I'll just copy and this from my post elsewhere....
My niece had her hummus confiscated the other day. However, I believe that had more to do with, as the TSA screener put it, "Trader Joe's is my favorite hummus!" than it had to do with the safety of our nation's skies. No word on what is the screener's favorite cracker is, as they were not confiscated.
I also donated a 4 ounce bottle of sunscreen at the checkpoint in FLL. Even screeners should protect from those Florida UV rays.
