A few days before Memorial Day weekend, the unofficial start of the grilling season, Vienna Beef has recalled 2,030 pounds of beef hot dogs out of concerns they might contain pieces of metal.

The 126-year-old Chicago-based business realized the problem and reported it to the the U.S. Department of Agriculture’s Food Safety and Inspection Service, the USDA said on its website.

The 203 10-pound packages of beef frankfurters were sold to restaurants in Illinois, Indiana and Wisconsin and were not available directly to consumers through supermarkets or online grocery stores, Vienna Beef's vice president of marketing Tom McGlade said.
