Consumer Relations
Sorry no 800 number yet.

Food Allergy Network has an interesting page for products alerts. (This is
were I found the BK phone number.) The net adress is

http://www.foodallergy.org/alerts.html

 This page is great for finding phone numbers to food manufactures,but best
of all,this page is for manufactures who post alerts to changes to their
food products.

BK is listed as tryig out a new french fry in selected US markets that
contain gluten.
BK recommends  calling each individual BK in your area to obtain a
nutritional chart for the updated info on the fries. Not all BK's were
selected for the trial.

Hope this helps.
