Why are my colonists getting food poisoning?

[Sable]

I have a kitchen with sterile tiles and an active janitor who cleans it constantly, and a cook with major passion and nearly 20 skill in cooking, but my pets and colonists are constantly getting food poisoning from an incompetent cook. Nobody else is cooking, the meals are always 100% health, and he's not under the effect of any drugs (no drugs to use in the colony). My cook used to be a trauma savant and there was no food poisoning, so would extra manipulation help?

Food poisoning from previous bad meals sticks around in the stack, to an extent. Deplete the stack of meals entirely and it should stop.
Otherwise it's probably a mod problem.

Alright, I'll try dumping all of the meals out and hopefully that works. Thanks!

There is a minimum chance of food poisoning which is achieved at around skill 10 cooking, anything above that just makes them faster at cooking. Food poisoning will always be something you run into occasionally unless you install the DLC bionics which prevent it.

When a cook makes a poisoned meal that one meal has 100% chance to poison, when placed in a stack it's averaged over the entire stack so if placed in a stack of 9 meals you then get 10 meals each with 10% chance to cause food poisoning. If that stack is never depleted the chance keeps dropping as meals are added and removed from it, but overall the average is only one colonist will be poisoned per poisoned meal the cook makes. If you make batch meals then all 4 meals will be poisoned and that will usually cause 4 colonists to get sick in a very short period of time.

Or if you accept our lord and savior Nutrient Paste Dispenser.

Food Poisoning Chance[rimworldwiki.com] from Cooking Level 9+ is max prevention, 0.1% chance of adding food poisoning.

Also putting your butchers table in the kitchen increases the chance of food poisoning.

Yes, if it pushes the room dirtiness above a threshold. If you have a 3x3 or smaller room with a stove and a butcher table, then ya the butcher table is often going to be causing that tiny room to become dirty enough to increase food poisoning chance. If you have a 10x10 room (like a freezer) with both your stove and butcher table in there, that's absolutely fine, the butcher table does basically nothing in a room that large. When a colonist gets food poisoning it will tell you if it was because of the cook or because of the room being dirty.

Butcher Table is -15 cleanliness, room cleanliness is an average of all tiles in the room so with a 3x3 room that is 9 tiles, 15/9=1.6. With a 10x10 room 15/100=0.15. A room needs to be under -2 cleanliness to start increasing food poisoning chance. The bigger issue in a small room is going to be the blood splatters if somebody is butchering while another colonist is cooking, which are again negligible in a larger room. Definitely something to be aware of, make one large room for it or multiple smaller rooms to avoid contamination.

would think that a high enough skill level would prevent food poisoning from dishes, to be honest; anybody know if there's a mod that does that?
