Peanut oil has mysterious life form growing in it

I have a bottle of peanut oil that has developed some wispy white matter floating throughout the bottle.

**NOTE: This is NOT the uniform cloudiness that happens when oil is chilled. **

This is something that looks like cirrus clouds and there’s a lot of it and it is evenly distributed throughout the mostly full bottle (as opposed to being settled near the bottom). When you move the bottle, it flows around, but doesn’t clump up or anything. The bottle is a few months old, it is opened, as I’ve used a little. It didn’t have this in it when the bottle was new. It smells okay (as opposed to smelling rancid, which I can’t stand). I’ve been storing the bottle in a cupboard in the kitchen–not too hot, not too cold.

The first thing I thought was that it was some kind of fungus or mold. Or possibly an alien life form that is incubating and will soon break out (or “break bad”) and take over my neighborhood.

Anyone know what this might be? I’m probably going to throw out the bottle, 'cause this growth is giving me the creeps, but I’m still curious.

Sounds like Mr. Peanut has, uh, been there. :slight_smile:

I’d wager on some perfectly natural separation/clump-clouding that’s specific to the oil and its processing and storage conditions. All things considered, I’d toss it, though. Not worth even a small health risk from some bizarre contamination or breakdown.

Hmmm…actually it does kind of look like that. Ewww.
