Chemical reactions by bacteria breaking down food produce light, enough for humans to see in only the darkest of places (if you live in a city, you won't ever encounter dark enough situations). Some city folk have doors and window shades. My old apartment kitchen was on the windowless side of the apartment with a door. If you close the door (and unplug the microwave), it was pitch black. Though I never saw any glowing food, not even the spoiling fruit on the counter.
