The Food and Drug Administration has expanded its investigation into an outbreak of infections caused by Salmonella Infantis that has been linked to flour.

As of the most recent update, on March 30, from the Centers for Disease Control and Prevention, the outbreak has sickened at least a dozen people across 11 states. Three of the patients have required hospitalization. No deaths have been reported.

Although a specific brand of flour has not been revealed by federal officials, the FDA reports that it has begun onsite inspection of an unnamed location and sample collection.

Illnesses started on dates ranging from Dec. 6, 2022, to Feb. 13, 2023, but there are likely more sick people who have not yet been confirmed because of the time it takes for testing and reporting.

The sick people live from coast to coast in Oregon, California, Nebraska, Minnesota, Iowa, Missouri, Illinois, Tennessee, Ohio, Virginia and New York. Whole genome sequencing from lab samples from the patients shows a common cause for their infections. 

The CDC continues to remind people to exercise caution when cooking with flour. Raw dough and batter should not be eaten and children should not be allowed to play with raw flour. Utensils used when cooking with raw flour and surfaces that come into contact with it should be thoroughly cleaned and sanitized. Flour is a raw agricultural product and can be easily contaminated when grain is processed.
