Security rules: Solid items typically pass X-ray without restriction. Gel-like items (yogurt, sauces, spreads, dips) must be in containers no larger than 3.4 oz (100 ml) and placed in a single clear quart-sized resealable bag per traveler (TSA 3-1-1). Frozen items that are completely frozen at screening are treated as solids; partially thawed items with liquid consistency fall under the 3.4 oz limit. Powdered substances exceeding 12 oz (350 ml) in hand baggage may require additional screening and could be prohibited from the cabin.
Customs and agricultural rules: If arriving from outside the U.S., declare all perishables, meats, dairy and plant material to CBP/USDA. Fresh produce, raw meat and some dairy products can be denied entry or destroyed; penalties apply for nondisclosure. For domestic transfers, check state quarantine notices – items from regions with invasive pests can be restricted.
Airline and storage tips: Verify carrier-specific policies on onboard consumption and storage. Use leakproof containers and insulated bags with frozen gel packs (must be fully frozen during screening). Place all liquids and gel-like edibles in the quart bag for rapid screening; label medical nutrition and carry receipts for prepared purchases to speed customs questions.
Quick checklist: solids OK; liquids/gels ≤3.4 oz in quart bag; frozen-solid items OK; powders >12 oz may trigger extra screening; declare agricultural items on international arrival; confirm airline rules before travel.
Allowed Snacks and Meals for Cabin Bags
Pack solid edibles (sandwiches, whole fruit, baked goods) in your cabin bag; liquids, gels and spreads over 3.4 fl oz (100 ml) must follow the 3-1-1 liquids rule or be checked.
- Liquid rule: containers ≤3.4 fl oz (100 ml) placed in a single clear quart-sized resealable bag per passenger.
- Gel/creme/paste examples treated as liquids: yogurt, hummus, mayonnaise, jam, sauces, soups, soft cheeses, and syrups.
- Frozen items: allowed if completely solid when screened; partially melted or with liquid present will be handled as a liquid and may be confiscated.
- Baby and medical allowances: formula, breast milk and prescription medications are permitted in reasonable quantities above 100 ml but must be declared at security screening.
- Security screening: expect removal of containers from bags for X-ray inspection and possible hand checks of wrappers and containers.
International travel restrictions:
- Most countries prohibit uncooked meats, certain cheeses, fresh fruit, seeds and plants without declaration; these items are frequently seized at border control and penalties may apply.
- Australia, New Zealand and the United States enforce strict agricultural controls – do not assume items allowed domestically will be permitted on arrival.
- Declare all agricultural items on arrival forms to avoid fines; if unsure, discard before departure or consume prior to landing.
Packing and preparation tips:
- Place small liquid containers inside a clear resealable bag for quick removal at security.
- Use leak-proof containers and double-bag perishables to avoid spills that trigger secondary checks.
- Label medical and special-diet items and keep prescriptions or doctor’s notes accessible.
- Freeze sauces or soups solid overnight; confirm they remain frozen when screened to avoid confiscation.
- Consider purchasing perishable meals after security or onboard to eliminate customs and screening complications.
Before departure verify three sources: your airline’s carriage policy, the departure airport security authority, and the destination country’s customs/agriculture website; follow the strictest rule among them.
Solid items allowed in cabin bags: sandwiches, fruit and baked goods
Pack sandwiches, whole fruit, and baked goods in airtight, leak-proof containers and place them near the top of your cabin bag for quick inspection; solid items generally clear security, while spreads and sauces may be restricted.
Sandwiches
Cold sandwiches with sliced deli meats, hard cheeses and raw or cooked vegetables are treated as solids and typically pass screening. Spreads sold in jars or tubs (peanut butter, hummus, jelly) are classified as gels and must follow the 3-1-1 rule: containers no larger than 3.4 oz (100 ml) and all must fit in a single quart-sized clear bag. If a sandwich contains a high-moisture filling (gravy, runny sauces), expect additional inspection; transfer those sauces to checked baggage or travel-size containers if necessary.
Fruit and baked goods
Whole fruit (apples, bananas, oranges) and commercially packaged dried fruit are accepted. Cut or peeled produce is usually allowed through security but may trigger extra screening and will be subject to agricultural controls on international arrival – declare any fresh produce on customs forms or discard before entry to avoid fines. Baked items such as bread, cookies, muffins and plain cakes are permitted. Pastries with creamy custard, loose gel-like frosting or liquid fillings may fall under the 3-1-1 limit; dense or fully set frostings and commercially sealed desserts are less likely to cause problems. For international trips, avoid fresh meats and unprocessed dairy unless allowed by the destination country’s import rules.
Label commercially packaged items, use clear containers for homemade items, and check TSA, airline and destination customs pages before departure; declare agricultural products when required and transfer any non-compliant spreads or sauces into compliant travel-size containers.
How TSA liquid rules apply to sauces, soups, yogurt, and infant purees
Put sauces, soups and yogurt into containers no larger than 3.4 oz (100 mL) and place all such containers together inside one clear quart-sized resealable bag for checkpoint screening.
Sauces, broths, dressings, yogurts and similar emulsions are classified as liquids/gels; any single container over 3.4 oz/100 mL will not pass through the security checkpoint in a cabin bag and should go into checked baggage or be handled under an exemption. Use travel jars clearly marked with volume, avoid glass if possible, and consolidate multiple small jars inside the required quart bag to speed inspection. Thick spreads (hummus, peanut butter) are also treated as gels and follow the same rule.
Frozen soups or purees that remain completely solid during screening are frequently treated like solids, but if partially thawed or slushy they will be screened as liquids. Keep chilled items frozen in an insulated cooler until you reach the checkpoint; if they begin to thaw, expect additional screening or a request to discard the item.
Infant items and medical exceptions
TSA permits infant formula, breast milk, juice for infants, and infant purees in quantities greater than 3.4 oz/100 mL. Declare these items to the officer at the checkpoint, present them separately from the quart bag, and expect X-ray screening or manual inspection; containers may be opened for testing. There is no published strict volume limit–carry a reasonable amount required for the trip–but keep quantities sensible and easy to inspect. If using ice packs or frozen gel packs to keep items cold, those are allowed but will be screened separately.
Practical tips: transfer sauces and yogurts into labeled travel jars (3.4 oz), seal lids with tape to prevent leaks, stash the clear quart bag near the top of your cabin bag for quick removal at screening, and keep infant provisions accessible and declared. Travel extras: best large umbrella that folds to small and best patio table umbrella with lights.
Packing and labeling tips to prevent spills and speed up security checks
Use rigid, leakproof containers with screw-top lids and silicone gaskets; double-seal sauces and gel-like items with a layer of plastic wrap under the lid plus a freezer-grade zip bag.
Best containers and packing technique
Choose hard-sided boxes or bento-style containers with locking clips for stacked items. Mason jars with silicone seals work well for wet items–leave about 6–8 mm (1/4 inch) headspace to allow expansion and secure the lid with a strip of tape. For sandwiches and baked goods, vacuum-seal or wrap in parchment, then place in a resealable bag to retain shape. Freeze liquids or wet items solid when feasible; frozen solids shift less and are less likely to leak. Line the bottom of the compartment with an absorbent layer (folded paper towels or a thin microfiber cloth) and pack bottles upright between firm items to prevent tipping. Use small (4–8 oz) screw-top jars rather than soft plastic tubes for creams, dips, and sauces.
Labeling and security-ready organization
Mark each container with content, preparation date, and allergen icons using waterproof labels or a permanent marker. Add short handling notes: “Perishable – refrigerate within 2 hours (1 hour if ambient ≥90°F)” and “Frozen – keep solid until screening” when applicable. Consolidate all gels, sauces and spreads into a single transparent resealable bag and place that bag in a top or removable pocket for fast extraction during screening. Attach a printed ingredients list or prescription note for specialty dietary items or supplements to avoid delays. For international departures, place a small declaration sticker for fresh produce or dairy to speed customs inspections. Final check: lids taped + double-bagged gels + absorbent liner + clear-bag of gels all ready in an easily removable compartment.
International travel rules: customs declarations, agricultural bans, and transporting meats
Declare all animal-origin items and plant products on arrival forms; undeclared goods are routinely seized and may trigger fines, quarantine, or criminal charges.
Customs declarations and required paperwork
Use the destination’s official arrival card (for the U.S. this is CBP Form 6059B) and answer agricultural questions truthfully. For any meat products intended for personal use beyond consumption at destination, carry an official veterinary health certificate and any import permit issued by the destination authority (USDA APHIS, DEFRA, Biosecurity Australia, MPI NZ, etc.). Keep purchase receipts, ingredient lists and country-of-origin labels with you for inspection.
Commercial consignments need an export health certificate, customs invoice, and often a pre-issued import permit; airlines and freight forwarders will require these documents before accepting a shipment for international transport.
Agricultural bans, examples and practical packing advice for meat items
Most countries prohibit raw, chilled or frozen meats and many cured products from regions with animal disease risk. Australia and New Zealand apply near‑absolute bans on personal imports of animal products unless a permit exists and the item meets biosecurity requirements. The EU and UK generally ban meats and dairy from non‑EU/Schengen/UK countries; travel within the single market may allow regulated movement of certain packaged products. The U.S. restricts meats from countries with foot‑and‑mouth or other epizootic diseases; commercially sealed, shelf‑stable canned meats are often admissible but remain subject to inspection.
Acceptable practices: retain original, sealed commercial packaging with full ingredient and producer information; obtain an import permit or health certificate for non‑shelf‑stable animal products; ship perishable meats using a customs‑cleared courier service with cold‑chain documentation rather than personal baggage. Frozen coolant packs must be solid at security checkpoints for air carriage; gel packs that are partially thawed may be treated as liquids by security agencies.
Transit notes: transiting through a country where baggage is rechecked can be treated as an import for biosecurity purposes–verify whether transit airports require declarations or re‑clearance. When in doubt, contact the destination’s customs/biosecurity agency and the carrier ahead of departure to confirm policy for specific meat products.
