What should be done with a towel after drying hands?

After drying hands, it's important to consider the implications of hygiene and the potential spread of pathogens. Utilizing the towel to turn off taps can minimize contact with surfaces that may harbor germs, thereby helping to maintain cleanliness after handwashing. This method ensures that, after your hands are clean, you do not recontaminate them by touching potentially dirty surfaces, such as faucet handles.

While discarding the towel, reusing it, or placing it on a rack may seem viable, those options introduce risks. Discarding may not be practical and can waste resources, reusing can lead to the transfer of germs if the towel isn't clean, and placing it on a rack doesn't address the issue of how to turn off the taps without risking contamination. Therefore, using the towel to turn off taps is a proactive approach to safety in food handling and personal hygiene, reinforcing the idea of minimizing cross-contamination.
