中文摘要：本研究调查了巴西三个花生糖加工企业(A、B和C)的肠杆菌科细菌、大肠菌群、大肠杆菌和沙门氏菌污染的情况。结果表明生产环境，包括食品加工人员可能是花生糖主要的污染源。本研究首次调查了贯穿花生糖加工生产线中沙门氏菌和其他肠杆菌科细菌的污染情况。结果可用于协助风险评估研究并制定更有效的控制措施。
外文摘要：AIMS: In order to investigate Enterobacteriaceae, coliforms, Escherichia coli, and Salmonella contamination a survey was conducted at three peanut confectionery processing companies (A, B, and C) in Brazil. METHODS AND RESULTS: Samples of different peanut confectionery products (n=59), peanut raw material (n=30), manufacturing environment (n=116), and workers' hand surfaces (n=12) were analyzed. Salmonella and E. coli were not detected in any final product or raw material analyzed. Enterobacteriaceae was isolated from 15 % of final products. Coliforms were detected in only one sample. Referring to the raw material, six samples showed contamination by Enterobacteriaceae and three samples by coliforms. For the process environment, 19 % and 11 % of samples presented Enterobacteriaceae and coliforms. E. coli was detected in 5 % of samples, and one of these samples tested positive for Salmonella; this strain was serotyping as S. Heidelberg. All food handlers surveyed in Company C showed Enterobacteriaceae and coliforms on their hands. E. coli was isolated from one food worker's hand. CONCLUSION: The results showed that the manufacturing environment, including food handlers were considered the main sources for possible contamination of peanut confectionery products. SIGNIFICANCE AND IMPACT OF STUDY: This has been the first study to investigate the occurrence of Salmonella and other Enterobacteriaceae throughout peanut confectionery processing lines. The results might be used to assist risk assessment studies and to establish more effective control measures.
