They're a staple in many families' pantries and kid's lunchboxes and now Ritz Bits crackers are being recalled over possible Salmonella contamination. Mondelēz Global, the company that makes the popular crackers, is recalling 16 varieties of Ritz Cracker Sandwiches and Ritz Bits Product in the U.S. Five cheese and pizza flavors are being recalled in Canada.

The recall comes after the whey powder used in the crackers was recalled by its supplier due to the the potential presence of Salmonella. The recall impacts the sandwich-style Ritz varieties, including the individually packaged cups and bags of cheese flavored Ritz Bits.

The cracker manufacturer says there have been no cases of illness linked to the recalled Ritz varieties yet, but advises consumers to throw away any of the packages impacted by the recall.

"Consumers who have these products should not eat them, and should discard any products they may have. Consumers can contact the company at 1-844-366 -1171, 24 hours a day to get more information about the recall, and Consumer Relations specialists are available Monday-Friday, 9am to 6pm EST.," Mondelēz Global states in a media release.

According to the CDC , Salmonella causes about 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths in the United States yearly.

Most people recover without treatment from an episode of diarrhea, fever and cramps that lasts about a week, but some people do need to be hospitalized and of course small children are among those most at risk , with kids under five having higher rates of Salmonella infection than any other age group.
