Kenosha Beef International is recalling almost 90,000 pounds of Johnsonville brand sausages due to consumer reports of metal shards being found with the patties, the U.S. Department of Agriculture's Food Safety and Inspection Service said Thursday.

The products subject to recall are both Johnsonville Grillers, cheddar cheese and bacon flavor, sold in 24-ounce and 13.5-pound cases. All affected products were produced on May 13, 2015. 

The recall has been classified as "Class I," indicating there is a reasonable probability that the consumption of the product will lead to adverse health consequences and even death, reported the Chicago Tribune. Out of the four reported incidents, however, no one has been injured or fallen ill.

Cases of the recalled products bear the establishment number "EST. 425B" inside the USDA mark of inspection on the generic label and possess a "BEST FLAVOR BY" date of Dec. 29, 2015 on the end flap of the package.

All products were shipped to locations in Arkansas, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Ohio, Texas and Wisconsin.

If a consumer finds that he or she has an affected product, they are urged not to eat it and should return it to their retailer for a full refund, or contact customer service by phone (1-888-556-2728) or online at Johnsonville.com.

The FSIS and Kenosha are investigating but have yet to find the source of the metal.
