Despite concerted efforts to stop the illegal activity allegedly associated with the mobile stands, Multnomah County health inspectors and Portland police did not issue citations to unlicensed hot dog vendors outside music venues last weekend.

County officials said last week that efforts to get hot dog vendors to voluntarily comply with health orders have failed in recent months. They warned that the stands also sold alcohol to minors and said there was no evidence that some vendors might be victims of human trafficking. Last year, county officials said they shut down four vans that parked mobile hot dog stands.

The district said it had again observed unlicensed dealers “at several events” over the weekend, but this time it had refrained from issuing tickets.

“This action was aimed at raising awareness,” district spokeswoman Sarah Dean wrote in an email. She referred questions about human trafficking to Portland police, who said they did not issue citations or make arrests during the weekend hot dog operation.

“We are still in the early stages of investigating whether human trafficking is taking place and which of our community partners can assist in this matter,” police spokesman Mike Brenner wrote in an email.

The county will work with the city and other agencies to continue to address the issues surrounding hot dogs, Dean said, but did not announce any additional control measures.
