One year the US took our tomatoes but I ate one first. The regulation came in that morning. Meat was a biggie during the mad cow epidemic. Fruits were banned into BC one year probably because they grow a lot of fruit.
Read the current regulations before you start buying and preparing.
What can help if food in it's original container. Vegetables/fruit with the small labels identifying a good country of origin vs no label.
The biggies are guns, firewood, criminal background including DUI, alcohol, drugs and what have I missed?
Don't tell them you have drugs when you mean prescription medications, learned that lesson.
We've never had hassles, the doggies ignore us etc.
