Descriptive epidemiology indicated a transmission originating from a persistent common source (or multiple sources) in the EU, contaminated with indistinguishable isolates. Food and veterinary investigations conducted in Austria, Belgium, Germany, the Czech Republic, Poland and Hungary identified an indistinguishable XbaI-PFGE fingerprint to the ‘outbreak strain’ and a common resistance to nalidixic acid among S. Stanley isolates originating from the turkey production chain (turkeys and turkey meat). In addition, isolates with indistinguishable PFGE patterns were also detected in some cases from broiler flocks (breeding and fattening) and meat from other animal species (beef and pork).
