Twenty-four cases of hepatitis A were identified in the Netherlands between November 2024 and February 2025, all linked to the consumption of frozen blueberries from a specific supermarket chain. The patients, aged between 16 and 77 years, presented with symptoms of acute liver disease. Epidemiological investigation and detection of hepatitis A virus RNA in blueberry samples confirmed the source of infection. Eight patients required hospitalization, but no deaths were reported. Product recall and hygiene measures are crucial to prevent further spread.
