Is that milk past its 'sell by' date? Drink it anyway.

This is probably one of my biggest pet peeves in the industry and I hope on Food Recovery Lobby Day on Apr 4, 2016 we address this issue. "My father used to keep food in the refrigerator for days, even weeks after the “best by” date, so long as it looked and smelled OK. My mom, by contrast, went out to buy a new carton of milk as soon as the date passed. Often there would be two containers of milk in our refrigerator: the half-empty one my dad was committed to finishing, and the new one my mom had purchased, out of fear that she might get sick if she drank my dad's past-date milk."
