株的存活率较低。结果表明,为了预防沙门氏菌病,应从玻璃状态产品中排除沙门氏菌。
