H. pylori dishes can generally be given autoclaving, which usually takes 10-15 minutes or boiling water, which usually takes half an hour, or using sterilizer ozone sterilization, which usually also takes more than half an hour. For H. pylori, if it is applied to patients with a DPM greater than 700, active sterilization needs to be given, if the DPM is less than 200, for H. pylori patients with tableware, no special sterilization needs to be given. Because every patient has more or less H. pylori, as long as the pathogenic amount is not reached and as long as there is no obvious ulceration, clinical observation can continue without special treatment. Current guidelines state that H. pylori is not a direct pathogenic factor in the human body, but a bacterium that co-parasitizes with the body at the same time.
