The takeaway

Sierra Nevada Cheese Company has recalled all Graziers raw milk cheddar, jalapeño jack, and Monterey jack after CDC and FDA investigators linked it to a nine-state E. coli O26 outbreak that has sickened 13 people, hospitalized eight, and caused three cases of hemolytic uremic syndrome, mostly in young children. Consumers should discard the cheese or return it for a refund.

Sierra Nevada Cheese Company has voluntarily recalled all of its Graziers raw milk cheese after the CDC and FDA linked the product to an E. coli O26:H11 outbreak spanning nine states. As of the latest federal update, 13 people have gotten sick, eight have been hospitalized, and three have developed hemolytic uremic syndrome (HUS), a serious kidney complication — with more than half of the patients children age 5 or younger.

What's being recalled

The recall covers Sierra Nevada Graziers raw milk cheese sold in medium cheddar, sharp cheddar, jalapeño jack, and Monterey jack varieties, packaged in 8-ounce and 16-ounce retail sizes as well as 5-pound wholesale loaves. The FDA says all lots currently in the market are included.

  • Illnesses reported in California, Colorado, Georgia, Kentucky, Michigan, Nevada, Oregon, Tennessee, and Utah
  • 13 confirmed illnesses, 8 hospitalizations, 3 cases of HUS, 0 deaths as of the latest update
  • FDA contacted the company on September 24; the agency issued a public update September 25

Why raw milk cheese carries extra risk

Unlike most commercial cheese, raw milk products skip pasteurization, the heat process that kills bacteria and viruses in milk before it's made into cheese. The FDA noted that all nine people interviewed so far in the investigation reported eating Sierra Nevada Graziers cheese before getting sick, and cautioned that "raw milk products are not pasteurized — a process that kills bacteria and viruses."

What to do if you bought this cheese

Do not eat it, even if some has already been consumed without symptoms. Throw it away or return it to the store where you bought it for a refund, and wash any surfaces, containers, or utensils that touched it with hot, soapy water. Anyone who developed diarrhea, fever, or stomach cramps after eating the cheese should contact a healthcare provider.

Where the investigation stands

The CDC and FDA say the investigation is ongoing and the true number of illnesses is likely higher than confirmed lab-tested cases, since many people recover without being tested. Sierra Nevada Cheese Company has not publicly detailed the source of the contamination.
