I've carried (small food items, cookies, a banana) food/snacks off international flights many times and have never been questioned or challenged about it. For a fact, they see/ sniff out stuff like this every day at every international airport and they confiscate and destroy it. Meantime people come into this country every day (legal and illegal) with TB, other diseases and all their social ills that American taxpayers get stuck with and carry the brunt of expenses for. Just another over-zealous, power-tripping CBP agent in a bad mood ?
