The CDC warned customers, saying "Do not eat this cereal".

Kellogg's Honey Smacks cereal has now been linked to at least 100 cases of salmonella infection across the US since March.
The FDA said on Thursday it would follow up with retailers to prevent the sale of the product.
The number of people with salmonella linked to Kellogg's Honey Smacks cereal has grown to 100 across the United States, prompting the CDC to issue a blunt warning via tweet: "Do not eat this cereal". The recall was issued June 14. At that time, 73 people in 31 states had confirmed cases of salmonella poisoning.More news: 20 million watched England World Cup victory against Sweden
Two people in Kentucky have become ill with this strain of Salmonella.
But efforts to recall the product were not successful.
The number of cases in Louisiana remains the same as it was in June: Two people have gotten sick.
Kellogg Company, which did not respond to an immediate request for comment, launched an investigation into a third-party manufacturer who produces the cereal in mid-June after the infections were reported, according to the FDA. But the cereal is still being sold in some stores.
If you have a box of Honey Smacks that falls within those dates you should most definitely not eat it, and promptly contact Kellogg's for a full refund. "Thoroughly wash the container with warm, soapy water before using it again, to remove harmful germs that could contaminate other food". However, some people develop symptoms so severe that they need to be hospitalized. Most infections usually last four to seven days and most people recover without treatment.
