Dear Mr. Jennings:
Thank you for contacting Chick-fil-A.
We have exclusively used refined (heat processed) peanut oil to cook our chicken since our founder created the Chick-fil-A sandwich in the 1960s. He found it to be the purest oil to use, which was both healthy and better tasting to our customers. Because there was understandable concern, we began in 1999, labeling our foil bags and nugget boxes informing customers of our use of peanut oil. We also communicate our peanut oil message through our Web site, nutrition brochures, and our menu boards. The menu boards include a message about the use of peanut oil at the bottom of some of the panels. However, peanut oil is not listed as an allergen on the Allergen information on our website, as highly refined oils are specifically exempt under the HYPERLINK "http://www.fda.gov/Food/GuidanceRegulation/GuidanceDocumentsRegulatoryInformation/Allergens/ucm106187.htm"Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA), as research shows they do not cause allergic reactions!
in most individuals allergic to the plant in its original form.
Most commercial oils such as peanut oil are highly refined (hot solvent extracted), which removes protein from the product. These types of oil are most commonly used in commercial food preparation. Since it is protein in allergenic foods that causes food allergy, highly refined oils are non allergenic, research has shown that individuals with a severe peanut allergy have not had reactions to heat processed oils. However, people with a food allergy should avoid "gourmet" or cold pressed oils because they may contain allergenic proteins, which provide the flavor to the oil. For the same reason, oils that have been used to fry potentially allergenic foods should be avoided by allergic individuals.
Again, thank you for your time and interest in Chick-fil-A.

Just The Chicken Sandwich.
