How long can mashed potatoes sit out at room temperature?
The answer is 2 hours. They can only stay out for two hours if they are 135 degrees Fahrenheit or above.
That’s because this recipe often has dairy products in it, so you don’t want to leave it out for a really long time.
Why mashed potatoes go bad?
Food experts say that when food sits out for more than 2 hours, it can make you sick. It is a kind of bacteria called Bacillus Cereus and can cause diarrhea and vomiting. Foods like this one are great places for this microbe to live and multiply.
Also, never mix this dish with meat to avoid them spoiling. Mixing starchy foods with meat is bad because it may make bacteria grow faster because the temperature is in the range of 40-140 degrees F, which is a dangerous environment for bacteria.
When food is warm and moist, it can create bacterias that divide every 30 minutes. That means in just 12 hours, these bacterias can multiply into 10 million new ones.
When these toxic microbes are left out on your dining table or even in your hands for a long time, they may spread to other places near them.
This can cause bad stomach cramps and diarrhea if the food has been contaminated or spoiled. It will start very soon after swallowing the food.
Why does adding dairy products make mashed potatoes go bad quicker?
Dairy products have a lot of fat and very little water. This is why bacteria can grow in them easily.
That’s why you should always put butter, milk, cheese, etc. in the fridge after opening it so it doesn’t spoil quickly. If you don’t, then there will be bacteria that convert the sugar into glucose and galactose which makes lactic acid.
Milk can turn bad if it has lactic acid in it. Milk will curdle for 24 hours. This is a sign that the milk is bad and must be thrown out.
Listeria monocytogenes is a bacteria that can be found in soft cheese. It can survive in cold temperatures and multiply continuously. This can cause terrible poisoning for elderly people and miscarriages for pregnant women.
So before you heat up your dishes, think twice. Food poisoning is terrible. It could make you sick, and the worst part is that it could happen again if you’re not careful.
So don’t reheat yours if they were left out for more than 2 hours!
