The authors describe a large outbreak of canine salmonellosis in a municipal kennel in Tuscany. During the outbreak, 174 samples of 'diarrhetic' and 'normal' faeces and two batches of commercial dehydrated dog food were cultured for pathogenic bacteria. The results of 25, out of a total of 41 dogs (60.9%) revealed at least one faecal sample as being positive for Salmonella; incidence per sampling ranged from 12.5% to 34%. Nine of 10 samples of dehydrated food were positive. Ten totally different serotypes were isolated from dry food and faeces: the results of the pulsed-field gel electrophoresis referred to similarity between the Salmonella Montevideo, Muenster and Worthington isolates recovered from both the food and canine faecal samples.
