If?meat is left out on the counter for too long, we all know we need to throw it out. But what about rice or pasta?
Although that carby goodness might seem harmless after sitting on the bench for a bit, you'll probably think twice about it once you hear about the bacterium Bacillus cereus.
虽然在凳子上坐了一会儿之后， carby goodness（我不知道该怎么翻译这两个词） 似乎是无害的，但如果你听说过蜡样芽孢杆菌，你可能就会重新考虑一下。
It's not a particularly rare germ. B. cereus will happily live wherever it can – soil, food, or in the gut.
"The known natural habitats of B. cereus are wide-ranging, including soil, animals, insects, dust and plants," Anukriti Mathur, a biotechnology researcher at the Australian National University, explained to Science Alert.
"The bacteria will?reproduce?by utilising the nutrients from the food products [..] including rice, dairy products, spices, dried foods and vegetables."
Some strains of this bacterium are helpful for probiotics, but others can give you a nasty bout of food poisoning if given the ability to grow and proliferate - such as when you store food in the wrong conditions.
The worst scenarios can even bring death.
In 2005, one such case was recorded in the Journal of Clinical Microbiology - five children in one family got sick from eating four-day-old pasta salad.
According to the case study, pasta salad was prepared on a Friday, taken to a picnic on Saturday. After coming back from the picnic it was stored in the fridge until Monday evening, when the kids were fed it for dinner.
That night the children began vomiting, and were taken to hospital. Tragically, the youngest child died; another suffered from liver failure but survived, and the others had less severe food poisoning and could be treated with fluids.
"B. cereus is a well-known cause of food-borne illness, but infection with this organism is not commonly reported because of its usually mild symptoms," the researchers explain.
"A fatal case due to liver failure after the consumption of pasta salad is described and demonstrates the possible severity."

A fairly common belief is that dreams reproduce the events of the day before.
