The other information you posted is correct, but some of this information is not. I bolded what is not. I am certified in Infection Control, currently working as an infection Control Nurse. I also worked in Public Health for 14 years and did a lot of investigations of possible foodborne ourbreaks during that time.
Hot water is not necessary for washing hands and is actually harmful because it strips the natural oils from the hands and can cause skin problems (drying, cracking). Water hot enough to actually make a difference to the germs on hands would cause skin burns. Soap is formulated to work best in warm water, so that is best (and safest to the hands) to use. If you don't have warm water, cold is OK too. The scrubbing action actually loosens germs and the running water rinses them away.
Alcohol Hand Sanitizer is safe and effective. It kills almost all the germs (not just the easy to kill ones or the beneficial ones) and it does not encourage the growth of the most dangerous germs. It does not kill most bacterial spores (but, soap doesn't either - friction and running water get rid of those).
It is extensively used in hospitals because it does a good and fast job of killing germs, is fast to use and leaves hands in better shape for most people than soap and water does. BUT, alcohol is for use on hands that are not visibly soiled and not soiled with body fluids or protein (ie, after using the restroom). It kills germs, but it is not a cleaner. So, it can't clean those things off the skin to get to where the germs are.
Antibacterial soap or hand sanitizers that use Triclosan to kill germs are not recommended by Public Health/Infection Control. There are theories/evidence that they lead to the development of resistant organisms (those hard to kill germs). Triclosan kills germs in the same manner as many antibiotics, so use of products containing that have been thought to lead to antibiotics not working as well and there is some evidence to show this is the case.
Alcohol hand sanitizers can have a place in Food Service and are allowed in some states for specific purposes. (Not all states allow it).
But, there are many situations where they are not a good choice and should not be used.
Food Service workers often have wet or damp hands. Alcohol should not be used with wet or damp hands because the alcohol will get diluted and the full 'dose' of alcohol would not get to the hands.
Food service workers also often have protein based material on their hands (things like meat or poultry juices, etc). Alcohol doesn't work well in the presence of protein based material, so hands soiled with those should be washed.
Thanks, Sue. This is very helpful. I was glad to see someone post these guidelines. I edit science and health education textbooks, and often run into issues with writers who want to tell kids that they must wash their hands in HOT water. I can't tell you how many people think I'm nuts when I try to explain that the most important part of the hand-washing act is the *rubbing*. Even if there's no soap, rubbing your hands briskly for 20-30 seconds under running *warm* water will go a very long way.
Anyhoo... Thanks for your clear and thorough post.
