Highway to Hell, one of the West’s most popular wedding songs, took on added meaning when at least 22 guests were stricken with Salmonella at a winery in Arizona.

Pinal County’s Public Health Services District say they’re investigating the outbreak that’s linked to a March 19 wedding at the Windmill Winery.

The district received a call from a participant of the wedding who reported that at least four attendees needed to be hospitalized.

County public health officials began an investigation into the winery’s food practices and found the operators had exceeded their legally allowable level of food preparation and used a non-permitted caterer.
