The parent of the Jack in the Box fast-food chain has agreed to accept $58.5 million from nine beef suppliers to end litigation filed after tainted hamburger killed four people in 1993.

The deal with Foodmaker Inc. ends a string of court battles, including nearly 100 lawsuits filed on behalf of people who ate burgers contaminated with an especially virulent strain of E. coli bacteria. Hundreds were sickened.The outbreak eventually was traced to several Jack in the Box outlets in Washington state. Foodmaker sued its supplier, The Vons Companies Inc., and eight companies that sold beef to Vons.
