The federal Food and Drug Administration says Rocky Mountain Popcorn Co. has voluntarily recalled more than 1,600 bags of ready-to-eat low-fat caramel popcorn.

The FDA said Monday an ingredient was found to have a trace amount of tree nuts, which could cause a reaction in anyone allergic to such nuts. The agency said no allergic reactions have been reported.

The recall covers green, nine-ounce bags with UPC number 10449 32050 and with a manufacturing code less than D1231xx.

The FDA says distribution was limited and was mostly in the Denver area.
