A report to the Minneapolis City Council has highlighted health concerns with the city's adult entertainment venues.
The Minneapolis Health Department conducted a sweep of 17 venues across the city and found "stains of concern" in 16 of them.
These stains were tested and traces of semen were found in swabs taken from 11 of these establishments, according to a report going before the city council's Health, Environment and Community Engagement on Monday.
Traces of bodily fluids were found at three other venues, but couldn't be confirmed as being semen. Two of the other establishments that initially had "stains of concern" were later found to be clean.
The three adult venues that are given a clean bill of health by inspectors were: BJ's Liquor Lounge, the Eagle Bolt Bar and Saloon.
The department says that this represents a public health concern given that semen found in public places is considered a "potentially infectious material."
The Star Tribune reports that all but one of the 11 venues where male bodily fluids were found have private or semiprivate areas, including private booths to view adult films and beds where customers get private dances. Swabs were taken from chairs, couches, floors, walls and bedspreads.
The 11 clubs or stores have been served with letters from the health department ordering them to properly clean their properties and take measures to prevent the same issue in the future.
The health risks to exotic dancers
Studies have found that exotic dancers are at heightened risk of contracting sexually transmitted disease, according to the CDC.
A study of Baltimore strip clubs in 2011 found that in multiple cases, exotic dancers were found to be illegally selling sexual services to customers, often at the encouragement of management.
Even though most would demand condom use, the illegal nature of sex work "greatly minimizes" dancers' negotiating power, and dancers with drug addiction in particular were more likely to agree to forego condom use if it meant they got paid more money.
The blog Thought Catalog spoke to a number of strip club workers and dancers about their respective club's cleaning regimen, and found mixed results, with some clubs taking a strict approach to cleanliness and others ... not so much.
