Utah residents in West Jordan are fed up with a foul odor they say is coming from the Dannon yogurt plant. Maurie Vance created a petition on change.org, urging city, county and state officials to work with residents and Dannon to find a solution to the smell.She describes the smell as being obnoxious and says it is at its worst during the fall and winter months.“It’s like a sour milk, dirty diaper — disgusting,” Vance said.The petition has received hundreds of signatures.“It gags you so much, you don’t go outside. You run back into your house,” said West Jordan resident Dana Grandy.
