Helicobacter pylori usually lives for about 1 hour on tableware. Helicobacter pylori is a kind of bacteria living in the human body, and it will adhere to the mucous membrane layer and reproduce after entering the stomach. The survival of Helicobacter pylori needs to meet the following three requirements: the right amount of oxygen, the right temperature, and the right acidity and alkalinity. The stomach is able to fulfill these three conditions, which makes it a breeding ground for H. pylori. After H. pylori leaves the gastric mucosa, it usually can only survive for about 1 hour because of the lack of appropriate temperature, oxygen and pH support. Dishes do not provide a parasitic environment for H. pylori, therefore, through research H. pylori can usually live for about 1 hour on dishes. If the patient has H. pylori infection, pay attention to meal hygiene, avoid contact with family members, and seek medical attention and treatment as prescribed.
