Hash browns sold under the Harris Teeter and Roundy's brands have been recalled for an unusual reason: possible golf ball contamination.

The Food & Drug Administration's recall notice says that McCain Foods USA, Inc. has voluntarily recalled frozen hash browns sold under the Harris Teeter and Roundy's brands because they may be "contaminated with extraneous golf ball materials, that despite our stringent supply standards may have been inadvertently harvested with potatoes."

The FDA warns consumers that, "consumption of these products may pose a choking hazard or other physical injury to the mouth." No injuries have been reported, according to the FDA.

The recalled products include Roundy’s 2 lb. bag of frozen Southern Style Hash Browns (UPC 001115055019) and Harris Teeter’s 2 lb. bag of frozen Southern Style Hash Browns (UPC 007203649020). The recalled products were manufactured on January 19, 2017 and bear a production code date of B170119.

The Roundy’s products were sold at Marianos, Metro Market, and Pick ‘n Save supermarkets in Illinois and Wisconsin. The Harris Teeter products were distributed in North Carolina, South Carolina, Virginia, District of Columbia, Delaware, Florida, Georgia and Maryland.
