Crunch Puffs are free of the top 9 allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, or sesame) but are made in facilities that work with them. Our facilities practice GMPs, allergen scrub-downs, and are both FDA- and CFIA-registered + compliant, but there is still a risk of allergen cross-contamination. Please be advised of this risk prior to purchasing.
