"We use a blend of sunflower and canola oil to cook our chips. The kettle varieties of potato chips used to be cooked in peanut oil but we switched to sunflower oil in May of 2001. Now ALL of our potato chips are peanut-free. All of our Tortilla, Extruded Corn, and Pretzel products have always been peanut free." View: www.olddtuchfoods.ca for more information.
