Prevalence of Salmonella in retail chicken meat in Hanoi, Vietnam.
Infection with Salmonella (S.) is the most frequently reported cause of bacterial food-borne illness worldwide. Poultry are a common source and, in recent years, much attention has been focused in determining the prevalence of Salmonella during the different stages in the poultry production chain. This article was designed to investigate the prevalence of Salmonella serovars in retail chicken meat sold in Hanoi. A total of 262 samples were randomly collected from retail markets and examined for the presence of Salmonella. Of these samples, 48.9% were found to be contaminated with Salmonella. Predominant serotypes were S. Agona, S. Emek, S. London. The prevalence of S. Enteritidis and S. Typhimurium was considered. These findings have highlighted the magnitude of Salmonella contamination in retail chicken meat in Hanoi. On the basis of these preliminary survey results, it is recommended that a cost-effective monitoring and surveillance system for Salmonella should be established in Hanoi. This system should be augmented by good agricultural and hygienic practices and well-designed longitudinal research activities on the whole poultry production chain.
