Pork safety in alternative pig-production systems, status on Salmonella
This study is part of a large research project (PIGAL) jointly studying animal health, biosecurity, animal welfare and veterinary public health in alternative pig farms. It aims to assess Salmonella shedding by growing and finishing pigs. The study has been conducted in 100 alternative pig farms (size > 100 pigs), in continental France. In each farm feces of 10 growers and 10 finishers have been sampled. Detection of Salmonella has been conducted on feces with a four-step protocol adapted from the NF-U47-102 standard. Strains have been serotyped (ISO/TR 6579-3) and sequenced.
