A person infected with the Salmonella enteritidis bacterium usually suffers from fever, abdominal cramps, and diarrhea beginning 12 to 72 hours after consuming a contaminated food or beverage. The illness usually lasts four to seven days.
There were reported cases in Belgium, Denmark, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom. Croatia also reported a cluster of cases possibly associated with the outbreak, including one death.
A linked between the outbreak and an egg packing center in Poland has been established through whole genome sequencing, food and environmental investigations and trace-back investigations. Evidence suggests eggs as the most likely source of infection.
Polish competent authorities and Member States to which suspect eggs were distributed have now halted distribution.
European Centre for Disease Prevention and Control (ECDC) and European Food Safety Authority (EFSA) recommend that EU Member States step up their monitoring to contain the outbreak and promptly identify possible new cases.
