Clarus Lead

The recall affects a widely distributed sandwich product from a major Swiss retail chain and is directed at consumers who have already purchased the product. Particularly at risk are immunocompromised individuals, pregnant women, and newborns, in whom listeria can lead to severe complications up to and including death. The swift response from Denner and the BLV mitigates the risk, but consumers should check whether they still have the product at home.

Detailed Summary

Listeria are bacteria of the species Listeria monocytogenes, which occur in food and can cause infections when consumed. In individuals with intact immune systems, an infection typically runs a mild or asymptomatic course.

However, in immunocompromised individuals, severe symptoms can develop that are potentially fatal. The hazard is particularly critical during pregnancy: A listeria infection can lead to miscarriage or result in the newborn being born with sepsis or meningitis.

The BLV categorically recommends not consuming the affected product and disposing of it.
