Posters warning people about human trafficking and telling victims how to get help will be going up at adult entertainment venues and massage parlors in Palm Beach County.
The new ordinance will become law on January 1st.
"We thought slavery was gone a very long time ago in America. But unfortunately we have slaves here right now," Linda Geller-Shwartz with Partner Organizations Against Sex Trafficking said.
Geller-Schwartz helped get the new ordinance approved.
The poster she helped design in three languages will be displayed at the adult venues.
"It wasn't easy to get the law passed. And when we did it we were jubilant because we knew awareness was the most important thing," Geller-Schwartz said.
Some adult entertainment clubs already have signs up warning of human trafficking.
Monroe's management in West Palm Beach says they've had signs up for about six months.
"If we see anything that might look wrong, we contact authorities. But you don't see it very often," Monroe's owner Scott Lizza said.
Lizza said his club will proudly put up the new posters.
Geller-Schwartz says they will be doing checks to make sure all the clubs have the posters.
