The adult film industry in Los Angeles looks set to resume after a porn actor who tested positive for HIV was retested with negative results.

The initial positive test forced a week-long shutdown of adult video production in the city. Production has been shut down since last week in the San Fernando Valley's multi-billion dollar adult entertainment industry, which includes Hustler and Evil Angel's productions.

The name and gender of the performer was not released but it was revealed that the individual tested positive for HIV in Florida. The actor had been slated to work on a shoot for Mofos.com.

The star in question underwent further testing to confirm the results, but has now been cleared of the disease.

Adult video performers are required to be tested for HIV every 30 days and show their most recent test results before performing.

The AIDS Healthcare Foundation, the world's largest AIDS organization, is attempting to have a measure placed on Los Angeles' June 2012 ballot that would require adult video performers to use condoms.

Free Speech Coalition is working on a database to follow sexually transmitted disease testing among porn actors, a task formerly handled by the Adult Industry Medical Healthcare Foundation before it closed in December 2010.

The porn industry was in the same way closed down in late 2010, after porn actor Derrick Burts was diagnosed as HIV positive. His case was confirmed, and he has since left the industry to become an advocate for the use of condoms in pornography.
