北京部分市售整雞中沙門菌和彎曲菌協(xié)同定量污染研究
[Abstract]:Objective to study the quantitative contamination levels of Salmonella and Campylobacter, the distribution of Salmonella serotype and campylobacter species in some chicken samples sold in Beijing in 2013. Methods 33 chicken samples were collected from Beijing from May to July, 2013. Salmonella and Campylobacter in the samples were detected quantitatively, and the serotyping and species identification of Salmonella and Campylobacter were carried out respectively. Results Salmonella was detected in 19 samples, and campylobacter was detected in 5 samples. The average contamination levels of Salmonella and Campylobacter in positive samples were 119.4 MPN/100g and 58.6 CFU / g, respectively. 166 strains of Salmonella were identified as 14 serotypes, the most common of which was Salmonella enteritidis, followed by Indiana Salmonella. A total of 11 different serotype combinations of Salmonella were isolated from the same sample. The most common serotype combination was Salmonella enteritidis. Conclusion the contamination rate of salmonella is high, the pollution level is serious, and the serotype is complex in some whole chickens sold in Beijing from May to July 2013.
