Tamales still safe to eat?

[onrushpam]

My sister brought some tamales from TX (a friend of hers made them). We forgot they were in the fridge! I know they were made more than a week ago... probably on the 20th or 21st. They've been in the fridge, but not frozen. Are they still edible? They look/smell okay. I'd hate to pitch them, but am a bit fearful...
