Meanwhile, 20 people fell sick recently in Sweden due to histamine levels in fish. The foodborne outbreak was linked to tuna from Vietnam.
In April 2021, 19 people were affected by histamine poisoning in Stockholm after eating tuna loins from Vietnam at three different restaurants.
In 2020, there were three outbreaks of histamine poisoning in tuna from Vietnam in three months. These incidents affected about 60 people but contaminated tuna came from different batches. Patients were from different areas in southern and central Sweden.
