Labels and Food Allergies

If you are like me, and so many people who have or seem to be developing food allergies and sensitivities to foods now a days. You understand how frustrating it is sometimes when grocery shopping and searching the food labels for any trace or sign of the allergen you are trying to avoid. In my continuous search in broadening my knowledge, I came across this here and thought it was very interesting. It definitely opened my eyes to our food labeling standards. I personally avoid anything that has "natural flavors" and "spices" as well as anything that says to have "shared equipment", "shared facility", "may contain" or "may contain traces of". What do you do to try and avoid allergens?
