ECDC and EFSA issue report on Salmonella Mikawasima cases

| December 5, 2013

ecoliThe European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA) have issued a joint Rapid Outbreak Assessment in response to increased numbers of cases of Salmonella Mikawasima infection in several European countries.

Higher than usual numbers of cases have been reported in the UK, Denmark, Germany and Sweden since September, with further cases reported in France and Spain. An investigation is now underway to confirm whether the cases are linked and if there is likely to be a common source of infection.

Worst affected is the UK, where 75 cases have been reported across the country since 1 October. A total of 16 patients have required hospital treatment, but no deaths have been reported. The national public health agencies are conducting an investigation into the outbreak, but no source has yet been identified.

S. Mikawasima is an unusual serovar and was first isolated in the EU as recently as 1976 during a study of Salmonella in pigs in the Netherlands. Most reported isolations of this serovar in the EU are localised in Spain.
