Update March 30, 2026: Since the last FDA announcement 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. 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), a serious condition that can cause kidney failure. 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. Of the seven (7) people interviewed who knew a brand, seven (7) (100%) reported RAW FARM-brand dairy products. 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.
Whole genome sequencing (WGS) analysis of E. coli isolates from ill people shows that they are all closely related genetically to each other. This means that people in this outbreak are likely to share a common source of infection.
FDA has initiated an onsite inspection at RAW FARM, LLC in coordination with state partners. To date, 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.
Original News Story March 19, 2026: The FDA and CDC, in collaboration with state and local partners, are investigating a multistate outbreak of E. coli O157:H7 infections as reported on FDA’s website
As of March 14, 2026, a total of 7 confirmed infections have been reported from three states, including CA (5), FL (1), and TX (1). Known illness onset dates range from September 1, 2025 to February 13, 2026. Whole genome sequencing analysis of E. coli isolates from ill people shows that they are all closely related genetically to each other. This means that people in this outbreak are likely to share a common source of infection. Additionally, 4 of 7 cases are 3 years old or younger. Two patients have been hospitalized. No deaths or HUS cases have been reported.
State and local public health officials have interviewed 3 ill people about food exposures of interest in this outbreak. All 3 people (100%) reported eating RAW FARM- brand raw cheddar cheese. State and local officials are working to gather additional data for the 4 other illnesses, including 2 illnesses that occurred in 2025. Epidemiologic evidence indicates that RAW FARM-brand raw cheddar cheese products made by RAW FARM, LLC are the likely source of this outbreak.
FDA has recommended that RAW FARM, LLC voluntarily remove their raw cheese products from the market, and the firm has declined.
On the company’s website, RAW FARM issued their official statement “We 100% disagree with FDA’s false possible link and extreme allegations.” Aaron McAFee, President of RAW FARM is filmed in a 2:13 minute YouTube video explaining their position.
FDA states, the investigation is ongoing to determine the source of contamination and whether additional products are linked to illnesses. To date, to FDA’s awareness, no RAW FARM-brand cheddar cheese products from this time period have tested positive for E. coli. As part of this investigation, state partners initiated collection of product samples for testing and analysis, but results are not yet available.
