Possible to get away from this hand? (Turned fullhouse)

not sure why its not displaying correctly....but no raises pre-flop, and on the flop, the player on my left bet $5, and everyone called. Was this bad that I called this pre-flop bet? No one was behind and I didnt figure this flop hit anyone.

When the 5 hit, I thought I was golden. Figured someone may have hit a straight, or maybe had something like A4 for trips. Once the turn comes, is there any way to fold?
