Shiga toxin-producing (STEC) is a zoonotic pathogen associated with illness ranging from mild diarrhoea to haemolytic uremic syndrome (HUS) or even death. Cross-sectoral data sharing provides an opportunity to gain insight in reservoirs and sources of human infections and starting points for pro-active measures. Nevertheless, phylogenetic clustering of STEC strains from animals, food and human cases is low in the Dutch surveillance system.

- The study aimed to find out which food sources contribute to human listeriosis and the specific risk factors associated with those sources, using data from the Netherlands between 2010-2020.
- It involved whole genome sequencing of Listeria monocytogenes (Lm) isolates from 756 human cases and 950 food/animal sources, along with exposure data from questionnaires.
- The results showed that cattle were the primary source of infection (62.3%), especially fresh beef, while other sources included chicken (19.4%) and seafood (16.9%), with specific foods like steak tartare and smoked salmon linked to higher infection risks.
The COVID-19 pandemic impacted the transmission of many pathogens. The aim was to determine the effect of non-pharmaceutical interventions on the incidence of diseases transmitted via food. Weekly incidence rates for nine foodborne pathogens were collected from national surveillance registries.
