Rule #1: The places that seem safest are often the ones that are the most dangerous.

The amount of bacteria on the toilet lid and under the seat is unknown. After one working day in their office, the BioCote company made the decision to gather samples in order to learn more about all the surfaces in one public restroom. It came out that we are continually surrounded by more than 50,000 different types of microbes. Unexpectedly, the sink was the area of the toilet that was the most filthy. It's because sinks are not as well cleaned as toilets, and that's where the majority of germs are. Later, Arizonan scientists reached the same conclusion: only 19% of all bathroom germs are discovered on the toilet, with the other bacteria being located in bathtubs and sinks. Additionally, the flush buttons, door knobs, walls, and floor are all covered in large bacterial colonies.
