According to the US Centers for Disease Control and Prevention, more than 100 people have gotten sick from recalled Kellogg’s Honey Smacks cereal. The multistate outbreak of salmonella illness linked to the cereal has now reached 33 states. Florida and Colorado are the latest states to report illnesses as part of the outbreak.

People have reportedly been getting sick from the cereal since March, although the outbreak was not announced until June. By June 14th, the Kellogg Company (NYSE: K) had announced a recall of the product in most states, as well as internationally. An estimated 1.3 million cases of Honey Smacks were taken off of shelves.

Both the 15.3-ounce and 23-ounce boxes of the cereal were recalled. The 15.3-ounce box has the UPC code“38000 39103″ while the 23-ounce box is “38000 14810.” They all have a “best if used” date of June 14th, 2018 through June 14th, 2019.

Despite the massive recall, the US Food and Drug Administration found that some grocery stores and other retailers were still selling the cereal from the contaminated batch. In a statement, the agency said, “The FDA has become aware that recalled Kellogg’s Honey Smacks cereal are still being offered for sale. All Honey Smacks cereal was recalled in June 2018. Retailers cannot legally offer the cereal for sale and consumers should not purchase Kellogg’s Honey Smacks cereal.”

The FDA said it would follow up with retailers to make sure the cereal is cleared from stores. The FDA is advising the public to report any sales of the cereal to the FDA Consumer Complaint Coordinator in their area. Any consumers with the recalled product in their possession should throw the cereal away or return it to the retailer for a refund.

The first cases of illness in this outbreak began with symptoms on March 3. Symptoms typically present 12 to 72 hours after exposure and include diarrhea, fever and abdominal cramps. Symptoms last about four to seven days, and most people improve without treatment, which is generally a course of antibiotics. No deaths have been reported in this outbreak.
