The warning came less than a month after the company launched an investigation with the third-party manufacturer who produces the cereal after being contacted by the Food & Drug Administration and CDC regarding reported illnesses.

The CDC says that regardless of the expiration date, any Honey Smacks cereal should be thrown away or returned to a retailer for a refund.
"Retailers can not legally offer the cereal for sale and consumers should not purchase Kellogg's Honey Smacks cereal", the agency said in a statement.
The CDC warns the public not to eat any Honey Smacks cereal from any size package and with any "best if used by" date.More news: China-made medicines with Valsartan to be withdrawn
All Honey Smacks products that were on the market within the cereal's one-year shelf-life have been recalled. Samples of the facility's environment and the product collected during the FDA's inspection match the outbreak strain of salmonella mbandaka, the agency said.
The agency has said that it has found salmonella stains in unopened and leftover samples of Honey Smacks. Though the official recall notice covers boxes with a date from June 2018 to June 2019, federal health officials now say consumers shouldn't bother checking dates or sizes and just avoid all boxes.
Symptoms of salmonella infection include diarrhea, fever and abdominal cramps and typically present 12 to 72 hours after exposure to the bacteria.More news: What President Trump said about May, Brexit, and 'England'
