Interesting tangential note: Just in Mexico, and the customs card has a "food" box phrased basically like the US one -- fresh fruits, agricultural items, food, etc. I typically have checked "no", but thought, hey, I have food (nuts, candy) and a half case of wine (food to me), so checked yes. After inspection (which would have happened anyway due to the wine), I mentioned how I checked yes due to "food" and she said "oh, no, that's just for fresh vegetables, meat, etc." Go figure.
