In a follow-up on the Salmonella Newport outbreak in Sweden, Folkhalsomyndigheten reports the Salmonella Newport outbreak that began late July has grown to 31 cases. The cases are spread in 12 counties and from July 31 to October 30.


Health and Food Agency officials continue to investigate. The Public Health Authority has conducted a case-case study with the aim of identifying a potential source of infection and found  that it was 28 times more common that the outbreak cases had eaten crayfish compared to the control group. Most cases have eaten Chinese crayfish from ICA and a few other brands have also been mentioned.

To date, analysis of crayfish purchased in stores have been negative. Despite this, the frozen crayfish is considered to be the likely source of the outbreak and the product has therefore been recalled.

ICA issued the recall today of the ICA Large crayfish, Chinese pre-cooked frozen.

The recall relates to ICA Large crayfish, Chinese pre-cooked frozen, 700 grams, all best-before date. The product may have been sold in stores throughout the country.

If you have eaten the crayfish earlier this year and feel good, you need not worry at all, but if you still have these crayfish in the freezer you should return them to the store or advertise through our website, says Niklas Warén, Quality Manager ICA Sweden.
