Which products were recalled? In total, 13 canned tuna products were voluntarily recalled, according to the announcement.

With 90% of the U.S. population living within 10 miles of a Walmart store, recalls of products they sell can have widespread effects. Labeling mistakes, safety concerns and contamination can all cause food recalls. Prescriptions and other products can also be recalled.

Tuna sold in 26 states and in Washington, D.C., was recalled over concerns that it may have been contaminated. The stores affected include Trader Joe’s, Genova, Van Camp’s and H-E-B.
