A significant outbreak of E. coli O157:H7 infections has emerged, connected to RAW FARM-brand raw cheddar cheese. As of March 26, 2026, the Centers for Disease Control and Prevention (CDC) and the US Food and Drug Administration (FDA) have confirmed nine cases across three states, primarily affecting children under the age of five .

Epidemiological investigations indicate that all individuals reported consuming RAW FARM-brand cheese or other raw dairy products in the week prior to their illness. Of the nine reported cases, three individuals have been hospitalized, and one developed hemolytic uremic syndrome (HUS), a severe condition that can result in kidney failure. Fortunately, no fatalities have been recorded thus far .

The outbreak has primarily impacted California, with five confirmed cases, while Florida and Texas have reported fewer cases. Public health officials note that the actual number of infections may be higher than reported due to underdiagnosis, as many affected individuals do not seek medical care or undergo testing for E. coli infections .

Health Risks and Symptoms

Health officials are particularly concerned about the potential for severe illness among vulnerable populations. Symptoms of E. coli infection include severe stomach cramps, diarrhea (which may be bloody), fever, nausea, and vomiting. These symptoms typically manifest three to four days after exposure to the bacteria, with most individuals recovering within a week. However, some cases can lead to serious complications, especially in young children, older adults, and those with weakened immune systems .

Recommendations for Consumers

In light of the ongoing investigation, the FDA and CDC have issued clear recommendations. Consumers are advised not to eat or serve RAW FARM-brand raw cheddar cheese and to dispose of any such products immediately. Furthermore, it is crucial to clean and sanitize any surfaces or utensils that may have come into contact with the cheese to prevent cross-contamination .

Retailers and food service providers are also urged to refrain from selling or serving RAW FARM-brand products until further notice. The FDA has recommended a voluntary recall of these products; however, RAW FARM, LLC has not complied with this recommendation as of the latest updates, raising concerns about public safety .

Ongoing Investigation

The investigation remains active, with public health officials conducting interviews and collecting data to trace the outbreak's source. Whole genome sequencing has confirmed that the E. coli strains isolated from ill individuals are genetically related, suggesting a common source of contamination. The FDA has initiated inspections at RAW FARM facilities, although no positive tests for E. coli have been reported in products manufactured during the outbreak period .

Public health authorities emphasize the importance of consumer awareness regarding food safety, especially concerning raw dairy products. They recommend choosing pasteurized dairy options to mitigate the risk of infection from harmful bacteria such as E. coli O157:H7 .

For the latest updates on this outbreak, the CDC and FDA have provided resources for consumers and health care providers. Individuals experiencing symptoms consistent with E. coli infection after consuming RAW FARM-brand products are advised to consult their health care provider immediately .

Public health officials continue to monitor and investigate this outbreak, working closely with state and federal partners to prevent further illnesses. Consumers are encouraged to stay informed and cautious as the situation develops.
