A Denver judge has wrapped up most of the wrongful-death lawsuits stemming from a 2011 listeria outbreak traced to a cantaloupe farm that killed more than 30 people and sickened more than 140 others.

The Denver District Court judge approved settlements for the families of 30 of the 33 people who died. The relatives sued companies that handled or sold the melons. Twenty lawsuits from those who fell ill also were settled.

Plaintiffs’ attorney Bill Marler said details of proposed settlements are confidential. Medical expenses from those cases total more than $12 million, Marler said Wednesday.

“This was a very complex case, involving people in 20 courts in 12 states. It has been more than three years now,” Marler said.
