MMWR on Multistate Outbreak of E. coli O26 Infections Linked to Raw Flour
Most consumers do not recognize that raw, or uncooked, flour, is considered a health risk as this item is a raw agricultural product that has not undergone a kill step to eliminate pathogens. In the April 23, 2021 issue of the CDC’s Morbidity and Mortality Weekly Report (MMWR), a study is presented that looked at the 2019 multistate outbreak of E. coli O26 linked to raw flour.
On February 20, 2019, PulseNet identified six Shiga toxin-producing E. coli O26:H11 infections with the same DNA fingerprint. This pattern matched infections from a July 2018 outbreak that was associated with ground beef. The Centers for Disease Control and Prevention (CDC) launched an investigation to identify the outbreak source.
