The prevalence of Salmonella spp. in pigs was evaluated in a survey of small abattoirs in Hanoi, Vietnam. Cecal contents, carcass swabs, and tank water samples were collected for bacterial isolation in various media. Prevalence rates exceeded 50% in pig samples and 62% in water samples. This increased prevalence indicates the need for risk assessment evaluations along the entire production chain.
