Details emerge on Bravo's STD contracts

Joining a reality show involves a lot of paperwork -- and you'd better read what you're signing.

Cast members of Bravo's hit reality shows must sign a "STD clause," ensuring that the network isn't legally responsible if its stars contract sex-related diseases or infections throughout production, according to Page Six.

Bravo is home to programs including "Vanderpump Rules," the "Real Housewives" franchise and "Summer House." It's unclear whether the "STD clause" is included in shows like "Top Chef" that don't spotlight cast members' dating lives.

Networks have chosen to handle the sticky issue in different ways. Over at ABC, contestants on "The Bachelor" and "The Bachelorette" must be screened for STDs. And the tests aren't just for finalists -- the top 50 competitors are all required to get checked.

“It’s the sexiest STD-free dating pool on Earth,” "Bachelor" alum Jesse Csincsak told HollywoodLife in 2011. “They make you pee in a cup and draw blood. If you have virus, you’re not going on the show.”

And in 2010, "Jersey Shore" creator SallyAnn Salsano told THR that producers distributed herpes medication to the cast "like M&Ms."
