TSA Rules for Food: What Food Can You Bring on a Plane?
Solid food is unrestricted — the confusion starts with drinks, frozen food, and anything spreadable.
Food causes more confusion at security than almost any other category, mostly because the rule isn't about the food itself — it's about texture. Solid food passes through freely. Anything spreadable, pourable, gel-like, or liquid follows the same rule as a bottle of shampoo. This guide covers the full range; for the specific liquid/gel test in detail, see What Counts as a Liquid?.
Solid snacks and packaged food
Solid food — chips, bars, baked goods, chocolate, canned soup with more solid than liquid content — has no restriction at all and can be packed freely in carry-on or checked bags.
Liquid and gel foods
Spreadable or pourable foods follow the standard 3.4 oz carry-on rule, the same as any other liquid. Peanut butter and honey are the classic examples, and they're also two of the most commonly confiscated foods because most containers people bring are full-size.
Frozen food
Frozen food is treated as a solid as long as it's frozen solid at the time of screening. If it's partially thawed and slushy, it may be treated as a liquid instead and subjected to the 3.4 oz limit. Pack it well-frozen and expect it to still be mostly solid by the time you reach the checkpoint.
Baby food
Baby food, formula, and breast milk are exempt from the standard liquids limit entirely, in reasonable quantities for the trip — see Flying With a Baby for the full picture on infant feeding liquids.
Drinks and beverages
An empty water bottle or travel mug has no restriction — the standard move is to bring it empty and fill it after security. A drink you're already carrying when you reach the checkpoint follows the 3.4 oz rule unless you bought it from a shop past security.

FAQ
- Why do peanut butter and honey get confiscated so often?
- TSA treats spreadable and pourable foods as liquids/gels, the same as any other liquid. Most travelers bring a full-size jar, which is well over the 3.4 oz carry-on limit, so it gets pulled at the checkpoint far more often than other snacks.
- Can I bring a sandwich through security?
- Yes — a sandwich is solid food with no restriction, as long as it isn't overly wet or soggy. It's a standalone container of a spread or dip that gets treated as a liquid, not a sandwich that happens to contain one.
