Marler Clark, the Seattle law firm that has represented thousands of victims of Salmonella and other food poisoning outbreaks, filed a lawsuit today against Iran Echo International Corp., the owner of the Pars Cove Persian Cuisine booth that was identified as the source of a large Salmonella outbreak at this year’s Taste of Chicago festival. The lawsuit was filed in Cook County Circuit Court on behalf of Kenneth and Donna Searcy, a Romeoville, Illinois, couple who ate food from the Pars Cove Taste of Chicago booth on July 2, and subsequently became ill with Salmonellosis.
