Multistate E. Coli O26:H11 Outbreak Linked to Raw Milk Cheese: What Consumers Must Know

Federal health authorities—including the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC)—are actively investigating a multistate outbreak of Shiga toxin-producing E. coli O26:H11 infections tied directly to raw milk cheese products.

As public health officials trace contaminated batches and retailers pull products from shelves, understanding the risks of unpasteurized dairy and knowing your consumer rights is vital for household safety.

Outbreak Snapshot and Details

According to federal surveillance data, the outbreak has resulted in confirmed illnesses across multiple states, with a disproportionate impact on vulnerable populations:

• Case Count and Spread: Confirmed cases have been reported across nine states, including California, Colorado, Georgia, Kentucky, Michigan, Nevada, Oregon, Tennessee, and Utah.
• High Hospitalization Rates: A significant majority of affected individuals required hospital care due to severe gastrointestinal distress.
• Severe Kidney Complications: Multiple patients developed Hemolytic Uremic Syndrome (HUS), a dangerous and potentially fatal kidney complication associated with Shiga toxin-producing strains.
• Impact on Children: More than half of the individuals sickened in this outbreak are children aged five years or younger, who face the highest risk of long-term health damage.

The Recalled Product: Sierra Nevada Graziers Cheese

Following traceback interviews where 100% of interviewed patients reported consuming raw milk cheese products, the FDA notified the manufacturer. Sierra Nevada Cheese Company, based in Willows, California, initiated a voluntary recall covering all varieties of its Graziers raw milk cheese products.

• Recalled Varieties: Medium cheddar, sharp cheddar, jalapeño jack, and Monterey jack raw milk cheeses.
• Packaging: Distributed in 8-ounce and 16-ounce retail packages, as well as 5-pound loaves intended for food service and wholesale operations.
• Distribution: Shipped nationwide through retail stores, specialty distributors, and direct-to-consumer channels.

Why Raw Milk Products Carry Higher Risks

Unlike standard commercial cheeses made from pasteurized milk—where a heating process kills harmful bacteria—raw milk cheese is produced using unpasteurized milk to preserve traditional flavors and textures.

Because raw milk skips this thermal kill-step, pathogens like E. coli can survive for weeks or months inside aged or soft cheeses. Furthermore, because cheese has a long shelf life, consumers may still have recalled products sitting in their home refrigerators or freezers.

What Consumers and Retailers Should Do

Health officials advise consumers who purchased any Sierra Nevada Graziers raw milk cheese to check their refrigerators immediately. Do not consume or serve the product; either return it to the store for a full refund or discard it securely. Retailers and restaurants must immediately pull all remaining stock to prevent further exposure.
