A peanut-butter cookie dough recall of products possibly contaminated with salmonella has expanded to school nutrition programs.

Initially, the state public health department thought that 162 public and private schools, including 12 in Contra Costa and nine in Alameda counties, received potentially bacteria-tainted products sent to school fundraising groups.

Because Peanut Corporation of America pushed back its voluntary recall date, the state agencies say that five deliveries of peanut butter to California for use in the U.S. Department of Agriculture commodities program need to be recalled.

Almost 70 school districts in central and Southern California received the commodities, which are used in National School Lunch, School Breakfast, Summer Food Service, and Child and Adult Care Food Programs.

No one has reported any salmonella illnesses related to the recall in California schools, said Dr. Mark Horton, director of the state public health department.
