Listeria infections can cause mild illness including fever and diarrhea or more serious problems. The illness is most dangerous to pregnant women, newborns, adults over 65 and people with weakened immune systems, according to the U.S. Centers for Disease Control.
The CDC estimates that 1,600 people are infected with listeria each year in the United States and 260 die.
The recalled waffles are sold under a variety of names including Walmart's Great Value, Target's Good & Gather and private label brands sold by Food Lion, Kroger and Schnucks. TreeHouse published a complete list.
TreeHouse said there have been no confirmed reports of illness related to the waffles.
The company said consumers holding any of the products should dispose of them or return them to the store for credit.
