A Listeria outbreak caused by contaminated sausages in Denmark.

Officials traced the deadly bacteria back to a meat producer in Hedehusene, near Copenhagen. 

Steen Ethelberg, from the national health agency Statens Serum Institut (SSI), said listeriosis, caused by the contamination, hit elderly people and those weakened by other illnesses.

Eight people known to be infected since the start of the outbreak have survived and the SSI is working to find any other cases. The first person died on 13 September and the latest recorded death was on 9 August, with most deaths coming in the last three months, authorities said.

The popular product is typically made of flattened pork belly stuffed with spices and herbs,which is then rolled up, sliced and served cold. Danish sliced rolled meat specialty called Rullepoelse immediately shut down after the discovery on Monday and 20 employees were sent home as sales stopped.

All products were recalled but it was not immediately clear whether any had been exported. Officials are checking whether any were sent to schools or restaurants.

The company has been investigated by food authorities before, Danish newspaper Ekstra Bladet reported.

In 1999, a batch of cooked brisket was withdrawn after listeria was found, and in 2012 it was ordered to withdraw a batch of saveloys.

Listeria causes the infection listeriosis, which can be fatal in young children, the elderly and those with weakened immune systems. The pathogen can have particularly harmful effects on pregnant women, including miscarriage and stillbirths. In most people, listeriosis is mild and causes symptoms including a high temperature, vomiting and diarrhoea that usually pass within three days without the need for treatment.
