Great question. There are two likely explanations:
- The food is packaged in a facility that also processes gluten / soy / nuts. If you or someone you’re shopping for have a food allergy, it’s best to avoid the product entirely. The product should disclose this on the package.
- The ingredients have been updated or the packaging facility changed to protect those with allergies, and our data missed it. If the allergen you are trying to avoid does not show up in the ingredient list OR in a warning on the package about the production facility, it should be OK for you to eat.
