The CDC tweeted: "Do not eat this cereal".
At least 30 people have been hospitalized due to the outbreak, the CDC said. The source of the outbreak remains under investigation. In these patients, the Salmonellainfection may spread from the intestines to the blood stream and then to other body sites and can cause death unless the person is treated promptly with antibiotics.
Regardless of the expiration date, the CDC says you should throw away the cereal or return it to a retailer for a refund.
The agency has said that it has found salmonella stains in unopened and leftover samples of Honey Smacks. The outbreak began on June 8, prompting Caito Foods, LLC to recall precut watermelon, honeydew melon, cantaloupe and fruit medley products produced at the Caito Foods facility in Indianapolis. Though the recall covers cereal with a best-by date of June 14, 2018, through June 14, 2019, the agency is recommending people avoid the cereal altogether.More news: Theresa May urges Tory backbenchers to keep Jeremy Corbyn out of power

Florida and Colorado are the latest states to report illnesses as part of the outbreak, bringing the total number of states affected to 33.
Of those victims who were interviewed about what they ate, the most cited cereal was Honey Smacks.
The illness usually lasts about four to seven days. But the cereal is still being sold in some stores.
Kellogg in June recalled an estimated 1.3 million cases of its Honey Smacks cereal from more than 30 US states due to the potential for Salmonella contamination. About 1.2 percent of people infected get severe diarrhea that leads to hospitalization. Symptoms develop between 12 and 72 hours after infection and feature a fever, cramps, or diarrhea.
