Approximately 228,614 pounds of Spam have been recalled after metal pieces were found inside some cans, the US Department of Agriculture announced on Saturday.

At least four people told Hormel Food Corp. that they found metal pieces in the canned meat product. There were reports of “minor oral injuries” caused when the contaminated Spam was consumed, according to the USDA.The FSIS did not say how the pieces of metal might have gotten into the products.

12-ounce metal cans labeled “SPAM Classic” with the designation “EST. 199N” should not be eaten because of a risk of minor oral injuries, FSIS said. The cans have a “Best By” date of February 2021 and carry the following production codes: F020881, F020882, F020883, F020884, F020885, F020886, F020887, F020888 and F020889.

Possibly contaminated cans of meat were also distributed in Guam. These 12-ounce metal cans contain “Hormel Food Black-Label Luncheon Loaf.” The recalled cans are marked “Best By” February 2021 and carry the production codes F02098 and F02108.

It is recommended that the products in question should be immediately thrown away or returned to the place of purchase, FSIS said. In a statement, Hormel said it was recalling the products “out of an abundance of caution,” and that “the health and safety of consumers is our top concern.”
