Sacramento, Calif. ? Federal prosecutors say buyers for Kraft Foods Inc. and Frito-Lay Inc. are pleading guilty to taking bribes from a California-based tomato processor.

Prosecutors say the men helped drive up food prices nationwide.

Robert Watson of White Plains, N.Y., entered his plea in a Sacramento federal court Tuesday to accepting $158,000 from a sales broker at SK Foods of Lemoore. The 59-year-old Watson was a Kraft senior purchasing manager.

The U.S. Attorney says 58-year-old James Wahl Jr., a former Frito-Lay purchaser from Dallas, also has agreed to plead guilty to accepting about $160,000.

The charges say they each helped SK Foods charge their companies inflated prices.

Watson’s attorneys did not immediately return telephone messages. No attorney is listed for Wahl.
