| Copper | 4 hours |
It’s crucial to note that transmission primarily occurs from person to person, rather than through food. However, **the risk of contracting COVID-19 from food or food packaging is considered very low**, according to health organizations like the CDC and WHO.
Microwave Functionality: How It Works
Microwaves heat food through a process called dielectric heating. Microwaves penetrate the food and cause water molecules within it to vibrate rapidly. This rapid movement generates heat, which cooks the food from the inside out. While microwaving can effectively cook food and eliminate many pathogens, its effectiveness against viruses, including COVID-19, depends on several factors.
Temperature and Time: Key Factors in Killing Viruses
Viruses, including coronaviruses, are sensitive to heat. Studies suggest that temperatures above **56°C (132.8°F)** can inactivate the virus. When it comes to microwaving food, two crucial factors influence whether or not the virus can be killed:
- Temperature: Food must reach a temperature of at least **70°C (158°F)** to ensure proper cooking and virus inactivation.
- Time: The length of time food is exposed to this temperature is equally important. Viruses may survive shorter cooking times, even if the temperature is high.
To maximize the effectiveness of microwaving, it’s vital to ensure that food is heated evenly and reaches these critical temperatures throughout.
