BATTLE CREEK, MICH. — The Kellogg Co. on June 14 initiated a voluntary recall of 1.1 million boxes of 15.3-oz and 23-oz packages of its Honey Smacks cereal, citing the “potential presence of Salmonella.” 

The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention are investigating a multi-state outbreak of Salmonella Mbandaka infections that indicate Kellogg's Honey Smacks cereal as the likely source, the C.D.C. said. Seventy-three people infected with the outbreak strain have been reported from 31 states, and 24 have been hospitalized. 

Kellogg said it has launched an investigation with the third-party manufacturer who produces Honey Smacks.

The affected products include 23-oz boxes distributed in the United States with a “Best if Used By Date” of June 14, 2018, through June 14, 2019, as well as 15.3-oz boxes distributed in Costa Rica, Guatemala, Mexico, the Caribbean, Guam, Tahiti and Saipan with a “Best if Used By Date” of June 14, 2018, through June 14, 2019.
