The CDC has urged consumers not to eat Honey Smacks "in any size packaging" and to throw opened or unopened boxes in the trash even if some of the cereal had been eaten without people falling ill.
"Retailers should not sell or serve Kellogg's Honey Smacks cereal", the CDC says.
The FDA said on Thursday it would follow up with retailers to prevent the sale of the product.
One hundred people in 33 states have been sickened by a salmonella outbreak linked to Kellogg's Honey Smacks cereal, the CDC reported Thursday. Though the recall covers cereal with a best-by date of June 14, 2018, through June 14, 2019, the agency is recommending people avoid the cereal altogether.
Illnesses were first reported on March 3, and the most recent case was found on July 2. The agency revealed that 27 more people from 19 states were infected from the outbreak since the last update on June 14.
Kellogg Company, which did not respond to an immediate request for comment, launched an investigation into a third-party manufacturer who produces the cereal in mid-June after the infections were reported, according to the FDA.
The CDC said lab tests identified Salmonella Mbandaka in a sample of unopened Honey Smacks cereal from a store in California.
Additionally, if you stored the tainted cereal in any kind of a reusable container you'll need to wash and sanitize that container before you use it again. Sick people should tell their doctors about their possible exposure to Salmonella because special lab tests are required to properly diagnose the infections.
