However you are free to bring non-perishable prepackaged food in limited quantities.” Source. Carnival Food/Snack Policy: “Due to concerns for food safety and contamination prevention, any food items brought on board must be pre-packaged and unopened. Homemade items or pre-cooked foods are not allowed.

Carnival Cruise Line permits guests to bring their own snacks onboard, provided they are pre-packaged, factory-sealed, and non-perishable. Items such as chips, crackers, granola bars, cookies, and candy are perfectly acceptable and can be a great way to have your favorite treats during a movie on the Lido deck or for a quick bite during shore excursions. However, homemade food, open packages, and perishable items (like fresh fruit, meat, or cheese) are strictly prohibited due to health and agricultural safety regulations. These snacks should be packed in your carry-on luggage for the embarkation process to avoid delays during security screening. While Carnival provides an abundance of complimentary food 24/7, many families bring snacks to manage specific dietary needs or simply to save money on the "specialty" sweets sold in the ship's boutiques. Note that you generally cannot take open or perishable food items off the ship at ports of call.
