By early September, the Danish authorities confirmed an outbreak brought about by Listeria monocytogenes that has caused 15 deaths from a total of 38 affected people, according to the reports submitted by the Danish State Serum Institute (SSI).
The origin of the outbreak is to be found in the intake of a butcher’s product called ‘rullepølse’ (a roll that contains pork and spices) produced by the company Jørn A. Rullepølser A/S, and 30 products that include salamis and sausages (hot dogs), which have been withdrawn from the market.
According to the SSI, the strain that has caused the outbreak is ST-224, and it was identified by the sequencing of its genome.
The symptoms of the Listeria infection include fever, nausea, diarrhoea and vomiting. Most of the patients may start to feel the symptoms from day 7 to day 21 after the infection.
