I think the thing is that you have to be ready when going through customs even though not technically on US soil. You are still going through US customs. I have been caught with 2 apples and a sandwich on 2 different occasions. Both were taken away although they really didn't know what to do with them. LOL I always bring food back with us on our flight because hubby is a diabetic and MOST times we don't have time to grab food in our connection. We always dump the food on the plane before the connection now. Not worth getting stopped and questioned.
