I was interrogated and detained last August at ATL - selected for secondary, interviewed at length, made to unpack and re-x-ray luggage - for telling a staffer when asked that I had a single orange in my handbag, which I had purchased at a grocery store in the Caribbean.
Also, had a jar of Kentish Bramble - an awesome jam you can buy at London's Borough Market - taken away from me when I packed it in my carry-on. (Someone let me know if there's an outlet I can buy this online. Sigh.)
You may want to ship that food via UPS or Fedex.. If they haven't been taken over by foolishness in this regard, I mean (I haven't shipped food internationally lately.)
