DUNDEE, Ore. (AP) — A worker at a winery southwest of Portland died earlier this week after collapsing while cleaning manufacturing equipment, officials said.

The Oregonian/OregonLive reports 39-year-old Armando Aguilar-Yanez, of McMinnville, was found unconscious at the 12th and Maple Winery Co. in Dundee around 10:30 a.m. Monday, according to Sgt. Brian Hagen, a Newberg-Dundee Police Department spokesman.

He said workers and emergency crews attempted to resuscitate Aguilar-Yanez, Hagen said, but were unsuccessful.

An initial investigation by police has found no evidence of foul play, Hagen said in a statement.

Aaron Corvin, a spokesman for the Oregon Occupational Safety & Health Administration, said the agency is investigating the death but said he couldn’t comment further until the investigation was complete.

It was unclear what caused Aguilar-Yanez to lose consciousness and a call to the Yamhill County Medical Examiner was not immediately returned.

A winery representative declined to comment.
