WASHINGTON — The Food and Drug Administration on July 12 said Kellogg’s Honey Smacks cereal was still being offered for sale a month after a recall of the product by Kellogg Co., Battle Creek, Mich.

The episode dates back to May 17 when the F.D.A. learned of a cluster of Salmonella illnesses in multiple states. On June 14, Kellogg voluntarily recalled Honey Smacks after an investigation of the third-party manufacturer that produced the sweetened, puffed wheat cereal.

In its update, the F.D.A. said 100 people have been sickened with the Salmonella Mbandaka strain in 33 states. No deaths have been reported, but 30 individuals have been hospitalized. The F.D.A. is advising consumers not to eat Honey Smacks, regardless of size or “best if used by“ dates.
