Chinese couple's meat turns to blue color and glows in the dark.

It was only after they had hung the remains of the carcass on their kitchen wall for safekeeping that they noticed the meat was emitting a strange, blue glow, the Daily Mail quoted.
The likely cause is a type of fluorescent bacteria.
Last year a number of residents in Changsha city discovered that the pork they had purchased from a supermarket emitted a blue glow at night.
Health officials were called in and were able to establish that the blue light was created from secondary bacterial contamination.
