Frito-Lay announced Saturday a recall of 1,576 cases of Peanut Butter Bars that the company said may contain salmonella bacteria. The bars were shipped to 22 states west of the Mississippi River, including Utah.

Beverly Holmes, spokeswoman for the food company, said the bacteria was discovered during testing of a random sample of the candy bar at the company's laboratory in Dallas. The federal Food and Drug Administration was notified of the test results and the recall, she said.Holmes said the chances were small that any of the bars would reach consumer shelves, or if eaten, that a specific candy bar would make a person ill.

The bars possibly tainted with the bacteria carry product date codes of 19 DEC 88 and 26 DEC 88, printed in white ink on the front of the package. Holmes said Frito-Lay salespeople were alerted to the recall and were working with retail outlets to stop the sale of the bars.

In addition to Utah, other states receiving shipments of the bars were identified by the company as Arizona, Arkansas, California, Colorado, Idaho, Iowa, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Washington and Wyoming.
