In a follow-up to a story last month, the tally in the Listeria monocytogenes outbreak linked to ‘rullepølse’ sandwich meat has increased to 38 cases, including 15 fatalities, according to an update from the Danish State Serum Institute (SSI) Monday (computer translated).


18 men and 20 women have been affected by the outbreak.

The outbreak has been traced back to sandwich meat from Jørn A Rullepølser, which has been shut down. The outbreak strain of the Listeria has been identified as ST-224 by genome sequencing, the SSI reports.

Food contaminated with Listeria monocytogenes may not look or smell spoiled but can still make you sick. Symptoms can include vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness.

Pregnant women, the elderly and people with weakened immune systems are particularly at risk. Although infected pregnant women may experience only mild, flu-like symptoms, the infection can lead topremature delivery, infection of the newborn or even stillbirth. In severe cases of illness, people may die.
