From foodallergy.org...
"The FDA exempts highly refined peanut oil from being labeled as an allergen. Studies show that most individuals with peanut allergy can safely eat peanut oil (but not cold-pressed, expelled or extruded peanut oil – sometimes represented as gourmet oils). If you are allergic to peanuts, ask your doctor whether or not you should avoid peanut oil."
Not worth taking the chance in my book.
