New Salmonella Stanley cases linked to 2011-2012 outbreak

| May 20, 2014

TurkeysAccording to a joint European Food Safety Authority (EFSA) and European Centre for Disease Prevention and Control (ECDC) report, several new cases of Salmonella Stanley infection reported in Europe since January are potentially linked to an outbreak that occurred in 2011-2012.

The two agencies have issued an update of a joint rapid outbreak assessment from 2012, which states that new cases, clusters and outbreaks of S. Stanley have been reported in four EU member states this year. Bacteria isolated from all the cases have a pulsed field gel electrophoresis (PFGE) profile indistinguishable from the strain involved in the earlier outbreak, which affected at least 710 people in 10 EU countries between August 2011 and January 2013. The conclusion is that the outbreak strain is still present in the European food supply chain.

An international report has also been published detailing the investigation into the 2011-2012 outbreak. This concludes that the primary source of the outbreak was turkey meat. The outbreak strain was isolated from turkey meat at farm, factory and retail/consumer level in several countries, suggesting that contamination occurred early in the turkey production chain.

The current EFSA/ECDC outbreak assessment recommends that action needs to be taken to detect and contain S. Stanley infections in turkey production to prevent further contamination of meat. The assessment can be found in full here.
