Rule #2: Reading ingredient labels is not enough.
Even if a product is labeled as gluten-free or nut-free, it may still contain traces of allergens. The only way to be completely sure is to contact the manufacturer directly and ask about their allergen control processes.
Rule #3: Allergic reactions can be delayed.
Some people may not experience symptoms of an allergic reaction until hours after consuming an allergen. This is why it’s important to always carry an epinephrine auto-injector and be aware of the signs and symptoms of an allergic reaction.
