I was going through customs at Baltimore International about 15 years ago. Behind me was a family of passengers off of Air Ghana. Their luggage included something under a tarp that stank like hell. Looking closer - there was a hoof sticking out. Kid you not. These folks were trying to bring an impala hindquarter into the USA.
Customs stopped them. But that was then. Under Obama, I'm sure they would get a "bon appetit" -- along with instant green cards.
