⚖️ 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.

🔍 Security Checkpoint & X-Ray Screening Advice

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.

How to Pack Yogurt for a Flight

Airport-breakfast math: most single-serve yogurts are 5.3 oz, roughly 50% over the limit — eat it in the security line, not at the scanner. School-snack cups (4 oz) are still over; only kid-size 3 oz cups or a decanted travel pot actually make it through.
