The Canadian Food Inspection Agency is warning consumers not to eat a brand of frozen fish called School of Fish frozen leatherjacket because it may be contaminated with ciguatera toxin.

Fish contaminated with ciguatera toxin may not look or smell spoiled, but the marine biotoxin accumulates in fish and causes an illness in humans called ciguatera poisoning. The toxin is not destroyed by cooking.

Symptoms include gastroenteritis (vomiting, cramps, diarrhea), itching of the skin and central nervous system dysfunction, which often includes hot and cold inversion, meaning, for example, that cold foods or drinks feel hot and a hot shower feels cold.

The CFIA reports two illnesses associated with the consumption of the fish.

The warning covers School of Fish brand frozen leatherjacket sold in packages of various weights bearing production code HI04 and one of the following size and UPC combinations:

· Size 100/200 and UPC 8 74718 00074 0; or,
· Size 200/400 and UPC 8 74718 00073 3.

The fish were sold in British Columbia and Ontario.
