Ripped parts of the post:
The bacteria is best known for causing a type of food poisoning called “Fried Rice Syndrome,” since rice is sometimes cooked and left to cool at room temperature for a few hours. During that time, the bacteria can contaminate it and grow. B. cereus is especially dangerous because it produces a toxin in rice and other starchy foods that is heat resistant and may not die when the food it infects is cooked.
And
Unfortunately, that was the case for a 20-year-old student, who passed away after eating five-day-old pasta.
His story was described in the Journal of Clinical Microbiology a few years back, but has since resurfaced due to some YouTube videos and Reddit posts. According to article, every Sunday the student would make his meals for the entire week so he wouldn’t need to deal with making it on the weekdays. One Sunday, he cooked up some spaghetti, then put it in Tupperware containers so that days later, he could just add some sauce to it, reheat it and enjoy it.
However, he didn’t store the pasta in the fridge, rather he left it out on the counter. After five days of the food sitting out at room temperature, he heated some up and ate it. While he noticed an odd taste to the food, he figured it was just due to the new tomato sauce he added to it.
Yeah it’s normally just some diarrhea, maybe some vomiting, maybe some immunocompromised people will have more serious symptoms. 5 days is a long time, but so is killing a 20 year old in 10 hours.
It’s probably helpful to think of it as increasingly bad results from increasingly bad practices, and still seek to avoid the milder non-deadly results too.
