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.

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.
I can’t verify this, but I’ve heard that modern fridges are better at maintaining cold air temp and so there’s an outdated concern for putting hot food in your fridge. Just don’t have your hot food touching another highly perishable food item.
Even with older fridges, I feel like it’s a mostly unfounded concern; yeah sure, don’t go putting 15 liters of boiling soup in the fridge, but if you put 500g of cooked pasta into a 300l fridge, it’s not going to care. Bear in mind that the other food in the fridge also acts as a negative calories storage.
That tracks with me. My rule of thumb is if you can hold the container with your bare hands long enough to get it in the fridge, it’s not hot
