A Salmonella Enteritidis outbreak sickened 207 people across 11 countries, with investigations by Denmark and Austria tracing the infections to meat produced in Poland.

The two countries reported the outbreaks in July 2023. Scientists have now detailed the country-level investigations that connected the cases to the Polish meat production.

The United Kingdom recorded the largest patient count at 80, followed by France with 49. The remaining cases were distributed across the other affected countries.

For European meat suppliers and importers, the case underscores how a single production source can generate multi-country food safety liability, with national authorities in Denmark and Austria doing the detective work that identified the origin.

Further published detail on the outbreak investigations may clarify what enforcement or sourcing changes follow for Polish meat producers exporting into EU markets.
