One thing people should be aware is that it's illegal to cross certain state lines with citrus because of diseases that are different in FL and CA. So if you buy clementines or oranges before boarding in the US, you could be in trouble when landing, especially in California where they are very strict. I don't think other fruits are a problem.
Apples are an issue coming into Washington State. There may be other fruits or veggies for some other states.
