Food poisoning is something to be careful of from the rainy season through to summer. There is an impression that it’s not a problem if you heat food thoroughly, but can you prevent food poisoning by heating it in the microwave? In this article, we will reveal the answer in the form of a quiz.
While microwaving food can be a convenient and quick way to reheat, it is not a reliable method for preventing food poisoning. By following safe food handling practices and cooking techniques, you can significantly reduce the risk of foodborne illness.
Can Heat Food in The Microwave Prevent Food Poisoning? Is It a Yes or no?
The correct answer is… “X”!
Heating food in a microwave is an effective method, but it does not guarantee prevention. The key to preventing food poisoning is to heat food thoroughly until it is piping hot in the center.
Microwave heating heats the moisture in the area where the microwaves hit, so it is inherently prone to uneven heating. In particular, with square foods, the microwaves are concentrated at the corners, making it difficult for the center to heat up, and cooking meat or fish in a block in the microwave increases the risk of food poisoning.
How to Eliminate Uneven Heating?
So, how can we eliminate uneven heating, which can lead to food poisoning?
To avoid uneven heating, it is important to heat food in small portions, turn it over halfway through heating, or mix it thoroughly while heating. Before consuming, make sure the meal is hot.
Also, if the inside of the microwave oven is dirty, the microwaves will concentrate in the dirty areas, which can cause uneven heating. Many microwave ovens have black interiors, so it is difficult to see dirt at first glance, but it is a good idea to wipe the interior with a tightly wrapped cloth after using the microwave oven.
Are there Any Bacteria That don’t Die When Heated in a Microwave?
Many food-poisoning bacteria are killed when thoroughly heated in a microwave, but two types of bacteria can withstand heat: Bacillus cereus and Clostridium perfringens.
When conditions for growth of Bacillus cereus are unfavorable, it produces special shell-like cells called spores. Once spores are produced, they are not killed by normal heating and can survive even in dry conditions. Furthermore, when food meets the conditions for growth, the bacteria emerge again from the spores and multiply.
Bacillus cereus is widely present in nature and is often found in agricultural products such as rice and wheat. Fried rice and pasta are said to be typical foods that cause this, so you can prevent it to some extent by eating them promptly after cooking.
Clostridium perfringens also produces spores like Bacillus cereus, but the direct cause of food poisoning is the toxins produced by the bacteria. Because it hates oxygen and grows at higher temperatures than normal, stewed dishes such as curry and stew, which are difficult to cool, are often the cause. Cooked foods should be eaten on the same day if possible.
An Overview
We have explained in the form of a quiz whether microwaves can prevent food poisoning. Heating food in a microwave effectively prevents food poisoning, but it is difficult to prevent it properly unless it is heated until it is piping hot all the way through. Heat food in small portions or stir during heating to prevent uneven heating and food poisoning.
Some bacteria do not die when heated, so be sure to eat the food you have prepared as quickly as possible during the hot periods from the rainy season to summer.
