McDonald's has a great ingredient / allergy information on their site...but then I got to thinking that the egg battered items (like the new chicken strips, filets, etc. that have egg in the breading) may contaminate the oil that is used for the nuggets, fries, etc.
I finally let my little one try McDonald's fries with no incident because I figured the fries seemed to be cooked in a separate vat.
Does anyone have any info on how they cook -if there is a good chance of cross contamination?
