The Centers for Disease Control and Prevention says a popular Kellogg's cereal has been linked to a salmonella outbreak. According to the CDC, 100 people in 33 states have been affected. The CDC announced Thursday that customers should avoid Honey Smacks. The agency says it found salmonella in samples of Honey Smacks, which has been subject to a voluntary recall by Kellogg since mid-June. It says that regardless of expiration date, the cereal should be thrown away or returned to a retailer for a refund. People infected with salmonella develop a fever, cramps or diarrhea within 12 to 72 hours of being exposed to the bacteria.
