Bread

From Trashwiki

Bread can often be found not only at bakeries, but at other places, too, since many shops selling bread tend to ridiculously overstock, that's why bread (often in alarming quantities) can be found in many dumpsters.

When there's mold on bread you should leave it (or throw it out), "porous foods can be contaminated below the surface" [1].

There is a rule in both Judaism and the Islam that people should not throw away food. In Jerusalem you can find random bags of bread right in the street.
