While two B.C. companies are recalling specific oysters due to possible norovirus, another seafood recall is taking place in several Canadian provinces, including British Columbia.

On February 25, the Canadian Food Inspection Agency (CFIA) stated that Seven Seas Limited launched a recall for its Unomundo brand tuna loins and steaks.

The recall was prompted by reported reactions and consumer complaints as the affected product has elevated levels of histamine.

The recalled product was distributed in B.C., Alberta, Ontario, and Quebec (and possibly nationally).

The affected products include Unomundo tuna loin and steak sold in variable sizes by clerks at counters with or without a label or coding (Lot #59831 only appears on the master case).

Consumers should not consume these product and retailers, restaurants, and institutions should not sell or serve them. Anyone who is unsure if they have purchased an affected product should contact the retailer.

Histamines in fish can cause an allergic-type reaction known as scombroid poisoning.

Symptoms can include a burning throat, diarrhea, dizziness, facial swelling, headache, vomiting, and a peppery taste.

Histamines are not destroyed by cooking and histamine-contaminated food may not appear to smell spoiled but can still make a person sick.

More information about histamines and scombroid poisoning is available at the Health Canada website, which states that high levels of histamines indicates that decomposition has occurred and toxic levels can form before a fish smells or tastes bad.
