It is actually more important to wash your hands properly than it is to use antibacterial soap. This is why most restaurants and medical facilities teach folks how to do it - and why some places install timers on their sinks. Basically, you need to lather for 10-15 seconds, making sure to get between the fingers, top part of the wrist, and your fingernails.

I've heard this action is actually more important than the soap bit for the anti-bacterial properties. But soap helps remove things like grease and 'juice' from the meat really well and helps us be less lazy when doing so.
