The announcement from the Free Speech Coalition (FSC), an industry trade association, came after the CDC advised people nationwide to cancel or postpone gatherings of more than 50 people and after California and other states called on nonessential businesses like bars and restaurants to close.

“We ask that producers cancel all shoots through March 31, and recommend that performers immediately stop filming with partners who are not a part of their household,” the FSC said in a statement.

The call to shut down affects the roughly 2,000 performers and the majority of porn production companies in North America that use the FSC’s PASS testing system, which screens for sexually transmitted infections, FSC communications director Mike Stabile told BuzzFeed News.
