The best microwaves are constantly expanding the menu of possible food options. And because the snowball keeps growing, a popular area of concern for owners is to know how long it takes to kill bacteria in the microwave and if it is even possible. This health concern is what we’ll be examining in this article. And if you’re looking to read more on microwave cooking, check out our article here on how to cook with a convection microwave oven.
As many know, microwaves cook food by emitting electromagnetic waves that agitate the water particles within the food to create heat. However, it’s fundamental to know that, when trying to kill harmful bacteria, it’s not the electromagnetic waves themselves that kill bacteria but the heat itself.
Given that microwaves often cook unevenly, always make sure to stir or rotate your food to ensure a thorough cook.
For example, if you are trying to microwave a piece of chicken, plopping it in the microwave for even ten minutes might not be enough. It has to come to the right temperature. Given this vital fact, you can only know if your microwaved food is safe by using a food thermometer to test the internal temperature.
There’s always confusion surrounding bacterial life in conjunction with food. So, next, we’ll look at some specific examples of how to practice proper food safety when using a microwave’s heating process to kill bacteria. Also, for those inclined to the scientific method, we have an article with a step-by-step guide on how to do bacon in the microwave.
When dealing with raw food of any kind, especially raw meats or egg products, one must know the exact temperatures standards recommended by the USDA. For raw meats such as beef, pork, and lamb, the recommended minimum temperature is 140 degrees Fahrenheit. For poultry, it is 165 degrees Fahrenheit.
To ensure that all harmful bacteria have been killed, insert a thermometer into the thickest part of your food to ensure it’s cooked adequately throughout.
Like meat, eggs can also reach a safe temperature within the microwave. The recommended temperature to remove bacteria found in eggs, such as salmonella, is 160 degrees Fahrenheit.
A useful homespun trick that has become popularized (and confirmed by the USDA) is microwaving sponges to kill bacteria. By placing a sponge in the microwave for about two minutes, you kill 99.9999% of all living bacteria.
If you consider a food item to be unsafe before microwaving it, such as with spoiled food, it will remain unsafe even after reheating it.
Does boiling water in the microwave kill bacteria?
While it’s possible to boil water safely in a microwave, using a microwave-safe container is necessary as a proper safety measure. It’s also recommended that the water is periodically stirred throughout the process.
Can you microwave chicken to kill bacteria?
The USDA recommends that chicken be heated to at least 165 degrees Fahrenheit. So yes, you can microwave chicken to kill bacteria. Still, you must check that it has reached the proper temperature with a thermometer.
Can a microwave kill the coronavirus?
While evidence from the CDC claims microwaving food anywhere from 1-5 minutes can kill the coronavirus, it’s safer to use the oven, given that microwaves operate on different levels of power.
STAT: The USDA recommends that ground meat be cooked to at least 160 degrees Fahrenheit before consuming. (source)
