Here are some additional important facts:
- Raw meats and vegetables are common carriers of bacteria and microorganisms because of their high moisture content.
- Most travelers are unaware of the organisms residing on these items.
- When these items cross our borders, they bring with them the potential to introduce exotic pests and diseases that would be damaging to our crops, livestock and the US economy.
If you wish to take something into Mexico that isn't considered contraband, make sure you declare it at the border to avoid being fined or detained.
