食品のサルモネラ属菌検査におけるRambaQUICK Salmonellaの評価

抄録

The preliminary results indicated that the RambaQUICK Salmonella (RQS), a new rapid selective enrichment broth, was possible to support the growth of all tested strains of four Salmonella Enteritidis and one S. Typhimurium, and inhibited the growth of all tested non-Salmonella microorganisms. Furthermore, we compared the performance of the two enrichment methods, Rappaport-Vassiliadis selective enrichment followed Buffered peptone water pre-enrichment (BPW-RV) method and RQS selective enrichment from BPW (BPW-RQS) method, using 224 of routine samples suspected Salmonella spp polution. and 58 samples of retail chicken meats. Of 282 samples tested, the detection rate of BPW-RQS method for Salmonella spp. (63.8%; 37/58) was higher than BPW-RV method (31.0%; 18/58) in retaile chicken meats, and 224 were negative by both methods in routine samples. It is summarized that BPW-RQS method make possible the identification of Salmonella within the 2 days, then the results of Salmonella could inform as the quality control data attached with viable counts, coliforms, and Staphylococcus aureus. From these results, we concluded that BPW-RQS method was useful for the quality control work flow in the laboratory of food industry.
