Can Cooking Kill Covid-19?
Cooking can indeed play a role in reducing the risk of Covid-19 transmission through food. The virus is sensitive to heat, and cooking food to the recommended internal temperature can help inactivate the virus. However, it’s essential to note that cooking alone may not be enough to completely eliminate the risk of transmission.
It’s also important to follow proper food handling and preparation practices to minimize the risk of contamination. This includes washing hands thoroughly, cleaning and sanitizing surfaces, and separating raw and cooked foods. By combining proper cooking techniques with good hygiene practices, individuals can reduce their risk of contracting Covid-19 through food.
What Temperature is Required to Kill Covid-19?
The World Health Organization (WHO) recommends cooking food to an internal temperature of at least 149°F (65°C) to inactivate the Covid-19 virus. This temperature is hot enough to break down the proteins and disrupt the structure of the virus, making it unable to infect cells. It’s essential to use a food thermometer to ensure that the food has reached a safe internal temperature.
It’s also worth noting that the temperature required to kill Covid-19 is not unique to this virus. Many other pathogens, including bacteria and viruses, are also inactivated at temperatures above 149°F (65°C). Therefore, following proper cooking techniques can help reduce the risk of foodborne illness in general.
Does Cooking Method Matter in Killing Covid-19?
The cooking method can play a role in killing Covid-19, but it’s not the only factor. What’s more important is the internal temperature of the food.
