When I've returned from cruises to the Caribbean, I've always seen amnesty garbage cans right before the customs area. They have big signs on them telling folks to toss their fruits, veggies and seeds out. The signs also warn of big fines if folks try to bring those items into the States.
Oh, yeah. Me too. However, I've also had a lot of experience with bringing grocery-store food into the country with no problem - in this instance the fruit in question had stickers, was wrapped, with price tags.
I'd have been glad to throw it away, and only mentioned it in passing because I thought it was no big deal. I certainly would have tossed anything I had bought in a farmers market, say, or from a street vendor, and would have done so in this instance had I any prior experience indicating it might be a problem.
However, the out-of-proportion, in my opinion, screening began and I was not only not offered the option of discarding the orange, but all - and I mean all - of my 2+ checked bags filled with scuba gear plus two stuffed carryons were disassembled, a LEO was brought, etc. (The suspicion level goes to 11 if you travel with scuba gear. You'd think it would be commonplace for TSA on trips to and from the Caribbean, but
every time you're treated even more like a subhuman than is usual. I've actually seen some articles in the professional literature about this lately.) It took almost an hour and I nearly missed my connection.
In the old days, I'd have said: In the future I'll simply throw away anything remotely questionable. However, given the current state of things in the airports, there won't be nearly so many future trips. I'll be enjoying my oranges in the comfort of my own home, or at a destination - like Florida - within driving distance.
