On March 26, 2026, the FDA and CDC, in collaboration with state and local partners, reported that they were investigating a multistate outbreak of E. coli O157:H7 infections linked to RAW FARM-brand raw dairy products. FDA’s investigation is ongoing. Since the last update on March 15, 2026, two (2) additional illnesses have been reported. A total of nine (9) people infected with the outbreak strain of E. coli have been reported from three (3) states (CA, FL, TX). Illnesses started on dates ranging from September 1, 2025, to February 20, 2026. Three (3) people have been hospitalized , and one (1) person developed hemolytic uremic syndrome (HUS). No deaths have been reported. Over half of the illnesses are in children under five (5) years old. State and local public health officials are interviewing people or their caregivers about the foods they ate in the week before they got sick. Of the eight (8) people interviewed, all eight (8) (100%) in this outbreak reported consuming or being served raw dairy products. Of the eight (8) people interviewed, seven (7) had brand information available. One (1) person drank raw milk but didn’t know the brand.

In 2026, five (5) people reported consuming or being served RAW FARM-brand raw cheddar cheese. In 2025, two (2) sick people reported consuming RAW FARM-brand raw milk. Affected RAW FARM-brand raw milk from 2025 should no longer be for sale. (WGS) analysis of E. coli isolates from ill people shows that they are all closely related genetically. This means that people in this outbreak are likely to share a common source of infection. The FDA has initiated an on-site inspection at RAW FARM, LLC in coordination with state partners. To date, the FDA is not aware of any positive E. coli tests in RAW FARM-brand raw cheddar cheese products from this time period. FDA will update this advisory should additional information become available. https://www.fda.gov/food/outbreaks-foodborne-illness/outbreak-investigation-e-coli-o157h7-raw-cheddar-cheese-march-2026?utm_medium=email&utm_source=govdelivery
