Abstract

Roast beef, turkey breast, pastrami, corned beef and pickle and pimento loaf were obtained from delicatessens in eight Gainesville (FL) supermarkets. A total of 80 samples were analyzed for total aerobic counts (APC at 35 and 20 C), yeasts and molds, fecal streptococci, Staphylococcus aureus , Clostridium peifringens , total coliforms, fecal coliforms, Escherichia coli and Salmonella . No Salmonella was recovered from any samples and only one sample contained C. peifringens . S. aureus was recovered from 12.5% of the samples at levels less than 1 log/g and E. coli was found in 11.3% of the samples. All samples contained fecal streptococci and 73.8% contained coliforms. APCs (35 C) were highest in corned beef and pastrami samples with mean counts of 6.75 and 6.91 logs/g, respectively; roast beef samples had lowest APCs with a mean count of 4.84 logs/g. High APCs and coliform counts in many samples indicate a need for improved sanitation procedures at the processor and retail levels.

摘要

烤牛肉、火鸡胸肉、五香熏牛肉、咸牛肉以及腌黄瓜和甜椒肉糕均取自佛罗里达州盖恩斯维尔市八家超市的熟食店。总共80个样本接受了分析，检测项目包括总需氧菌数（35℃和20℃下的APC）、酵母菌和霉菌、粪链球菌、金黄色葡萄球菌、产气荚膜梭菌、总大肠菌群、粪大肠菌群、大肠杆菌和沙门氏菌。所有样本均未检出沙门氏菌，仅一个样本含有产气荚膜梭菌。12.5%的样本检出金黄色葡萄球菌，含量低于1 log/g，11.3%的样本检出大肠杆菌。所有样本均含有粪链球菌，73.8%的样本含有大肠菌群。咸牛肉和五香熏牛肉样本的35℃下总需氧菌数最高，平均计数分别为6.75和6.91 log/g；烤牛肉样本的总需氧菌数最低，平均计数为4.84 log/g。许多样本中总需氧菌数和大肠菌群数较高，表明在加工和零售层面需要改进卫生程序。
