Thirty people in Sweden fell ill with scombroid poisoning after eating tuna from Vietnam earlier this month.
The histamine poisoning foodborne outbreak was linked to frozen tuna loins from Vietnam, via the Netherlands.
Local authorities were responsible for the outbreak investigation and tracing of food batches. The Swedish Food Agency (Livsmedelsverket) is the national contact point for Europe’s Rapid Alert System for Food and Feed (RASFF).
Mats Lindblad, from the Swedish Food Agency, said about 30 people were sick but no deaths were reported.
“Symptoms were typical for histamine poisoning and included swelling, hives, irregular heartbeat, nausea, diarrhea and vomiting,” he told Food Safety News.
