If you're travelling through a US airport, you might be wondering if you can bring food through security. The short answer is yes, you can take food through airport security. However, there are some guidelines and restrictions to be aware of. Solid foods, such as sandwiches, fruit, and snacks, can go through airport security. Liquids, gels, and spreadables are allowed but cannot exceed 3.4 oz. Food items in aluminium foil or containing metal may trigger the metal detector and require additional screening. It's important to note that the final decision rests with the TSA officer, and even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm or poses security concerns.

What You'll Learn
Liquids, gels, and spreadables are allowed in 3.4 oz containers
Liquids, gels, and spreadables are only allowed in containers that are 3.4 oz or 100ml in size. This is known as the 3-1-1 rule, as each liquid container must be 3.4 oz or smaller, they must all fit into a one-quart bag, and each passenger is only allowed one bag. This rule was introduced in the early 2000s after disguised liquid explosives were used in terrorist attacks.
Liquid medications are exempt from this rule and are allowed in reasonable quantities. They will need to be screened for explosives, and you may be asked to open them for a vapor analysis. Baby wipes, makeup wipes, and other wet wipes are also exempt from the 3-1-1 rule. Liquids purchased at the airport can be carried in a secure, tamper-evident bag, but they must be screened and cleared.
Food is allowed through airport security, but it must follow the guidelines and restrictions set by the TSA. Solid foods, such as sandwiches, fruit, and snacks, can go through airport security but must be screened. Liquids and gels are on the prohibited items list and cannot go through airport security. This includes drinks, soups, and sauces.

Solid foods are allowed
However, it is important to note that solid foods must go through an X-ray machine for screening. Additionally, food items in aluminum foil or containing metal may trigger the metal detector and require additional screening.
It is also worth noting that bringing your own food is especially useful if you have special dietary requirements. However, this food will still need to go through the X-ray machine for screening.
While solid foods are allowed, liquids, gels, and spreadables are subject to the 3-1-1 rule and can't exceed 3.4 ounces. This includes items such as drinks, soups, sauces, peanut butter, honey, creamy cheese, dips, and olive oil. Alcohol is also allowed in containers of 3.4 ounces or less, but 140-proof (70%) alcohol is prohibited.

Fresh food is allowed on domestic flights
The Transportation Security Administration (TSA) has a 3-1-1 rule in place for liquids and gels, which means that travellers can bring these items in their carry-on baggage as long as they are in containers no larger than 3.4 ounces (100ml). This rule does not apply to checked baggage, where the size and quantity of liquids do not matter. However, overweight bags may carry additional fees.
It is important to plan ahead and pack properly to facilitate the screening process and ease your travel experience. Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with the TSA officer at the checkpoint.
Travellers are advised to bring their own food if they have special dietary needs, but it must still go through the required screening process. It is also important to note that some countries have stricter rules regarding food items. For example, Australia is known for having strict rules about food items being brought into the country.

Baby and toddler food are allowed
Ice packs, freezer packs, frozen gel packs, and other cooling accessories are also permitted in carry-ons, regardless of whether they contain breast milk. If these items are partially frozen or slushy, they may be subject to additional screening. Strollers, car seats, and other baby-related items must also go through X-ray screening.
While baby and toddler food is generally allowed, it's important to note that the final decision rests with the TSA officer at the checkpoint. Even if an item is generally permitted, it may be subject to additional screening or prohibited if it triggers an alarm, appears tampered with, or raises security concerns. Therefore, it is always good to plan ahead and pack accordingly to facilitate a smooth screening process.

Foods in metal packaging may trigger the metal detector
When going through airport security, passengers must walk through a metal detector or full-body scanner, and their carry-on luggage is scanned through an X-ray machine. Some food items may trigger the metal detector and require additional screening. While solid foods, such as sandwiches, fruit, and snacks, can go through airport security, food items in aluminum foil or metal packaging may trigger the metal detector. Liquids and gels are on the prohibited items list and cannot go through airport security. This includes drinks, soups, and sauces, but there are exceptions, such as frozen liquids.
Foods packaged in metal may contain metal particles that can be detected by the metal detectors. These particles can infiltrate food products at various stages of production, from the raw materials to the packaging process itself. Ferrous metals (iron or iron-containing alloys) are magnetic and have good electrical conductivity, making them easy for metal detectors to recognize. Non-ferrous metals, like copper, lead, and aluminum, are non-magnetic and have good to excellent conductivity. Stainless steel is typically non-magnetic, with poor electrical conductivity, making it the hardest type of metal to detect in food products.
Food manufacturers use metal detectors to identify contaminants in food products. Metal detectors are suitable for packaged food products that aren't canned or foil-wrapped. Even small amounts of metal in the packaging can interfere with the metal detector. Frozen foods can also be inspected by metal detectors, but if they start to thaw, their conductivity may rise and interfere with the detector's signal.
Meat, poultry, and dairy products like yogurt and cheese have high moisture and salt content, which can produce signals similar to detectable metals and challenge metal detection systems. Metal detectors with a high-frequency field are better suited for these types of products. Baked goods and confectionery items may also contain metalized film or foil packaging, making it challenging for metal detectors to distinguish between product effects and actual metal contamination. However, advances in software algorithms have improved the detection process.
