Three people have died from listeria-infested asparagus soup at Odense University Hospital.
“There are two different outbreaks and they are not connected. In the asparagus soup, it is a completely different strain of listeria than in the rullepølse outbreak. The deaths we have listed on our website are only from the rullepølse outbreak,” Tyra Grove Krause of the Danish State Serum Institute (SSI) told Ritzau news agency.
The asparagus soup outbreak has sickened five patients over the past six months. Three of the infections proved fatal, with the most recent death in April.
A recent check by the Danish Food and Veterinary Service (Fødevarestyrelsen) found traces of listeria in three soups at Odense University Hospital and Svendborg Hospital. Listeria was also found in meatballs served with the soups.
The infected asparagus soup was served to patients through September 21st.
SSI reported on Wednesday that the rullepølse outbreak, which was traced to the food company Jørn A Rullepølser, is believed to have abated. SSI has not found any symptoms of infection for over 14 days.
In all, 38 people were infected through the rullepølse outbreak, with 16 dying within 30 days of being infected. The last recorded death was on August 25th.
