Does household oven heat kill viruses/bacteria? This afternoon I'm preparing pizza for supper

since Monday night has been Pizza Night in our house for many years. So I had a thought about
the possibility of oven heat in particular killing the virus that causes COIVID-19. The short answer is YES!

fascinating info at links:

Now before we do a victory dance let's remember that bacteria can survive traveling through the
cold vacuum of space. In fact, science tells us that our world slowly developed oceans, an atmosphere and microscopic life due to asteroid and comet strikes carrying what was needed. That has developed into what we have today. That's not really encouraging so stay tuned for Part II, They're Cold, They're Bold And They're Coming To Get Us!

1. Yes

Viruses denature at fairly modest temperatures.
For sanitization procedures in food, beverage, and consumer product manufacture, the microbiologists recommend 180F for 90 minutes.
For microbes, the destruction is a chemical reaction. There's more than one mechanism but they're either zero or first order kinetics.
So, every 10C doubles the rate.
Since pizza is cooked at 425F, that's a 345F difference, or around 190C. This increases decomposition by 2^19, or around 525,000 fold. So 90 minutes (5400 seconds), goes to just over a hundredth of a second.
And you cook it for 25 or 30 minutes.
Also, the oven is not a vacuum, so the protein part of a virus will also oxidize like crazy. Now we've got 2 different routes of decomposition.
Cooking makes it safe.

2. Yes.

One of the big advantages of cooking food is it kills most pathogens. Prions are an exception.

But a microwave won’t do the trick. Well, it can if done correctly. When this first started my sister was microwaving her cash. Viruses are too small for the microwaves. I told her if she wet her cash them microwaved it the heat from the generated steam would kill the virus.

3. I've read scary tales about the dangers of microwaving paper. I hope your Sis stays close by

when she's doing this! Guess i'll have to look up prions now... Ok, did that...

"prion [priŽon]
any of several pathogenic, transmissible forms of the core of prion protein that cause a group of degenerative diseases of the nervous system known as prion diseases. Prions have a structure different from that of normal prion protein, lack detectable nucleic acid, and do not elicit an immune response."
