Since 2000, the National Reference Center for Salmonella (CNR-Salm) has been studying antibiotic susceptibility using a representative sample of strains. Surveillance of non-human-origin Salmonella is conducted through the Salmonella network, which comprises approximately 150 veterinary and food-industry laboratories throughout France. They regularly and voluntarily submit to AFSSA the strains they have isolated during investigations, self-monitoring, surveillance programs, or regulatory inspections for serotyping, along with their own serotyping results. This article presents the data collected by the CNR in 2002 regarding the 10 most common serotypes. The evolution of resistance between 2000 and 2002 among the main Salmonella serotypes is highlighted. (R.A.)
