I read the current kibble page, where it stated that cooking kibble is a great way to train unskilled pawns, as there is no chance for food poisoning. I think this sentence should specify that this is only the case when kibble is fed to animals. When fed to humans, it CAN lead to food poisoning. This happened in my vanilla game, without dlc or mods, this evening. I fed a human prisoner kibble, and she contracted food poisoning.
Please do not ask why I want to feed human pawns Kibble. It is self explanatory (especially if one is operating under the assumption that it completely prevents all risk of food poisoning).
