Hi, Can anyone tell me who needs a food handling license, restaurant owner? food preparer? I'm a little bit lost...help. Thanks 

California may be different than Kansas. It may vary from county to county. Your local Heath Department will have the best answer.

I don't know where you are, but in Michigan you need one person per shift in the kitchen who is serve-safe certified.  As mentioned before, your best bet is to contact your local health department.
