#139 - Understanding Food Allergy Labels & "May Contain" in the U.S.

Reading food labels can feel like a full-time job when you or your child has food allergies. Even when you know what to avoid, labels can still be confusing, especially when you run into “may contain” warnings.

Marion Groetch, a registered dietitian with decades of experience in food allergy care and education, joins us to unpack all things food labels. Together, we break down U.S. allergen labeling laws, what parts of the package actually matter, and why “may contain” statements are a much grayer area than most people realize. We also share practical tips for navigating so-called “mystery ingredients” like natural flavors and oils, when it is worth contacting a manufacturer, and how to avoid being more restrictive than necessary while still staying safe.

What we cover in our episode about food labels:

• What U.S. labeling laws require: How FALCPA and the FASTER Act protect families by requiring clear disclosure of the Top 9 major allergens.
• Where allergy information actually lives on a label: Why the ingredients list and “Contains” statement matter most, and why front-of-package claims should be ignored.
• What “may contain” actually means: Why these statements are voluntary and unregulated, and what that means for real-world decision-making.
• Foods that fall outside labeling laws: Common situations where allergen labeling is not required, including deli foods, restaurant meals, airline meals, and alcohol.
• How to avoid over-restricting your diet: Practical guidance on mystery ingredients, higher-risk products, and when contacting a manufacturer actually makes sense.
