Final answer:
Germs on faucets are largely neutralized by treated water, which makes it safe to use for cleaning dishes and washing. Cleanliness is relative, aiming to reduce microbial load rather than sterilizing.
Step-by-step explanation:
Concerns about germs on faucets and other surfaces are valid, as we do come in contact with various microorganisms in our daily lives. However, the water that we get from faucets is typically disinfected with chlorine or other disinfectants to kill bacteria and other harmful organisms, making it safe for washing dishes and our bodies. While it is true that antibacterial wipes and soaps are pervasive, they do not and should not eliminate all bacteria. In fact, many nonpathogenic bacteria are beneficial and necessary for a healthy body. Therefore, cleanliness is relative and geared towards reducing microbial load rather than sterilizing everything we come into contact with, except for critical items like surgical instruments.
When washing dishes by hand, dishwashing detergents with surfactants are used which greatly reduce the surface tension of the water, allowing it to rinse off quickly. It is also common to rinse dishes with pure water to remove any soap residue. This process is generally sufficient to make the dishes clean enough for eating without necessitating the removal of every single microbe. It is important to find a balance between cleanliness and maintaining a healthy microbial environment.
Hand washing with soap and water is recognized as an essential behavior in preventing the spread of diseases such as the flu and coronavirus. It is the most crucial defense against pathogens, especially those transmitted by skin contact or the fecal-oral route.
Thus, while some germs may exist on faucets, the practice of washing, whether it be dishes, hands, or the body, along with the use of household water that has been treated with disinfectants, is safe and contributes significantly to our overall hygiene and health.
