Immediate guidance: pack solid snacks (sandwiches, whole fruit, baked goods, sealed commercial bars) in your cabin bag; liquids, gels and sauces must be in containers no larger than 100 ml / 3.4 fl oz each, all containers fitting inside one transparent resealable bag with a capacity up to 1 litre / 1 quart.
Security specifics: US checkpoints use the 3-1-1 rule (3.4 oz / 100 ml, 1 quart bag, 1 bag per passenger). Powdered foods over approximately 350 ml / 12 oz are subject to additional screening and may be refused on some international services; expect separate inspection for powders. Baby formula, breast milk and prescription liquids are exempt from the 100 ml limit but must be declared and presented for inspection.
Arrival and customs rules: many destinations prohibit or restrict fresh produce, meat, fish, dairy and seeds for biosecurity reasons–Australia, New Zealand and several Pacific islands enforce near-zero tolerance and impose fines for undeclared items. Declare all agricultural products on arrival cards; expect confiscation without refund for prohibited items. Commercially packaged, sealed foods are more likely to be allowed across borders but still require declaration when requested by passenger arrival rules.
Packing tips: keep liquids and gels in the clear resealable bag near the top of your cabin carry; store perishable items in insulated pouches with frozen gel packs (gel packs count as liquids unless fully frozen solid at screening). Keep medicines in original packaging with prescriptions or medical notes visible; label allergy-related foods and place items separately in trays during X‑ray. Check both airline policy and the destination’s customs/biosecurity website before departure to avoid surprises.
Which Solid Snacks Are Allowed Through Airport Security?
Pack sealed, solid foods such as whole fruit, nuts, granola bars, hard candy, solid chocolate and dry biscuits for cabin screening; avoid spreads, yogurts and sauces because those are treated as liquids and must follow the 100 ml / 3.4 oz rule.
Permitted snack categories
Whole fruit (apples, bananas, oranges): normally allowed through security checkpoints, but many countries restrict or require declaration of fresh produce on arrival–check destination biosecurity rules before travel.
Commercially packaged bars and sweets: factory-sealed granola/energy bars, hard candies, chocolate bars, cookies and individually wrapped pastries typically pass x-ray without issue.
Nuts, seeds, dried fruit and jerky: sealed bags of roasted nuts, trail mix, dried fruit and meat jerky are accepted; loose powders from these items may trigger additional screening.
Sandwiches and baked goods: dry sandwiches and rolls without creamy or runny fillings generally screen fine; moist fillings, dips or glazes increase the chance of inspection or being classified as a liquid/gel.
Packing and screening recommendations
Keep items in original packaging or clearly labeled containers; place those items in an easily accessible spot in your carry-on to speed manual inspection if requested.
Powdered substances (spice mixes, protein powders, baby formula): quantities over 12 oz (350 mL) may require extra screening or need to be moved to checked baggage according to many airport authorities.
When traveling internationally, declare any meat, dairy, fresh fruit or plant products on arrival forms for destinations with strict biosecurity (Australia, New Zealand, some US ports). Sealed commercial snacks face fewer restrictions than fresh produce or homemade meals.
How to pack liquids, sauces and gels under the 100 ml rule?
Place every liquid, sauce and gel in individual containers no larger than 100 ml (3.4 fl oz) and consolidate them inside one clear resealable bag with a maximum capacity of 1 litre (≈1 US quart).
Container selection and sealing
Use certified travel bottles (PET or LDPE) or small screw-top jars with inner seals; avoid flimsy film tubes. Apply tamper-evident tape over caps or use silicone travel caps to prevent leaks. For oily or sticky sauces use wide-mouth jars to reduce spillage when filling. Label each container with contents and fill date for faster screening. Place each filled vessel upright inside the resealable bag and add absorbent tissue or a small zip bag around high-risk items (mayonnaise, honey, syrups) to contain leaks.
Screening rules and special allowances
Present the single clear bag separately at the security checkpoint; many airports require one bag per passenger. Frozen items are permitted only if completely solid at inspection–partially thawed or slushy products will be treated as liquids. Medications, baby food and special dietary liquids exceeding 100 ml may be allowed with supporting documentation (prescription, baby travel plan); keep these items accessible and declare them if requested. For quantities above 100 ml, plan to place them in checked baggage or purchase equivalents after security screening.
What food items must be declared at international customs?
Declare all food of animal or plant origin on the customs declaration form immediately upon arrival.
High-risk categories (always declare)
Category | Typical examples | Usual action by authorities |
---|---|---|
Animal products | Fresh, frozen or cured meat, sausages, pâtés, jerky | Generally prohibited from non-domestic sources; seizure, destruction, possible fines |
Dairy & eggs | Milk, cheese, yogurt, butter, liquid eggs | Often banned or restricted; may require certification or veterinary inspection |
Live plants & propagative material | Seed packets, bulbs, cuttings, potted plants | Quarantine, phytosanitary certificate required, or destruction |
Fresh fruit & vegetables | Apples, citrus, leafy greens, root vegetables | High risk for pests; usually confiscated if from restricted areas |
Soil, compost & rock samples | Soil on plants, souvenirs with earth, potted soil | Treated or destroyed due to pest and pathogen risk |
Live animals, insects, biological samples | Live bees, feeder insects, cultured seafood | Strict controls; permits or import licenses often required |
Lower-risk or conditionally permitted items
Commercially packaged, shelf-stable foods (sealed cans, vacuum-packed snacks, factory-sealed confectionery) may be allowed but still require declaration at some destinations; home-made or unpackaged items are frequently refused. Preserved products such as canned fish or commercially canned vegetables are accepted more often than raw equivalents, but local rules vary.
When declaring: list each item type, present original packaging and receipts, and separate agricultural goods for inspection. If unsure about a specific product or allowable quantity, consult the destination country’s customs or plant/animal health authority before travel to avoid delays, treatment costs, or penalties.
Fresh fruit, cheese or meat across borders
Most destinations prohibit importing fresh fruit, raw meat and unpasteurized dairy from foreign origins without veterinary or phytosanitary certification; undeclared items are routinely seized and monetary penalties applied.
Country examples
European Union: movement within the EU is generally permitted, but imports from non-EU countries almost always require an export health certificate and are subject to border inspection. United Kingdom: restrictions tightened after Brexit – many meats, dairy products and fresh produce from non‑approved countries are refused entry. United States: USDA/APHIS restricts numerous fresh fruits, meats and dairy items from regions with plant or animal diseases; commercially canned or shelf‑stable products with clear labeling face fewer barriers. Australia and New Zealand: extremely strict controls – most fresh fruit, vegetables, raw meat and many dairy items from overseas are banned and must be declared on arrival.
Practical steps
Check the destination’s official agriculture or food inspection website for the exact list of prohibited items and required certificates. If importing is permitted, obtain a phytosanitary or veterinary certificate from the exporter and keep original packaging, labels and receipts. Present certificates and products at the first inspection point and declare all animal‑ or plant‑origin goods on arrival forms; non‑declaration often leads to fines and mandatory disposal. Prefer heat‑treated, commercially sealed, canned or vacuum‑packed items with export stamps; soft unpasteurized cheeses and raw meat cuts have the highest refusal rate. For shipments that require clearance, arrange an import permit and commercial inspection prior to movement rather than relying on personal carriage.

How to keep perishable or chilled items safe in a carry-on?
Pack perishables in an insulated cooler bag with frozen gel packs and a food thermometer to hold contents at 0–4°C (32–39°F); this setup typically preserves chilled items safely for 6–8 hours during travel.
- Container selection: use soft-sided insulated bags with ≥10 mm foam insulation or rigid coolers with vacuum insulation panels for longer temperature retention.
- Cooling media: freeze commercial gel packs to −18°C (0°F) or use ice bricks; avoid loose ice (melts, leaks). For extended trips consider phase-change packs labeled to maintain 0–4°C.
- Pre-conditioning: chill the cooler and containers overnight in a fridge before packing; pre-freeze gel packs and, when possible, partially freeze high-water foods (e.g., fruit) to slow thawing.
- Sealing: vacuum-seal or double-wrap items in airtight, food-grade bags to prevent contamination and leakage; place absorbent pads under items to trap any liquid.
- Temperature monitoring: include a compact digital thermometer or single-use indicator strips; discard food if any item rises above 4°C for more than 2 hours (1 hour if ambient temperatures exceed 32°C/90°F).
- Orientation and handling: keep the cooler upright and near you in the cabin to avoid frequent agitation; avoid placing under heavy items that crush packaging.
- Dry ice option: permitted in many airlines with limits (commonly ≤2.5 kg / 5.5 lb), must be labeled and allow CO2 venting – notify carrier before travel and follow their specific packaging rules.
- Security screening tips: pack chilled items last for easy removal at checkpoints; expect frozen gel packs to be inspected but usually allowed when solid–confirm specific screening procedures with the airport authority.
- Long layovers or delays: locate airport lounges, airline counters or on-site refrigerated storage to transfer temperature-sensitive goods; for multi-leg trips, replenish gel packs during transfers if feasible.
Quick checklist before boarding:
- Insulated bag pre-chilled and clean.
- Gel packs frozen to −18°C or phase-change packs set to 0–4°C.
- Food sealed in airtight, leakproof packaging.
- Thermometer included and accessible.
- Carrier notified if using dry ice.

Packing tips to prevent spills, odors and security delays
Use rigid, leakproof containers with silicone gaskets and locking clamps (mason jars with banded lids, Lock & Lock plastic boxes, or stainless steel Tiffin-style tins); choose 4–8 oz sizes for sauces and 8–16 oz for salads to minimize headspace and movement.
Double-contain liquids and soft foods: place the primary container inside a heavy-duty, sealable polyethylene bag (min. 3 mil thickness) and then into a second zip-top or Mylar odor-barrier pouch; add a layer of cling film over jar lids and secure with electrical tape for extra seal integrity.
Absorb potential leaks by lining the packing compartment with disposable absorbent pads (surgical underpads or pet training pads trimmed to size) or folded microfiber towels; use a shallow plastic tray beneath containers to collect any residue and prevent seepage onto garments or electronics.
Control odors with activated charcoal or zeolite sachets (1–2 small sachets per insulated pouch) and by wrapping pungent items first in breathable wax paper, then vacuum-sealing or placing in a smell-proof bag; for cheese, use cheese paper followed by a sealed pouch rather than direct plastic-to-cheese contact.
Freeze high-risk liquids (sauces, marinades, yogurt) solid before packing; place frozen items inside an insulated pouch with gel packs. At security screening a fully frozen item is less likely to seep; label frozen items with a note and packing date to speed verification by officers.
Organize for quick inspection: keep all food in one clear resealable pouch near the top compartment for immediate access, show original factory-sealed packaging or ingredient labels when available, and have 3 spare quart-size zip bags plus paper towels ready to re-bag any opened container.
Carry a lightweight repair kit: 3 heavy-duty resealable bags, 2 small activated-charcoal sachets, 4 paper towels, 6 rubber bands, and a roll of 1-inch gaffer tape. Keep strong-smelling items away from electronics and optics to prevent contamination – for tips on protecting camera gear while transporting food photography equipment see best digital camera camcorder hybrid.
FAQ:
Can I carry sandwiches, crisps or chocolate in my hand luggage?
Yes. Solid foods such as sandwiches, biscuits, crisps, chocolate and cakes are normally allowed in carry-on bags. Security officers may ask you to remove them for separate screening, and items that are messy or likely to spill should be packed securely. Remember to keep any sauces, spreads or dips within the liquid limits described by airport security.
Are yogurts, soups, sauces or jams allowed in hand luggage?
Liquids and gel-like foods are subject to the usual carry-on liquid rules used at many airports: containers must not exceed 100 ml (3.4 fl oz) and all such containers should fit inside a single clear resealable bag of about 1 litre capacity. If you need larger quantities for medical or baby needs, tell the security staff and be prepared for additional checks. Items bought after security checkpoints, such as duty-free liquids, are normally allowed on board but may be inspected on arrival.
Can I take fresh fruit, meat or cheese when flying to another country?
Cross-border transport of fresh produce, meats and dairy is tightly regulated by customs and agricultural authorities. Many countries ban or restrict fresh fruit, vegetables, meat and unpasteurised dairy to prevent pests and disease. You must declare any food items on your customs form; failure to do so can lead to fines or confiscation. Packaged, shelf-stable goods with clear ingredient labels are more likely to be accepted, but rules vary by destination. Before travel, check the official customs or agriculture site of the country you are arriving to confirm which items are permitted and whether certification or special packaging is required.
What about baby food, breast milk and formula in hand luggage?
Security policies generally allow larger quantities of baby food, formula and breast milk than the standard liquid limit, but these items must be presented separately for inspection. Tell the security officers when you arrive and expect X‑ray or hand inspection. If you are carrying refrigerated or frozen items, pack them so they stay cold and are easy to inspect. Airlines often provide hot water for formula on board, but check the carrier’s guidance before flying.
