Hello!
Either you have not registered on this site yet, or you are registered but have not logged in. In either case, you will not be able to use the full functionality of this site until you have registered, and then logged in after your registration has been approved.
Registration is FREE, so please register so you can participate instead of remaining a lurker....
Please note that the information requested during registration will be used to determine your legitimacy as a participant of this site. As such, any information you provide that is determined to be false, inaccurate, misleading, or highly suspicious will result in your registration being rejected. This is designed to try to discourage as much as possible those spammers and scammers that tend to plague sites of this nature, to the detriment of all the legitimate members trying to enjoy the features this site provides for them.
Of particular importance is the REQUIREMENT that you provide your REAL full name upon registering. Sorry, but this is not like other sites where anonymity is more the rule.
Also your TRUE location is important. If the location you enter in your profile field does not match the location of your registration IP address, then your registration will be rejected. As such, I strongly urge registrants to avoid using a VPN service to register, as they are often used by spammers and scammers, and as such will be blocked when discovered when auditing new registrations.
Sorry about all these hoops to jump through, but I am quite serious about blocking spammers and scammers at the gate on this site and am doing the very best that I can to that effect. Trust me, I would rather be doing more interesting things with my time, and wouldn't be making this effort if I didn't think it was worthwhile.

I don't think they are all that effective, and I think they make us feel better to have them at shows.

c) Technique is still important. Most people don't wash effectively (for antimicrobial reduction), and they don't use sanitizers effectively either. The process needs to involve a sufficient amount of sanitizer, and reasonably brisk rubbing of then hands...care needs to be taken to include ALL surfaces, ie between fingers, fingertips, and nails.
I'm sure I can dig up multiple studies that show a reduction of microbes with proper use of hand sanitizers...but it bears pointing out that there will always be the occasional cases that don't show improvement or show increased presence, and that some pathogens aren't likely to be significantly impacted with the small exposure time of "normal" hand cleaning.

Jerry,
You may want to share Harald's excellent reply. To put it in very simple terms: "soaps clean, sanitizers kill", the combination of both procedures provides for a better sanitation.

Where did the research say "(Hand) Sanitizers Kill?" I read it as it stripped the oil from our skin.

How do hand sanitizers work?
Hand sanitizers work by stripping away the outer layer of oil on the skin. This usually prevents bacteria present in the body from coming to the surface of the hand. However, these bacteria that are normally present in the body are generally not the kinds of bacteria that will make us sick. In a review of the research, Barbara Almanza, an associate professor at Purdue University who teaches safe sanitation practices to workers, came to an interesting conclusion. She notes that the research shows that hand sanitizers do not significantly reduce the number of bacteria on the hand and in some cases may potentially increase the amount of bacteria on the hand.

Oh, Harald...I was going by your statement here:

Deb,
Hand sanitizers are mostly alcohol-based. Because of this reason they will in effect remove the oil from your skin (fat is soluble in alcohol) but at the same will kill in one minute nearly all bacteria and viruses by disrupting the cell membrane.

There are other studies showing handwashing is more effective. I'm not making choices for anyone, but at least some people are showing enough concern that they are thinking about the consequences of going to shows and possibl handling various critters, and then returning home to their collections.

No doubt they serve to reduce the risk of transferring disease, etc., I just doubt that they are as effective as we are led to believe. I use hand sanitizer at home when going from cage to cage while feeding and/or cleaning, but I don't consider it a complete safeguard against anything.

No, they can't to magic, the dirtier the hands are the less effective they will be. That's why Harald's response was right on the money, particularly his thrid point:

(to the bolded) Exactly...the more people that are aware of this, the more they can guard themselves.
