Comparison of Russian and United States official methods of analysis of poultry for Salmonella.

摘要

Laboratory tests to compare the official analytical methods for detection of Salmonella in poultry from Russia and the United States were conducted within the framework of the US-Russian Poultry Safety Consulting Center. Samples of ground poultry meat (poultry mince), both inoculated and non-inoculated with Salmonella, were analysed. The samples were coded so that the researchers did not know the status of each sample. The samples were tested by 2 teams of researchers, each including representatives of the US and Russian parties. Each team received a set of 50 samples, of which 20% were inoculated with Salmonella spp. at a population of 3-25 cfu/g. The official methods of the 2 countries were very similar in many respects. Based on the testing of positive (test) and negative (control) samples, it was demonstrated that the methods were not statistically different with this sample set and both methods correctly identified all inoculated samples, with no false positive or false negative samples detected.
