  • Outbreak of Salmonella Typhimurium linked to Swedish pre-washed rocket salad, Sweden, September to November 2022

    • In September 2022, the Public Health Agency of Sweden observed an increase in domestic Salmonella Typhimurium cases through the Swedish electronic notification system, and an outbreak strain was identified with whole genome sequencing. Overall, 109 cases with symptom onset between 17 September and 24 November 2022 were reported from 20 of 21 Swedish regions. The median age of cases was 52 years (range 4-87 years) and 62% were female. A case-control study found cases to be associated with consumption of rocket salad (adjusted odds ratio (aOR) = 4.9; 95% confidence interval (CI): 2.4-10, p value < 0.001) and bagged mixed salad (aOR = 4.0; 95% CI: 1.9-8.1, p value < 0.001). Trace-back, supported by Finnish authorities who identified the Swedish outbreak strain in a Finnish cluster during the same time period, identified rocket salad, cultivated, pre-washed and pre-packed in Sweden as the likely source of the outbreak. No microbiological analyses of rocket salad were performed. Our investigation indicates that bagged leafy greens such as rocket salad, regardless of pre-washing procedures in the production chain, may contain Salmonella and cause outbreaks, posing a health risk to consumers. We emphasise the need for primary producers of leafy greens to identify possible contamination points to prevent outbreaks.

  • Alcohol-based hand-disinfection reduced children's absence from Swedish day care centers
  • 2008
  • Ingår i: Acta Paediatrica. - Oslo : Taylor & Francis. - 0803-5253 .- 1651-2227. ; 97:12, s. 1672-1680
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To determine if the use of alcohol-based hand-disinfection as a complement to regular hand washing at daycare centers (DCCs) can reduce the childhood rate of absenteeism. Methods: Children aged 0–6 years attending DCC were studied in a cluster randomized controlled trial during 30 weeks. Thirty matched pairs of DCCs were included in the study, where one of the DCCs was randomized to intervention and the other to control within each pair. The intervention consisted in children and staff using alcohol-based oily disinfectant gel containing 70% ethanol after regular hand washing. The main outcome was the rate of episodes of absence from DCC due to infection. A regression model was fitted at the individual level and controlling several possible confounders for illness. Absences were reported by the parents. Results: Differences in missing absence reports between the two groups led to only evaluating those 29 DCCs (1431 children) that were able to provide complete reports. In the multivariate regression, the intervention significantly reduced the rate of absenteeism of a child by 12% compared to a child in a control DCC (IRR 95% CI: 0.799–0.965).
