The Quaker Oats has recalled some granola bars and cereals over concerns they could be contaminated with salmonella.

The products – which include Quaker’s popular chewy granola bars and puffed granola cereals – were sold in every state, according to an announcement by the Food and Drug Administration. The products could potentially be contaminated with salmonella, an organism that can cause serious and sometimes fatal infections in young children, older people or those with weakened immune symptoms. Healthy people infected with salmonella often experience fever, diarrhea, bloody stool, chills, nausea, vomiting and abdominal pain.

Symptoms of infection usually occur 12 hours to three days after exposure and infections generally last a few days to a week.

Quaker said it has received no confirmed reports of illness related to the products.
