What Should I Look for on Food Labels if My Child Has Food Allergies?

How to Read Food Labels to Spot Allergens

If your child has a food allergy, always avoid any food whose label says it contains your child's allergen.

Keep these tips in mind:

  • Check ingredient lists and look for advisory statements such as "Contains peanuts." Some companies also voluntarily share cross-contamination warnings, such as "May contain soy," "Processed in a facility that also processes shellfish," or "Manufactured on equipment also used for tree nuts." But manufacturers do not have to list cross-contamination warnings. Products without advisory statements also might be cross-contaminated and the company chose not to label for it. So, it's always best to contact the company to see if the product could contain ingredients that your child is allergic to.
  • In the United States, companies must state, in understandable language, if a product contains one of these common food allergens: peanuts or tree nuts, eggs, milk, wheat, soy, sesame, fish, or crustacean shellfish.
  • Know the limits of food labels. Not all allergens will be included in ingredient lists or named in a recognizable way. This is often the case with allergens other than the most common ones. Sometimes, an allergen could be hidden in a long list of scientific-sounding ingredients or included in "natural flavors," "coloring," "spices," or other additives.
  • Double-check every package of food you give your child: first, in the store where you buy it and again before you give it to your child. This is important even if your child has had the product many times before. Ingredients and cross-contamination risks may change over time. Different size products may have different ingredients or be made in different facilities.
  • Remember to also check non-food items because they're not subject to the same labeling regulations. Allergens may be found in cosmetics, bath supplies, cleaning supplies, sunscreens, art supplies, kitchen sponges, and gardening supplies. Look up any ingredient that you're not sure about, and call the company with any questions.
