Consumer complaints of illnesses have spurred a recall of Unomundo brand tuna loins and steaks because of elevated levels of histamine.

Seven Seas Ltd. distributed the implicated tune in the Canadian provinces of Alberta, British Columbia, ontario and Quebec. Canadian officials report that the recalled fish may actually have been distributed nationwide.

“This recall was triggered by consumer complaints. The Canadian Food Inspection Agency (CFIA) is conducting a food safety investigation, which may lead to the recall of other products, according to the recall notice.

The notice had practically no details on the complaints of illnesses. 

“There has (sic) been reported reactions associated with the consumption of these products.”

Canadian officials are urging consumers to check their homes for the recalled tuna products listed below. The recalled tuna should be thrown away or returned to the place of purchase. 

Some of the recalled fish was sold without specific labeling.

Food contaminated with high levels of histamine may not look or smell spoiled but can still cause serious illnesses. Histamines are not destroyed by cooking. High levels of histamine in fish can cause a reaction known as scombroid poisoning. Symptoms can include burning throat, diarrhea, dizziness, facial swelling, headache, vomiting and peppery taste in mouth.

Anyone who has eaten or handled any of the recalled tuna should watch for symptoms and seek medical attention immediately if they develop.
