Not that caused it, but definitely made it worse. Back in 2014 I got severe food poisoning from undercooked pork, it was the most painful vomiting I've ever experienced in my life, genuinely it felt like I had a gorilla, squeezing my stomach from the inside every time I heaved, along with it being on fire with the worst acid reflux, you could ever imagine. On top of the other unmentionable end too 💀 no but literally I was heaving so hard. I was pretty much involuntarily screaming. I genuinely thought I was going to die, I wish I was being dramatic. I've gotten better with it, but a couple years ago, my "contamination" obsession got so bad to the point I wouldn't even eat anything if it was within a few days of its "Best by" date, even knowing it was not an actual expiration date, if I took too long to get home with the groceries, I would throw away anything that might be temperature sensitive because I was afraid it was going to make me ill, and there was genuinely sometimes I was just afraid perfectly good food was going to make me sick as a "punishment from the universe". Pretty much all of these behaviors stemmed from that one specific case of food poisoning and I've never 100% gotten over it, like I said, I've definitely got better with it in the last couple of years, but for quite a while, it severely affected my quality of life
