Multistate E. coli Outbreak Likely Caused by Raw Cheese, but Manufacturer Refuses to Recall
Raw (unpasteurized) cheese products have been implicated as the likely vehicle of illness in a multistate outbreak of Escherichia coli O157:H7 infections affecting mostly young children—but the producing firm has so far refused to issue a voluntary recall.
Outbreak Case Details
The U.S. Centers for Disease Control and Prevention (CDC) has reported seven confirmed infections in California (five cases), Florida (one), and Texas (one), including two hospitalizations. Most cases (four) involve patients who are three years of age or younger. Known illness onset dates range from September 1, 2025 to February 13, 2026.
Whole genome sequencing (WGS) analysis determined the genetic relatedness of clinical E. coli isolates.
Epidemiologic Evidence Points to RAW FARM-Brand Raw Cheddar Cheese
State and local public health officials have interviewed three patients about food exposures of interest in this outbreak, all of whom reported eating RAW FARM-brand raw cheddar cheese. State and local officials are working to gather additional data for the four other illnesses, including two 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 the outbreak.
FDA has recommended that RAW FARM LLC voluntarily remove its raw cheese products from the market, and the firm has declined.
Confirmatory Product Testing Ongoing
To FDA’s awareness, no RAW FARM-brand cheddar cheese products from the outbreak period have yet tested positive for E. coli. As part of the investigation, state partners have begun collecting product samples for testing and analysis, but results are not yet available.
