Sorry, Askold, but no. It has nothing to do with food safety in the slightest. There are several states where its outright illegal to feed the homeless. I think the only way around it is by getting a special permit and running a soup kitchen (or something along those lines), which even then, would likely be very difficult to acquire since you're helping icky homeless people not starve to death. The homeless aren't seen as unfortunate people who are already suffering enough, they're seen as tarnish on a city's (or state's) glistening facade. They make them look bad, so they try to hide them away and/or kill them instead of helping them, ya know, not be homeless by giving them a place to stay.
