[COLOR=333333]Good points. Id also like to mention that when I attended PU, we always used these when going to the farms. I'd think if they didnt have any benefit what so ever, I would have thought PU would have known and not wasted money (be it my tuition money, but still lol). Now you got me curious, Kiniska. Are you in the healthcare field or a mad scientist

Not a mad scientist, well unless I have been up set. 
[COLOR=008000]I work in medical research and mice are involved. [/COLOR]
[COLOR=008000]All the points being made about these shoe covers are appreciated. As for a facility using them well... Hospitals use them, research facilities use them, and chemical plants use them. Just because everyone does something does not mean it actually works. Really depends on situation, but in the application you all want to use them everyone needs to be aware that they won't be effective. It would be awful if someone thought they were protecting their flock and instead infected it. [/COLOR]
[COLOR=008000]I hate that shoe covers are used at some of our facilities at work. Shoe covers, in many instances, are more a liability than a help. Shoe covers are one of those things that have been used for so long without testing to prove their worth that they have become a fixture. Recently testing has been done that has shown how ineffective they are. Where I work the vendors take the guy who does our protective equipment purchasing out to eat and they give him tickets to shows etc.... So even though we all know they are useless and half of us don't use them the facility still buys the things.
Take this example. The first surgeon who decided all medical equipment should be sterilized in between patients was thought a mad idiot by his colleges. He knew he was right, he had concrete numbers to back it up, but it took years for the medical community to acknowledge it and thousands of people died from secondary infections until his findings were acknowledged. Now if a doctor came at you with a dirty needle or crusty scalpel any of us would loose our minds on them. It is considered "common" knowledge that things have to be sterilized. [/COLOR]
[COLOR=008000]If you guys want to use shoe covers that is your choice, just be aware that they may not do what you hope they will. What will be very effective is dedicated shoes, like rubber crocks, that can be bleached and sanitized regularly. [/COLOR]

[COLOR=008000]Forgive me, I really hate shoe covers. [/COLOR]
