Scientists warn that everyday objects can accumulate surprising amounts of bacteria if hygiene slips.

You may not realize it, but many of the objects you touch every day collect surprising amounts of bacteria, viruses, and other microbes. While most aren’t dangerous on their own, they can transfer germs to your hands—especially when shared, handled frequently, or rarely cleaned. Public-health researchers say proper and timely handwashing remains one of the most effective ways to reduce illness. These commonly touched items tend to harbor microbes because they’re handled often, exposed to public environments, or difficult to disinfect thoroughly.
