Burger King claims to NOT distribute french fires containing wheat in
California.  After become ill I checked with a local manager and he told
me that they were selling wheat containing french fries.  Even he
was not aware that that had happened.
 
Moral - the head office does not always no what is shipped to every
store.  If it is anywhere in the systmes you must protect yourself in
all stores.
