Our pouches have a tamper evident seal that clicks during opening, keeping the product fresh. Our pouch food is cooked, and utilize a specific blend of ingredients and balanced acidity levels to ensure product safety. However, in rare instances a pouch may become compromised. Be sure to always check that the pouch is not leaking or bloated before giving it to a child, as it signifies a quality issue. If you notice that the pouch packaging has been compromised in any way, such as a bloating, or a tear or puncture, we do not advise or recommend that you feed the product to your little one.
