That's the frank message the Centers for Disease Control and Prevention had for lovers of the breakfast staple Honey Smacks on Thursday after 100 people were infected with salmonella and 30 of them hospitalized.
A sign hangs outside the Kellogg's factory near Manchester, Britain March 7, 2016.
"Do not eat any Kellogg's Honey Smacks cereal, regardless of package size or best-by date", it said.
The FDA said on Thursday it would follow up with retailers to prevent the sale of the product. The Kellogg Company recalled the cereal on June 14, 2018. "Additionally, the public is urged to report any product being offered for sale to the FDA Consumer Complaint Coordinator in their region".
"Laboratory testing identified the outbreak strain of Salmonella in unopened and opened boxes of Honey Smacks cereal collected from retail locations and from ill people's homes", the new report stated.
The sugary puffed wheat cereal has been the subject of a recall by Kellogg's since mid-June.
Retailers should not sell or serve Kellogg's Honey Smacks cereal. Customers should either throw away the product or may return their box of cereal to a store for a full refund.
This comes as the federal agency continues to investigate a multi-state outbreak of Salmonella. No deaths have been reported, the CDC said.
Common effects of salmonella is the result of a fever, cramps, or diarrhea within 12 to 72 hours of being exposed to the bacteria.
Symptoms last about four to seven days, and although most people improve without treatment, some may require hospitalization because of severe diarrhea.
