⚖️ Why This Rule Exists: X-Ray Density Screening & International Agricultural Biosecurity Controls

Solid foods are permitted through security screening because they do not flow or pose liquid explosive risks. However, semi-solid spreads (peanut butter, jam, hummus) are treated as liquids under the 100 ml rule. On international flights, agricultural border authorities (CBP / CBSA) strictly regulate fresh produce and meats to prevent pest and disease vectors.

Decision Threshold: Solid food is permitted in cabin; spreads/liquids must be ≤ 100 ml. Declare all agricultural items at international customs.

Wrap solid food neatly. If traveling with dense items like chocolate blocks, cheese wheels, or protein powder > 350 ml (12 oz), place them in a separate bin to prevent secondary bag searches.

⚠️ Common Traveler Mistake to Avoid

The Mistake: Forgetting an uneaten fresh apple, orange, or deli meat sandwich in your bag on an international arrival without declaring it.

How to Avoid It: Declare all food items on your customs declaration card or consume fresh produce before crossing border control.

How to Pack Seeds for a Flight

TSA waves seeds through without blinking; agriculture officers do not. US-bound means USDA APHIS admissibility — some genera are permitted with a phytosanitary certificate, others are barred outright — and Canada-bound runs through CFIA’s own import rules. Keep seeds in the original labeled packets (unlabeled baggies read as unknown biological material), declare them on the customs form every time, and expect packets of obviously viable exotic seed to be taken. Small amounts for flowers/veg usually pass when declared; undeclared seed finds get expensive.
