Nah, it's definitely not food....And if it was it would probably only smell in one part of the fridge, but it's in the bottom and top. I don't know where this dude is, but I don't ask twice so I'll probably just take what's sealed and put it all in the deep freezer and toss the random shit that's not, then turn it off....I'll deal with this Monday if he doesn't show. My daughter is in Kansas for her Bday and my son went camping with his friend so I'll be good until they come back.
EDIT, as far as what kind....Like legit car gas....
