Every day we drive to the (giant)
local store of a major grocery store company chain. We pick-up all their, fresh from the cooler, discard produce. This includes boxes of strawberries with often only one single overripe berry. Or packages of nuts that have reached expiration date, but are perfectly fine. Or huge bags of lettuce leaves pulled from lettuce heads (that we feed to the
chickens and
rabbits). We get perfect bottles of juices and other drinks, and unopened boxes of celery, potatoes and bags of onions and much more. It is absolutely incredible what they throw away. We haven't bought a single bit of produce or fruit for us, the many pigs we raise (we give them no grain because there's so much) or the rabbits. The
cattle, goats and
chickens even sometimes benefit. At first the local store didn't want to donate, but we called the national headquarters and got permission and they told the local outlet to do it (headquarters liked the recycling and reduced dumpster use). ....The watermelons and cantaloupes are also always good. There's so much (a good bit of which is marked "organic") that we can and freeze lots for latter. The store also gives away all its baked goods and bread to a local homeless
shelter. And other items to a woman's shelter. So depending on your local store and situation there are all kinds of things being given away every day. Just ask. (We also give quite a bit of what we get to a number of friends and family because we often pick-up too much. Feeding folks is good.)
We have also at times picked up 5 gallon buckets of all the uneaten meals and meal leftovers from the National Park Eco Education Center, a local private school and the local private summer camp. They all also like recycling their food stuffs instead of dumpster'ing it. They get to claim how earth friendly and socially conscious they are, we get free food for the animals (and sometimes us).
There are also local farm field gleaner groups you might connect with. Or start one yourself. They are great benefit to local food banks. There is absolutely no reason for any food to be wasted if local farmers and groups make the effort to recycle it. And the economic benefits to user of the give-a-way's can benefit hugely.
