Sweden: Salmonella outbreak sickens 22, Prompts recall of fresh eggs
news desk Lord, save her
Since the beginning of December 2022, 22 disease cases with the same strain of Salmonella Enteritidis have been reported to the Public Health Authority. It is suspected that the infection originated from the eggs, which have now been recalled.
At the end of December 2022, Salmonella Enteritidis was identified in one of Sweden’s largest egg producers, which resulted in several recalls of fresh eggs.
An outbreak of Salmonella Enteritidis affecting 22 people from eleven different districts has now been identified and is under investigation. Since many of the patients had eaten dishes containing raw eggs from the collections now recalled, there are strong reasons to suspect a link to the previous discovery of salmonella in the egg product. The disease cases ranged in age from 7-90 years (mean = 40 years), twelve of the cases were women and the diseases occurred between December 7, 2022, and January 6, 2023 (see Figure 2023-01-18).
Over the past 10 days, more salmonella infections have been reported than usual. Salmonella isolates from these disease cases have not yet been classified to identify the specific strain, but since many have reported consuming products with raw eggs from batches suspected of being contaminated, there is a risk that the number of people identified as infected in the outbreak will increase.
Although due to recalls, there should be no contaminated eggs in stores or restaurants, it is possible to have eggs left at home from the recalled lots. Through the Swedish Food Agency website, you can find out who these are and what to do with these eggs.
The outbreak is being investigated in collaboration between the Swedish Agriculture Agency, the Swedish Food Agency, the SVA, the Public Health and Regional Infection Control Agency and other regional and local authorities.
