Seattle food-safety attorney Bill Marler, who filed the lawsuit on behalf of a Kennewick, Wash., family who fell ill after eating Paramount-produced almonds, said there could be more lawsuits to come against Paramount.

Marler said his firm, Marler Clark, which specializes in foodborne illness litigation, is currently investigating 250 claims "directly connected" to almonds.

The almond giant voluntarily recalled 13 million pounds of raw almonds after the U.S. Food and Drug Administration reported 25 cases of salmonella linked to the product, but the number of consumers who say they were sickened by salmonella-tainted almonds has risen to 29.
