You need to consult an attorney.
He or she can help you sort through federal/state/local laws and regulations governing everything from content labeling, health codes, etc to tax and insurance issues (You do need to have lots of insurance.) and, like Uncle Bob suggests, organizational issues, like LLC's, etc. Hiring an attorney may seem expensive (it need not be), but it's the best way to get the information you need to know before you make a decision.
It is very difficult to start up a successful food business. The costs of doing do are very high.
Do your homework thoroughly before making a decision and good luck either way!
