Nearly 230,000 pounds of Spam have been recalled.
The U.S. Department of Agriculture said in a press release some Hormel canned pork and chicken products could be "contaminated with foreign matter, specifically pieces of metal."
The USDA says there are reports of minor oral injuries linked to the recall.
The affected products are Hormel cans labeled "Spam Classic" and "Hormel Foods Black-Label Luncheon Loaf" with a "best by" date of February 2021 and the establishment number "EST. 199N." The products were shipped throughout the U.S. and Guam.
The department urges consumers to throw out any recalled products or return them to the store.
Hormel said the recall affects a limited number of Spam products and apologized in a statement, saying the company takes "consumer and food safety very seriously."
