Hey Carrie! Don't give up! I can smell things that my husband and kids do not smell. I have ALWAYS been right on this issue. Do men have less sensitive noses?

I have found that the WORST food odor is from rotten potatoes !

Check the drip pan under the fridge, and under your crisper drawers. The freezer also as someone else suggested. It could be around the fridge, behind it, in a cupboard next to it maybe.

You gotta find it or it will drive you insane! I know this because I found a rotten potato way in the back of the pantry after days of searching for the odor. I have know idea how it got there!
