A Salmonella Enteritidis outbreak in Belgium linked to eggs from a laying-hen farm has now affected 300 people, with the implicated eggs distributed to several European countries.
Belgium’s Federal Agency for the Safety of the Food Chain (FASFC) confirmed the latest case total, up from 236 cases reported in May. Those affected range in age from under one to 96, with illnesses recorded between February 2025 and July 2026.
The outbreak has been traced to eggs produced by Laerco BV. Salmonella was detected in a dust sample from one of the company’s poultry houses, with whole-genome sequencing identifying the same type of Salmonella as that found in patients. A second poultry house at the site has since also tested positive, resulting in control measures being extended across the facility.
Laerco has issued egg recalls, including products carrying stamp codes 2-BE-1073-01 to 04. The Belgian FASFC originally warned of the possible presence of Salmonella in the eggs in May.
According to a Rapid Alert System for Food and Feed notification, the eggs were distributed to France, Luxembourg, the Czech Republic, Italy, Poland, Portugal, Spain and the Netherlands. The UK was not listed among the reported destinations.
The development comes as the UK investigates a separate Salmonella Enteritidis outbreak involving 207 confirmed cases and one death. UK Health Security Agency investigations have identified eggs as the strongest food-related signal, with affected catering businesses supplied by multiple sources including egg importers. However, UKHSA has not identified a link to Belgian eggs and says there is currently no identified link to UK-produced eggs or poultry.
