Host: Should I fry allergen and non allergen foods in the same cooking oil?

Bob Gravani: Well when it comes to cooking oil, if a product is -- an allergen is cooked in the cooking oil and then a non allergen product is followed in it, there could be some carry over and there is a very specific example that occurred in the food service industry where a consumer came into a restaurant and ordered French Fries and went into an Anaphylactic shock and actually died. What happened was, the fish was fried in frying oil and then the French fries were fried in that same frying oil and there was carry over and because of this person severely allergic condition, it triggered Anaphylactic shock and caused a death. So clearly the bottom line is make sure that you have separate cooking oils for allergen type products and non allergen products and if it's in a household I would avoid even having that offending allergen present.
