I was looking at some sites and found:
McDonalds
Chicken fat is in the BBQ and Marinara sauces
Beef "flavoring" is in the hashbrowns (I knew it was in the fries but I thought hashbrowns were ok)
Burger King:
French Toast Sticks,, Sourdough bun and Croutons contain "Natural flavors from animal and plant sources"
Onion Rings, Fries and Hash rounds say natural flavoring but no descriptions of what kind. I called the consumer relations and one of the representatives said they were all "Natural flavors from plant sources "
