⚖️ 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.
