Monaghan Mushrooms Ltd. has initiated a recall of its Belle Grove brand Whole White Mushrooms because they may permit the growth of Clostridium botulinum, a deadly poison.
The company has received no reports of illness from its customers.
The Canadian Food Inspection Agency is involved, trying to determine whether other products need to be added to the recall.
The product in question is in 227-gram packages marked best before Jan. 15.
The CFIA said food contaminated with Clostridium botulinum toxin may not look or smell spoiled but can still make you sick.
Symptoms in adults can include facial paralysis or loss of facial expression, unreactive or fixed pupils, difficulty swallowing, drooping eyelids, blurred or double vision, difficulty speaking, including slurred speech, and a change in sound of voice, including hoarseness.
Symptoms in children can include difficulty swallowing, slurred speech, generalized weakness and paralysis. In all cases, botulism does not cause a fever. In severe cases of illness, people may die.
