The Canadian Food Inspection Agency says Orange Blossom Farm is recalling its unbranded relish because it may permit the growth of Clostridium botulinum.
The product was sold in 500-millilitre bottles at the St. Jacob's Farmer's Market, near Waterloo, Ont.
The agency says food contaminated with the toxin may not look or smell spoiled but can still make you sick.
Symptoms can include nausea, vomiting, fatigue, dizziness, blurred or double vision, dry mouth, respiratory failure and paralysis.
The CFIA says there have been no reported illnesses due to the relish.
