It’s now an Occu-sty. Feces, vomit, tampons, urine and the flies that love them all have soiled Justin Herman Plaza since Occupy SF moved in, according to city officials.

A letter from The City that was recently distributed at Justin Herman Plaza warns that the encampment is an “imminent public health hazard.”

The letter offers grimy accounts of the many bodily fluids seen by public health and park officials.

“Several piles of vomit were observed along the side of the park,” according to the letter. “Pile of feces and tampons found at a nearby pathway."

In a statement, Occupy SF said The City is creating "a sanitation problem by design," partly because it only allows portable toilets to be acceesed during the day.

The camp on Tuesday evening received a letter from San Francisco police Chief Greg Suhr saying participants are subject to arrest.

Police had not made any moves to break down the camp Wednesday morning.
