Sierra Nevada raw milk cheese tied to 13 E. coli cases and eight hospital stays, FDA says

A voluntary recall of Sierra Nevada Graziers raw milk cheeses follows a multistate E. coli outbreak that sickened 13 people and put eight in the hospital, federal health officials say.

Fox Business reported that Sierra Nevada Cheese Company, LCC pulled its Sierra Nevada Graziers grass-fed raw milk cheeses after federal investigators linked the products to a stretch of E. coli O26:H11 infections.

Thirteen people fell ill. Eight needed hospital care. Public health officials have interviewed nine of those patients, and every one of them said they ate the cheese within the week before getting sick. The last known symptom onset was Aug. 26.

Cases have turned up in California, Nevada, Oregon, Utah, Colorado, Michigan, Kentucky, Tennessee, and Georgia. The cheeses sold in retail 8-ounce and 16-ounce packages. The source of the contamination is still unknown, and the FDA says its probe continues.

Shoppers who bought the brand should treat the warning as urgent. The agency is clear: do not eat the recalled cheese, and retailers should not sell or serve it. That same pattern of federal action has shown up in other recent food alerts, including a raw milk cheese recall tied to E. coli cases covered earlier.

Federal agencies press the investigation while product stays on shelves at home

The FDA framed the work in plain terms.

The agency stated:

"The FDA and CDC, in collaboration with state and local partners, are investigating a multistate outbreak of E. coli O26:H11 infections linked to Sierra Nevada Graziers grass-fed raw milk cheese,"

It added a second line that leaves no comfort for anyone still holding the product:

"FDA’s investigation is ongoing."

That ongoing status matters. Investigators have not publicly pinned down whether the problem started at a farm, a processing step, a supplier, or somewhere else in the chain. Until they do, the practical burden falls on families checking cold storage. Similar pressure has hit grocery aisles before, as when Wakefern recalled applesauce after elevated toxin findings.

The company issued the recall voluntarily and is working with the FDA. Voluntary action is better than silence. It is not the same as a finished answer on how dangerous bacteria reached retail cheese in the first place.

Long shelf life keeps the risk in home kitchens

Federal guidance is blunt because this product does not spoil on a short clock.

The FDA said:

"Do not eat, sell, or serve recalled Sierra Nevada Graziers grass-fed raw milk cheeses,"

And it spelled out the home-check rule:

"This product has a long shelf life. Check your refrigerators and freezers for the recalled raw milk cheeses and throw them away. If you refrigerated or froze cheese without the original packaging and can’t tell if it’s part of the recall, throw it away."

If the original package is gone, the instruction is still to discard it. Surfaces and containers that touched the cheese should be cleaned. E. coli symptoms can start as late as nine days after someone eats contaminated food, which means a meal from last week can still turn into a hospital visit this week.

Food recalls keep stacking up across categories. The FDA has also moved hard on produce and spice contamination, including when it gave NatureBest jalapeño products its highest risk rating and later hit Taylor Farms jalapeño items with a top-tier recall grade across dozens of states. Those cases are separate. The pattern is familiar: contamination found after people already got hurt.

Nine states, eight hospital beds, and no identified contamination source

The geography alone should focus attention. Illnesses span the West, the Mountain states, the Midwest, and the South. Three people were sickened in California and Nevada, with additional cases reported one each in Oregon, Utah, Colorado, Michigan, Kentucky, Tennessee, and Georgia, according to the case tally shared with the public. The full count stands at 13 sick and eight hospitalized. No deaths are listed in the available federal summary.

Patient interviews are doing the early linking work. Nine people talked to public health officials. All nine reported eating the Sierra Nevada Graziers cheese in the prior week. That kind of consistent food history is why the brand is at the center of the outbreak notice even while lab work on the contamination source continues. Lead and other contaminant scares have followed a similar public path, including when Lior ground cinnamon was recalled across six states over elevated lead levels.

For now, the operational order is simple. Do not eat it. Do not sell it. Do not serve it. Throw out what you cannot identify. Sanitize what it touched. And wait for the FDA and CDC to finish explaining how E. coli O26:H11 got into grass-fed raw milk cheese that reached kitchen tables in nine states.

When a food product lands people in the hospital, families deserve a finished investigation and a company culture that treats contamination as a hard stop, not a paperwork drill.
