Identification of Salmonella spp. carrier sows is an important factor for the implementation of control programs at farm level. In this study we observed the transmission of Salmonella on the farm during the technological flow, by faecal sampling from gilts, their piglets until weaning age, the piglets after weaning age, and from youth at fattening, prior slaughtering. Identification and isolation of Salmonella was done by two methods: SR EN ISO 6579:2002, or by molecular methods (PCR). The prevalence of Salmonella spp. after examination of (n=150) samples of faeces was 50% at sows and their piglets , observing a slight increase in piglets after weaning (78.57%) and the fattening pigs (90%). The most common serovars isolated were S. Typhimurium, S. Derby and S. Newport. Study results indicate that sows are a source of contamination of piglets, and the presence of salmonella during other stages may be due to environmental stress factors and the Salmonella carrier state.
