The Center for Disease Control (CDC) is instructing people not to eat Kellogg’s Honey Smacks cereal.
Last month, the company recalled more than a million cases of the cereal because of concerns that it may be contaminated with salmonella.
The Federal Drug Administration (FDA) says it has received reports of some retailers still selling the cereal.
At least 100 people in 33 states have come down with salmonella after eating Honey Smacks. 30 of those people were hospitalized, but no deaths have been reported.
