Source and Transmission
The UKHSA has ruled out UK-produced eggs and poultry as the source. Evidence points to imported eggs consumed in cafes and restaurants, not at home. The agency is collaborating with European partners through the joint surveillance system to trace the origin.
Health Impact
Salmonellosis can cause severe diarrhea, fever, and abdominal cramps. Vulnerable groups, including the elderly and young children, are at higher risk. The death of one individual is under investigation, and no further details have been released.
