Carry-on liquid rule: any liquid, gel or paste must be in containers of no more than 100 ml / 3.4 oz and all such containers must fit inside a single transparent resealable bag (typically ~1 quart). Items that behave like liquids – sauces, yogurts, spreads, gels, honey – fall under this restriction. Medical nutrition and infant servings are exempt from the 100 ml limit but must be presented separately for inspection.
Powders and dry mixes: powdered substances (flour, powdered milk, protein mixes, spices) larger than about 350 ml / 12 oz may trigger additional screening or be requested to move to checked baggage on some international routes. Labelled, factory-sealed containers reduce the chance of extra checks.
Duty-free purchases: items bought after security in a tamper-evident sealed bag with an accompanying receipt are generally permitted through connecting security checkpoints, provided the seal remains intact and the receipt is visible. If you must re-screen through security, keep the sealed bag and receipt accessible and be ready to show them.
Customs and agricultural bans: many countries restrict or prohibit animal-derived products, unprocessed dairy, fresh fruit, vegetables, seeds and some plants. Examples: Australia and New Zealand have very strict bans; the United States and EU restrict certain meats and fresh produce. Always consult the destination’s customs/plant health website before travel – undeclared prohibited items are frequently confiscated and can incur fines.
Packing recommendations: keep edible items in original factory seals when possible, place small containers in a clear resealable bag for faster screening, label homemade items clearly and list major allergens, and retain purchase receipts for store-bought or duty-free goods. For baby formula, medical nutrition or prescribed enteral feeds bring documentation and present them separately at security.
Preflight checklist: verify your airline’s carry-on allowances, confirm security liquid and powder limits at departure and transit airports, check destination customs rules for animal and plant products, and stash receipts and any medical documentation in an easily accessible pocket.
Carry commercially-sealed snacks in carry-on: specific rules and quick answer
Carry commercially-sealed snacks and ready-to-eat meals in your carry-on; solid items are usually allowed, while liquids, sauces and gels must follow security limits: containers no larger than 100 ml (3.4 oz) each, all fitting inside a single transparent resealable bag up to 1 litre for screening.
Liquid and gel limits
Each container must not exceed 100 ml (3.4 oz). Place all such containers into one clear resealable bag (maximum 1 litre) and remove it for security inspection. Duty-free liquids purchased after screening are acceptable if kept in a sealed tamper-evident bag with the receipt. Infant formula, breast milk and medically necessary liquids may exceed 100 ml but must be declared and screened separately.
Customs, biosecurity and carrier rules
Agricultural and customs controls differ by destination. Australia and New Zealand ban most fresh fruit, vegetables, meats and dairy from international arrivals and enforce heavy fines for non-declaration. Within the EU, commercially sealed solid snacks from other member states are generally permitted, while arrivals from outside the EU face inspections. The United States allows many commercially processed sealed items but restricts raw agricultural products. Airlines may prohibit strong-odour or open containers (for example, durian or large jars). Check the destination country’s official customs/biosecurity site and the carrier’s carry-on policy before travel; declare all items on arrival forms when required to avoid seizure or fines.
Packing tips: keep items in original sealed retail packaging and retain receipts for specialty or large-quantity purchases; place jars and sauces upright inside additional zip-top bags to contain leaks; consume perishable items during the flight or transfer them to checked baggage if subject to destination restrictions. Failure to follow screening or customs rules can result in discard, fines or delays.
Which commercially sealed edibles are allowed through security?
Carry commercially sealed solid snacks and factory-wrapped meals; liquids, gels and spreads must follow the 100 ml / 3.4 oz limit or be purchased after screening in tamper-evident bags.
- Solids: Chips, crackers, whole fruit, bars, wrapped sandwiches and shelf-stable canned goods are generally allowed in hand baggage when unopened.
- Frozen items: Fully frozen products that remain solid during screening are treated as solids; partially thawed items with liquid runoff are treated as liquids/gels and subject to limits.
- Liquids, gels & spreads: Sauces, yogurts, soups, jams, honey and similar textures must be in containers ≤100 ml (3.4 oz) and fit inside a single transparent resealable bag (typically 1‑quart). Larger medically required or infant nutrition liquids are exceptions (declare at screening).
- Powders & dry mixes: Powdered infant formula, protein powders and spices are allowed but containers above ~350 mL (12 oz) may require separate screening; keep original packaging to speed checks.
- Vacuum-sealed and retail-wrapped meats/cheeses: Usually accepted through security, but many countries prohibit import of animal products–declare at arrival and check destination agricultural rules before travel.
- Duty‑free purchases: Alcoholic beverages and other liquids bought airside are allowed in tamper-evident bags; if you have connecting flights that require re-screening, present the sealed bag and receipts–rules vary by airport/airline.
- Baby and medical supplies: Breast milk, formula and prescription liquids are exempt from the 100 ml limit but must be declared and presented separately; bring doctor’s note or prescription for unusual items.
Practical steps: keep items in original retail packaging, place liquid-type items in the clear bag used for screening, show any medical or infant supplies separately, and verify destination customs restrictions for meat, dairy and fresh produce before travel.
How to prepare solid snacks for faster screening
Place solid snacks in clear, resealable bags and lay them flat on top of your carry-on so TSA or other security officers can visually inspect without digging through other items.
Use transparent, single-layer storage: one item type per bag, no foil or opaque wrapping. Keep factory-sealed items with labels facing up; homemade items should be sliced or opened slightly to show the interior structure.
Remove toothpicks, metal skewers, twist ties and any foil-covered portions; store sticky or crumb-prone items inside a shallow rigid container to prevent residue on screening trays.
| Container | Approx. size | When to use / Prep tip |
|---|---|---|
| Clear resealable bag (quart-size) | ~7 x 8 in (19 x 20 cm) | Multiple servings; lay flat and seal fully so agents can see contents without opening. |
| Sandwich/snack bag | ~6.5 x 5.5 in (16.5 x 14 cm) | Single serving or small portions; ideal for nuts, crackers, granola clusters. |
| Shallow rigid container (clear) | Fits screening tray, ≤3 cm height recommended | Use for soft cheeses, pastries or anything that could smear; close lid to avoid spills. |
| Original store-sealed wrapper | Varies | Leave labels visible; commercially sealed items speed visual checks. |
Keep snacks separate from liquids and electronics during screening; if an agent requests additional inspection, remove the bag or container and hold it up rather than having officers rummage. For longer trips, replace white-paper wrapping with clear bags to avoid confusion at checkpoints.
If containers need a quick clean before reuse, consult this resource for outdoor cleaning tools: best pressure washer for house exterior.
What counts as a liquid or gel: sauces, spreads and yogurts
Treat sauces, spreads and yogurts as liquids/gels when they flow, smear, require a spoon, or shed residue when tipped.
- Regulatory threshold: Most checkpoints apply a 100 ml (3.4 oz) per-container limit for items carried in carry-on. All such containers must fit inside a single transparent resealable bag (~1 quart).
- Common items classed as gels/liquids: ketchup, mustard, soy sauce, salad dressings, mayonnaise, hummus, cream cheese, soft cheeses (brie, ricotta), yogurt, sour cream, puddings, syrups, jams, honey, nut butters and spreads that smear.
- Items usually treated as solids: hard cheeses (aged cheddar, parmesan) and whole fresh fruit – if completely solid and not smearable, they typically pass without being placed in the clear bag.
- Frozen goods: Products frozen solid with visible ice across the item may be treated as solids at screening; partially thawed or slushy items are treated as liquids and must meet the 100 ml rule.
- Transfer sauces or yogurts into leak‑proof containers of 100 ml/3.4 oz or less; use screw caps and test lids for leaks before travel.
- Place every container into one clear resealable bag and present it separately at security screening.
- If an item exceeds 100 ml and is essential during the trip, buy it after the security checkpoint.
- Declare medical liquids and infant nourishment at the checkpoint; these are exempt but may require inspection.
- For spreads you plan to consume later, consider sealed single‑serve portions or commercially sealed jars under 100 ml to reduce risk of refusal.

Transporting meat, cheese and fresh produce across borders
Do not transport raw meat, soft or unpasteurized cheeses, live plants, seeds or fresh fruit and vegetables across international borders unless the destination explicitly allows them with a veterinary health certificate or a phytosanitary certificate.
Australia and New Zealand: almost all fresh produce, meat and dairy are prohibited on arrival; undeclared items are seized and destroyed or treated, and travellers may face fines or biosecurity investigations.
United States: most raw or cured meats, poultry, unpasteurized cheeses and fresh produce from foreign origins are banned; hermetically sealed tins and commercially sterilized products may be admissible but must be declared and inspected by CBP/USDA.
European Union: meat and dairy from third countries require official export health certificates, veterinary checks and entry via designated border inspection posts; plant products generally need a phytosanitary certificate issued by the exporting country.
Permits and documentation: a phytosanitary certificate covers plants and plant products; a veterinary export health certificate covers animal-origin goods. Those documents are issued by the competent authority in the country of departure and often apply only to commercial consignments rather than personal items.
Practical checklist: declare all animal and plant items on arrival forms; keep original labels and receipts; consume or dispose of perishables before crossing borders when rules are unclear; present items for inspection on request. For specific rules consult the destination authority (examples: U.S. CBP and USDA APHIS, Australian Department of Agriculture, New Zealand MPI, the national plant protection organisation of the destination).
How to check airline and country-specific restrictions for edibles
Verify the carrier’s restricted-items page and the destination’s customs database 48–72 hours before travel.
Primary official sources
Use IATA TravelCentre (iatatravelcentre.com) for quick country-by-country summaries. Check the airline’s official website for item, carry-on and checked-bag policies and any size/weight or documentation rules. Consult the destination government’s customs and agriculture agencies: U.S. – CBP and USDA APHIS; United Kingdom – DEFRA/APHA; Australia – Department of Agriculture BICON; New Zealand – MPI; Canada – CBSA/CFIA; European Union – European Commission DG SANTE pages on animal and plant products.
Search the departure and transit airports’ security pages for screening exceptions and prohibited item lists used by checkpoint staff. Look up temporary disease or pest restrictions and quarantine alerts that may bar certain products despite usual allowances.
What to prepare and who to contact
Keep receipts, ingredient lists and any required veterinary or phytosanitary certificates readily available; many countries require official paperwork for animal-derived or plant items. Contact the airline via phone or official social-media channels if their website lacks clarity; request a written confirmation when possible. For permits and certificates, contact the destination country’s consulate or the importing-agency helpdesk listed on its government site.
Check rules for each leg of your trip, including transit countries. If unsure, declare the item on the arrival card or to a customs officer upon entry to avoid fines or seizure. Store items in their original, commercially sealed containers and separate them for inspection to speed up clearance.
How to prevent spills, odors and seizure during inspection
Use vacuum-sealed pouches plus a rigid, gasketed container for liquidy or oily edibles to eliminate leaks, reduce aroma transfer and speed up inspection.
Containment strategies
Choose containers with silicone gaskets and screw-top lids (mason jars with added paraffin tape across the rim work well). Double-seal small jars with a layer of cling film under the lid and place each jar into a resealable plastic bag; squeeze out excess air before sealing. For sauces, yogurts and spreads, transfer into travel jars of 100 ml (3.4 oz) or smaller to meet standard screening limits and group those jars in a single clear quart-size bag for easy removal.
Vacuum-seal soft items or use high-barrier mylar pouches for oily snacks; vacuuming reduces aroma escape and creates a compact profile that X-ray operators can identify quickly. Place absorbent pads (like those used under raw meat) inside the outer bag to capture any eventual seepage.
Odor control and temperature
For strong-smelling provisions, use activated-carbon odor bags or carbon-lined zipper pouches; these reduce detectable scent far more than standard plastic. Freeze perishable items solid the night before travel–frozen contents are less likely to leak and often trigger faster screening. Gel ice packs are acceptable if frozen solid at security; slushy packs risk additional scrutiny and possible disposal.
Store aromatic items away from garments and electronics inside a dedicated compartment or external pocket for easy access during a checkpoint check. Include a small travel-sized deodorizer or charcoal sachet in the same compartment if lengthy transit is expected.
Label each container with clear content names and date prepared; attach purchase receipts or manufacturer labels for commercially produced snacks and treats. Original manufacturer packaging reduces subjective assessment by inspectors and lowers the likelihood of confiscation.
To minimize seizure risk, research destination agricultural rules and declare seeds, meats, dairy or produce at entry points. Keep documentation (purchase receipts, ingredient lists, export/import permits where required) easily reachable; unreadable or hidden items increase likelihood of removal.
Make inspection smooth: place all edible items in one easily opened tote or clear bag near the top of your carry-on so security staff can view contents without rummaging. If an officer requests opening, comply and offer the pre-cut vacuum bag or jar to preserve presentation and hygiene.
Bonus tip: consider traveling with a compact umbrella stored separately from edible goods; for a sturdy option see best wood market umbrella.
FAQ:
Can I pack sealed snacks and packaged food in my carry-on bag?
Yes. Most solid, factory-sealed snacks such as chips, cookies, candy and vacuum-packed items are allowed in cabin luggage. Foods that are liquid or gel-like — for example soups, sauces, yogurt, and some spreads — must meet the airport security liquid limit: containers no larger than 100 ml (3.4 oz) and all must fit in a single clear quart-sized bag per passenger. Keep packages closed and place food items in an easy-to-reach spot at the security checkpoint so officers can inspect them if needed. Also check the rules of your destination country: some places restrict fresh fruit, meat or dairy products.
Do items like peanut butter, jam or hummus count as liquids and how should I pack them?
Yes — pastes, spreads and creamy foods are treated like liquids/gels by most security agencies. If you want them in carry-on luggage, transfer them to containers of 100 ml (3.4 oz) or less and place those containers inside the single clear quart bag used for liquids. If you buy larger jars at a duty-free shop after passing security, those are usually permitted if they remain sealed in the tamper-evident bag with the receipt visible, though some airports apply extra checks. For baby food or medically necessary nutrition, declare the item at screening; these are commonly exempt from the size limit but may require separate inspection.
Will packaged food be searched or taken away at airport security or customs, and how can I avoid problems?
Both security and customs can inspect food. At security, x-ray machines and officers may open containers or ask you to remove items for closer screening; liquids and gels over the size limit are likely to be confiscated. At customs, rules differ widely by country: many destinations prohibit or restrict fresh produce, meats and some dairy products to prevent pests and disease — Australia, New Zealand and several island nations enforce strict bans. To reduce the chance of issues, keep items in original sealed packaging, separate them from other belongings for quick inspection, keep receipts for duty-free purchases, and declare any food items on customs forms when required. If you need special food for medical reasons, carry a note from your healthcare provider and the original labels. When in doubt, check the departure airport’s security guidelines and the destination country’s customs website before travel.
