Most stabilized countries have laws in place for food and protections for donations.

I'm guessing there's rules behind this one but in the US:

The Food Donation Improvement Act: This act expands those protections. It allows qualified businesses (like restaurants, supermarkets, and schools) to donate food directly to individuals in need rather than having to route it through a registered 501(c)(3) nonprofit intermediary. It also allows nonprofits to charge a nominal "Good Samaritan" fee just to cover the logistics and handling costs of distributing the food.

I don't know the specifics of that one though.
