CDC Declares Raw Farm E. Coli Outbreak Over

The U.S. Centers for Disease Control and Prevention (CDC) announced that an E. coli outbreak linked to Raw Farm raw cheddar cheese is over as of April 30.

The CDC and U.S. Food and Drug Administration (FDA), in collaboration with state and local partners, investigated the multistate outbreak, reporting nine illnesses and three hospitalizations in three states: California, Florida and Texas.

More than half of those sickened were children under 5. One person developed hemolytic uremic syndrome (HUS), a serious condition that can cause kidney failure. No deaths have been reported.  

As part of the investigation, FDA and state partners completed onsite inspections and sample collections at Raw Farm’s farm and processing facilities in Fresno, Calif. FDA collected and analyzed 19 samples of Raw Farm-brand raw cheddar cheese products. One sample 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 epidemiologic information 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 agency said.

The raw cheddar cheese that tested positive for E. coli was not shipped to stores and is not available for sale, said FDA.

FDA’s outbreak investigation has ended. This advisory will be updated if additional information becomes available.
