What about cooking? e.g. handling raw meat and such?
You don't need to kill the bacteria. Just remove it.
I'm pretty sure the lipid-dissolving properties of soap kill bacteria by shredding their cell membranes. It's not effective against viruses, but neither is antibacterial soap.
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.
