A voluntary moratorium on adult film production in Los Angeles was lifted Sept. 3 after a performer whose positive test for the virus that causes AIDS was found to be still HIV-negative, a porn industry trade group told Associated Press.

After an adult film performer tested positive for the HIV virus linked to AIDS, the porn industry temporarily suspended film production throughout Los Angeles Aug. 29 pending more testing, the Los Angeles Times had reported.

Diane Duke executive director of Free Speech Coalition (FSC), a private non-profit advocacy group for the adult entertainment industry in Canoga, Calif, told the AP that production can now resume. “The industry will be abundantly cautious as we try to nail down the reasons for what now appears to have been a false positive result on a previous test,” Duke said.

The actor, who was in Florida, was to work on a shoot for Mofos.com, but production was halted last week when the test came back positive for HIV.

The billion-dollar industry initially learned of the scare when the FSC, disseminated information about the positive test to porn companies. At least 13 people could have been exposed to HIV had the test results been confirmed, according to Michael Weinstein, president of the AIDS Healthcare Foundation (AHF).

AHF said a monthly protocol is mandated by the industry, which requires performers to come to work with “less-than-30-day-old STD results.”

“Testing is not a form of prevention … They’re more likely to pass the virus during that period when they’re first infected. There’s a maximum danger level. No amount of testing is going to eliminate that possibility,” Weinstein told LA Weekly.

“We also want to put pressure on the Free Speech Coalition to come clean about what’s going on,” Weinstein said.

The FSC’s Duke said they found out about the positive case Aug. 27, and did not try to cover it up, as AHF is reported to have suggested.

FSC has asked AHF to retract the cover-up assertion. “There is no cover-up, as we have been accused of by AHF. In fact, we were the first to officially go public with the situation late on Sunday … We called for the moratorium in order to minimize any risk of exposure …”
