Abstract

A total of 139 samples including 29 pork, 21 chicken, 19 beef, 17 mutton, 18 chicken's egg, 10 duck's egg, 20 fish and 5 seafood samples were collected from the market in Hebei province of China in 2009-2010. These foods were examined for the presence of Salmonellae by cultural methods and biochemical tests. The isolates were characterized using serotyping testing. The 9 (6.9%) of 139 samples were positive for Salmonella, the most common serovar being Salmonella typhimurium (6/9). The positive rates of eggs, fish, chicken, pork andbeefwere 11.1 (2), 10(2), 9.5 (2), 6.9 (1) and5.3% (1), respectively. Salmonella paratyphi (1) and Salmonella choleraesuis (2) were also isolated. All other products were negative. Results from these studies could form a basis for risk assessment and future interventions which intended to reduce the incidence of Salmonella in Hebei province of China and potential hazards from antimicrobial resistance in Salmonella.© Medwell Journals.2012.
