needle(medical)*Uh oh, his is not good news for the adult film industry (and EUR faithful & porn fanatic TesticAl, who likes to “hit it raw”).

On the other hand, it could be the perfect excuse to strap up and use condoms as some are now advocating.

In fact it’s been mandated by the city of Los Angeles, but was met with, er, stiff resistance. But now that attitude might be changing.

Four more cases of syphilis have been found in an investigation of an outbreak among porn performers, bringing the total to nine, and the discovery of more cases is likely, Los Angeles County’s top health official said Tuesday.

Five cases were reported last week, causing a trade group for the multi-billion dollar industry to call for a halt in filming to prevent the spread of disease.

“It’s not surprising in the adult film industry that we would have transmission of all sexually transmitted diseases because they’re having unprotected sex, oftentimes with multiple actors,” said Dr. Jonathan Fielding, director of the Los Angeles County Department of Public Health.

The current number of syphilis cases in the most recent outbreak “will grow,” said Fielding, adding that an ongoing investigation is expected to uncover more cases. The latest discoveries were made through testing of the sexual partners of the earlier cases found, he said.

All those infected are also in the industry, but it remains unclear whether they contracted the illness on- or off-set, he said.

The Free Speech Coalition called for a nationwide filming moratorium this weekend, telling performers to get tested for syphilis and to get penicillin shots before returning to sets. After performers get the shots, they can go back to work within 10 days, said FSC spokeswoman Joanne Cachapero.
