Fahrenheit bo Celsius in this case → 180f is 83°C in this case it’s a pasteurization, ideally it should be 200f approx 85°C. I guess in this case it’s enough to cook the eggs, insects, nemotods and so on. But most bacteria won’t die, only the pathogen ones (for us that is). Sterility includes a much wider scope of thermophile bacteria and also viruses. Plus many bacteria will sporulate (a latent form) and don’t get destroyed hence the higher temps.
But if the ozone works, cool
