McDonalds have a VERY good allergen list online: http://www.mcdonalds.com/countries/usa/food/allergens_sensitivities/index.ht ml <http://www.mcdonalds.com/countries/usa/food/allergens_sensitivities/index.h tml> This includes all the known allergens and GLUTEN FREE or WHEAT free foods -so you can know exactly what is safe and what is not. It's a great help for us. It's a list in Adobe format - so you can print it out and keep it in the car at all times!
