There is no guideline to prevent H. pylori infection.
Usually the route of transmission is via kissing or unhygienic toilets.
Some people believes you can catch H. pylori from polluted water source, which I do not believe.
H. pylori survive poorly outside human body. It has always been a challenge for researchers to culture H. pylori in the laboratory. Many laboratories in the world, especially the developing ones, do not have the capability in culturing H. pylori. The reason is because H. pylori require special medium to grow and they grow extremely slow. Usually when the biopsy is taken out, and if not send to the laboratory within 1 hr, the success rate of culturing drop significantly, even if it is stored in the fridge.
In the stomach, H. pylori is the only organism that survive. There is no competition. When it's outside the stomach, because of the slow growing, it can be out compete so easily by other microbes.
In addition, there are so many articles out there that show that H. pylori can be killed by salt, vinegar, honey, chili, broccoli, sugar, etc etc. They are all true. H. pylori is even sensitive to oxygen. It has to live in a micro-aerophilic condition, where CO2 level is high. All these show that H. pylori survive poorly outside human body and one cannot simply catch H. pylori from the environment.
Nevertheless, there are far more other terrible pathogen out there that people should be aware of. especially those who likes to eat raw food, including vegetables. Listeria for example, survive in the fridge and commonly spread in raw vegetables. That's why pregnant women should avoid raw salads to avoid catching Listeria that can cause miscarriage.
