Do blueberries need to be refrigerated?

[jfulcer]

We left some blueberries we bought at Sams in the car overnight and only noticed them in the afternnoon the next day. They had been in the van and it was pretty hot out.

Is it still ok to eat them? I've been afraid to try, but they are soooo good. They are refrigerated now, of course. :)

Soooo, can I eat them?

Chances are they are cooked. Do they seem pretty firm? If not, I'd make a blueberry pie, cobbler, sauce or pancakes.
