Meanwhile, The FDA and Centers for Disease Control and Prevention are continuing to investigate a multistate outbreak of E. coli O26:H11 infections linked to Sierra Nevada Graziers grass-fed raw milk cheese. The outbreak has sickened 13 patients across eight states from coast to coast. More than half of the patients are children younger than 5. Eight of the patients have required hospitalization and three have developed hemolytic uremic syndrome, which can cause kidney failure, brain damage and sometimes death.
State and local public health officials are interviewing ill people or their caregivers about the foods they ate in the week before they got sick. Of nine people interviewed, all nine in this outbreak reported consuming Sierra Nevada Graziers grass-fed raw milk cheese.
The company has initiated a recall for all of its raw milk cheese. The recalled Sierra Nevada Graziers grass-fed raw milk cheeses were distributed nationwide. They are sold in medium cheddar, sharp cheddar, jalapeño jack, and Monterey jack varieties in 8-ounce or 16-ounce packages and available to food service customers or wholesalers in 5-pound loaves.
This is not the company’s first problem with raw milk. In August 2025, California’s State Veterinarian ordered a statewide recall and quarantine of Sierra Nevada’s Bella Capra raw goat milk cheddar after California Department of Food and Agriculture testing found Listeria monocytogenes in the cheese.
