(NEXSTAR) – Nearly 162,000 pounds of select Skippy peanut butter products are being voluntarily recalled because some of the jars may contain small fragments of stainless steel.

Skippy Foods announced the recall Wednesday evening, saying roughly 9,350 cases of three products with specific code dates are affected. The stainless steel fragments are from a piece of manufacturing equipment.

Below is a list of the affected products and their corresponding code dates, which are found on the top of the lid.

According to Skippy, internal detection systems at the manufacturing facility were able to detect the equipment issue. There have not yet been any reports from consumers about fragments found in the peanut butter.

Instead, Skippy said it is voluntarily recalling the affected products “out of an abundance of caution” and to “ensure that consumers are made aware of the issue.”

The company says the recalled peanut butters were sent to 18 states: California, Connecticut, Delaware, Florida, Hawaii, Illinois, Indiana, Kansas, Massachusetts, Minnesota, Missouri, North Carolina, Nebraska, New Hampshire, New Jersey, New York, Oklahoma, and Wisconsin.

No other Skippy products are included in this recall.
