⚖️ 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.

Conditions, Warnings & Legal Exceptions
👶 Traveling with an infant
Formula, breast milk, toddler drinks, and baby food are all exempt from liquid limits in "reasonable quantities" — you, not the 3-1-1 rule, decide what the trip needs.
🔍 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.
