That just reminded me of a story my buddy who used to work at walmart told me.

Apparently, an HIV positive man came into the store with a knife and slit his own wrists in the produce section. He then proceeded to spray or fling his blood all over as much produce as possible, before being arrested/restrained and taken to the hospital.

A hazmat crew and to come in and dispose of all the produce in the store, tent off the area and sterilize it.
