In 2011–2012, a large outbreak with more than 700 cases was investigated at the EU level. Epidemiological and microbiological information gathered through a public health, food and veterinary investigation strongly suggested that a contamination in the turkey production chain was the source of the outbreak. The distribution of cases indicates a steady spread and the transmission pattern suggests persistent common sources. The wide geographical distribution of cases and food isolates points towards a contamination of widely distributed products in several EU countries . After the implementation of control measures the number of S. Stanley cases decreased in 2013, but remained at a higher level than during the pre-epidemic period. While most of the S. Stanley cases between 2007 and 2010 were travel related, the majority of the cases from 2011 onwards had no connection to travel in the week before the onset of the disease. This indicates a change in the epidemiology of human S. Stanley infections in the EU and suggests that the strain is present and is still circulating in the European food market. In addition, the proportion of nalidixic-acid-resistant isolates increased markedly from 17% (between 2007 and 2010) to 52% (since 2011). In April 2014, an S. Stanley outbreak with a PFGE pattern indistinguishable from the 2011–2012 outbreak strain was identified in Austria. The probable source of the outbreak was turkey meat. In December 2013, Germany experienced a local outbreak of S. Stanley with the 2011–2012 outbreak strain. In addition, Hungary and Scotland report sporadic cases in 2014 caused by the 2011–2012 outbreak strain. These recent cases and findings suggest that the 2011–2012 outbreak strain is still circulating, most likely in the turkey production chain. Therefore, new sporadic cases and outbreaks of S. Stanley are expected to occur, involving other European countries.
