THE ASSOCIATED PRESS KANSAS CITY MISOURI

Seattle lawyer William Marler has filed a lawsuit in Kansas City for a Missouri family that became sick after eating peanut butter.

William Marler says the lawsuit filed today in federal court is the first in the salmonella outbreak that has sickened nearly 300 people in 39 states.

Brian and Susanna Cox of St. Joseph and their two children became sick in October after consuming Great Value Peanut Butter purchased at a Wal-Mart Superstore.

The outbreak has been traced to certain batches of that brand and Peter Pan peanut butter, both manufactured by ConAgra Foods.
