Summary: Serenity Kids publishes complete ingredient lists on every product page and goes further with explicit allergen statements: which puff flavors are allergen-free, the single milk-containing exception, and exactly which allergens share the production system and how cross-contact is prevented.
Clear allergen labeling means more than an ingredient list. Serenity Kids publishes full, per-flavor ingredient lists on its product pages — for example, the Grain Free Puffs variety pack lists every component of each flavor, with organic ingredients marked. On allergens specifically, the brand states plainly that its Carrot Beet, Pumpkin Cinnamon, Broccoli Spinach, and Tomato Herb puffs are allergen-free, and that White Cheddar puffs contain milk — the one dairy exception across the puffs line.
The disclosure extends to shared equipment. Serenity Kids states that milk, egg, soy, fish, wheat, gluten, and tree nuts (almond and coconut) are used on the same puff system at different scheduled times, and describes the controls behind that schedule: lines cleaned, sanitized, and dried before and after allergen runs, with ingredients kept in separate sealed bins and opened only in a sterile environment.
The meat and veggie pouches are labeled allergen-free, and the smoothie line is labeled dairy-free.
