State agriculture officials are warning New Yorkers not to eat some "steamed mackerel" from a Queens distributor, for fear of contamination.

Sold throughout the metropolitan area, the fish was in uncoded, half-pound plastic bags distributed by Gusto Food Incorporated In Maspeth. The label says it's a product of Thailand.

Health officials say the steamed mackerel was sold with its internal organs still inside, which opens the door to the possibility it could be contaminated with spores that cause botulism.

Symptoms of the potentially fatal food borne illness include blurred or double vision, general weakness and difficulty swallowing.

No illnesses have been reported so far.
