Butchering animals for meat/food? And rotting.

[Galileus]

And that's exactly why this ain't such a great idea.

You can set up a farm and people will work it. With metal not only you must mine everything manually, it's also a finite resource. It's also counter-intuitive. It also forces you to spend your building materials actively, which is simply not a great way to set up your base builder. It's not starcraft, there's a lot of people who simply like to sit on a hoard of metal, and not worry afterwards when they need to build something.

Actually, I have no idea either why I though about rotting food instead of bodies nor why I thought for sure it has to be in a timescale where this day or two of food lying on ground would be enough to start it...

With good timescale rotting food would actually be a nice addition. It would be a natural limiter, could be used to introduce a (partial) soft cap to population (with diminishing returns from harvesting more food) and add some nice diversity to food types.

I agree 100%

I agree. As of implementation, I think it should just turn in filth or debris, without any dangerous mezostate (user will never be able to control that anyway).

More complicated implementation would require the doctor to check foods and heal the people that got sick from rotten food. That would be more fun maybe, but it's just a dream.

I got an idea.. maybe when food rots it creates a sort of "rotten fog"
It would give colonists a bad thought and encourage you to clean it up? (Until it disappears on its own)
Maybe?

Any filth gives them bad thoughts. And I even believe that different types give differently bad thoughts.
