We always remember that what we eat can become a vehicle of pathogenic bacteria for the organism and in this sense, we should know that some foods already cooked also represent a risk. Therefore, we reveal why your leftover pasta or rice should not be left out of the fridge for even an hour.
Why refrigerate leftovers quickly
Although we always think that eating raw food is more risky, we should know that more dangerous than salmonella or Escherichia coli is the picture that causes a bacterium called Bacillus Cereus that develops in cooked foods that remain at room temperature.
This bacterium can grow between 5 and 55 ° C and can reproduce until it doubles in less than 30 minutes if it is at 30 ° C. Its ingestion through contaminated food can cause two types of food poisoning: a diarrheic form that is usually a cause of contaminated meats and sausages which is the least serious form and that can be avoided with heating to more than 40 ° C, and another type of intoxication that causes nausea and vomiting and occurs in a short time after consumption of contaminated cereals ( approximately between 1 and 5 hours later).
This last picture is the case of the Belgian student who died after eating pasta that had been cooked for five days, and reheated before consumption but kept it out of the refrigerator until then.
The key to prevention is to refrigerate the leftovers as soon as possible and not store at room temperature
This emetic form of food poisoning can not be avoided with heating, because the bacterium causes spores or toxins that are thermostable and resist up to 10 minutes at 100 ° C or more, which is why even if the pasta has heated sufficiently the young student whose case today is known massively, I can not avoid the disease that was lethal.
The key then to prevent this foodborne disease is to refrigerate food leftovers as quickly as possible, especially those from cereals such as pasta or rice, which is where the spore or toxin of Bacillus Cereus most frequently develops.
