A lawsuit has been filed by Seattle lawfirm Marler Clark on behalf of the family of Ruby Trautz, an elderly woman who died after eating E. coli-contaminated spinach.

The estate is suing Dole Food Co. of Westlake Village, Calif.; Natural Selections Foods of San Juan Bautista, Calif.; No Frills Supermarkets of Omaha; and the undisclosed California farm where the spinach was grown, according to the Bellevue News-Leader.

According to the lawsuit, Trautz ate Dole brand baby spinach, which Nebraska public health officials linked to a national E. coli outbreak that sickened 204 people and caused three deaths. Natural Selections Foods bagged the spinach.

Bill Marler, the attorney representing the Costello family and 93 other people who were sickened as part of the outbreak, posted about today’s announcement that one of four farms who supplied Natural Selections Foods and Earthbound Farms with spinach had been identified on his blog.
