The centre’s study comes after three people died and one woman had suffered a miscarriage in the Netherlands after eating meat contaminated with listeria over a two-year period, which was reportedly linked to Dutch meat producer Offerman.
In Germany, two listeria-related deaths were also reported in the central state of Hesse.
News of the deaths led supermarkets in Belgium to issue recalls for prepackaged meat, a move they said at the time was precautionary. Offerman, a subsidiary of Belgian food group Ter Beke, has since been shut down in the Netherlands.
The Sciensano study could not identify the cause of the infections in Belgium, since isolated cases, unlike outbreaks, are not subject to follow-ups, Het Nieuwsblad reports.
