AITA for telling my roommate to move out after she risked my life to prove a point

I 25f have two roommates. Jenny and Abby. Jenny started noticing her food going missing and blamed us both. I didn’t eat any of her food so I wasn’t super worried. Yesterday Jenny called a roommate meeting and when we were off work she sat down and told Abby she wanted to be paid back for the food that’s gone missing. Abby started arguing and saying it wasn’t her, it was probably me. That’s when Jenny said it couldn’t have been me because she was putting nuts into her food and in her stuff, (like food that doesn’t even make sense to have nuts in it) Because I’m SEVERELY allergic to them. She said I couldn’t have done it because I’d be dead. She said it all proud like she got Abby but I literally felt sick. I could have died. Like genuinely died. An EpiPen isn’t a cure, you still have to go to the hospital and it’s bad. Also it’s really expensive to replace them. Like for $30 of food she was willing to risk my life. She and I argued and she said she knew it wasn’t me, so that’s why she did it but I don’t believe her. I told her to move out and now both Abby and Jenny are mad at me. But it’s my life. It’s my name on the apartment. I’m fairly certain I’m justified in kicking her out but I’m double checking. It feels absolutely insane that I could lose a friendship of 4 years to something that wasn’t even my fault. Abby is pissed at me and says I’m overreacting but she also doesn’t want to move out so she’s at least somewhat on my side. Jenny is angry and not speaking to me. I told her she has 30 days to get out of my place*

Edit: Since it keeps coming up I should clarify. Nuts are allowed in the house, but not on any of the shared dishes, like pots pans, utensils or anything else. If they got takeout then that’s fine, or used their own plates and forks and such. I’m not sure exactly how many dishes she’s put nuts on and in because she is still no longer talking to me. But she said she used peanut oil to cook a pizza, so she did use some of the pans so that’s already grounds to get kicked out. My dad said I can stay with him for the rest of the 30 days and promised to completely replace all the dishes in my kitchen just in case. We’re going shopping tomorrow for new things. And I know it will disappoint some people but I’m not kicking Abby out. At least not yet. I know she’s a thief, but it’s honestly not that big of a deal to me.
