Current Update
April 30, 2026
The FDA and CDC, in collaboration with state and local partners, investigated a multistate outbreak of E. coli O157:H7 infections linked to RAW FARM-brand raw dairy products.
As of April 30, 2026, CDC announced that the outbreak is over. CDC reports a total of nine illnesses in three states. Illnesses started on dates ranging from September 1, 2025, to February 20, 2026. Three people were hospitalized and one person developed hemolytic uremic syndrome (HUS), a serious condition that can cause kidney failure. No deaths have been reported.
As part of this investigation, FDA, in coordination with state partners, completed onsite inspections and sample collections at RAW FARM, LLC farm and processing facilities. FDA collected and analyzed 19 samples of RAW FARM-brand raw cheddar cheese products. One sample of RAW FARM-brand cheddar cheese tested positive for E. coli O157:H7, and FDA performed further testing and analysis through whole genome sequencing (WGS), or DNA fingerprinting. According to CDC, the strain of E. coli found in the cheese was related to sick people’s isolates from a different 2025 outbreak, that was not ongoing. CDC and states followed up to determine if there was any epidemiologic information that showed whether people in the 2025 outbreak consumed any RAW FARM-brand products. None of the ill people in the older 2025 outbreak reported consuming any RAW FARM-brand raw dairy products.
The raw cheddar cheese that tested positive for E. coli was not shipped to stores and is not available for sale. There are no additional FDA or state samples pending analysis at this time.
FDA’s outbreak investigation has ended; this advisory will be updated if additional information becomes available.

Previous Update
April 16, 2026
The FDA and CDC, in collaboration with state and local partners, continue to investigate a multistate outbreak of E. coli O157:H7 infections linked to RAW FARM-brand raw dairy products.
As part of this investigation, FDA, in coordination with state partners, has completed onsite inspections and sample collections at RAW FARM, LLC retail and processing facilities. FDA has collected and analyzed 19 samples of RAW FARM-brand raw cheddar cheese products. One sample of RAW FARM-brand Cheddar Cheese tested positive for E. coli O157:H7.
FDA conducted further testing and analysis through whole genome sequencing (WGS), or DNA fingerprinting. This showed that the strain of E. coli found in the cheese is a different strain than the E. coli in the current outbreak. Instead, this strain matches illnesses from a different 2025 outbreak investigated by CDC. The 2025 outbreak is not ongoing, but CDC and states are following up to determine if there is any epidemiologic information from that 2025 outbreak that shows if those sick individuals consumed any RAW FARM-brand products.
The raw cheddar cheese that tested positive for E. coli was not shipped to stores and is not available for sale. Sample testing and analyses by state partners are ongoing. Any additional positive test results will be reported if they become available.
On April 2, 2026, RAW FARM, LLC initiated a recall of certain RAW FARM-brand cheeses. On April 7, 2026, RAW FARM, LLC updated the language and product names on its recall announcement for certain RAW FARM-brand cheeses.
