Is your Sierra Nevada raw milk cheese part of the E. coli recall?

Sierra Nevada Cheese Company started the voluntary recall September 24 after the FDA contacted the firm. It covers four Graziers grass-fed raw milk varieties: medium cheddar, sharp cheddar, jalapeno jack, and Monterey jack. Every size is included, from 8-ounce retail packs to 16-ounce packs to 5-pound food service loaves, sold nationwide through stores, restaurants, and online. No lot codes or best-by dates narrow it. If you have any of those four varieties in any size, it's included.

Thirteen people across nine states are sick so far. Eight have been hospitalized. Three children have developed hemolytic uremic syndrome, a form of acute kidney failure. More than half the reported cases are in children age 5 or younger. The pathogen is a Shiga toxin-producing E. coli, strain O26:H11, and the HUS cases suggest this one carries Shiga toxin 2, the subtype that does the most damage.

What to do with any package you find

Pull it from the fridge, throw it out or return it to the store, and wash the shelf, the drawer, and anything else it touched with hot soapy water. Run reusable containers through the dishwasher. The cheese moved through retail, food service, and online channels nationwide, so this isn't a regional check. The four recalled varieties are:

• Graziers grass-fed raw milk medium cheddar (8 oz, 16 oz, and 5 lb)
• Graziers grass-fed raw milk sharp cheddar (8 oz, 16 oz, and 5 lb)
• Graziers grass-fed raw milk jalapeno jack (8 oz, 16 oz, and 5 lb)
• Graziers grass-fed raw milk Monterey jack (8 oz, 16 oz, and 5 lb)

Why the sick are almost all children

The age skew is biology, not bad luck. In pediatric surveillance and a large multinational cohort, roughly 15 to 20 percent of young children infected with a Shiga toxin 2-producing E. coli go on to HUS. About half of those children need dialysis. A smaller share develop neurologic complications like seizures. Adults are hit less often and less hard. Young kids carry little pre-existing immunity to Shiga toxins, their kidney microvasculature is more sensitive to the toxin, and it doesn't take much bacteria to start the process. STEC has one of the lowest infectious doses of any foodborne pathogen, fewer than a hundred organisms in some outbreaks, and raw milk cheese delivers those bacteria straight into the gut without the heat step that would otherwise kill them. A bite on a cracker is enough.

What to watch for, and for how long

Symptoms usually start three to four days after eating contaminated food and can appear up to nine days later, per FDA guidance for this outbreak. Anyone in your household who ate the cheese in the last week and a half is still inside the window, even if they feel fine now. The signature course is severe abdominal cramping and watery diarrhea that turns bloody in more than half of cases, often with vomiting. In a young child, the shift from watery to bloody stools is the moment it stops being an ordinary stomach bug.

Get to care right away for any of these: bloody stools, fever above 102°F, diarrhea lasting more than two days, repeated vomiting, or dehydration signs like few wet diapers, dry mouth, sunken eyes, or unusual sleepiness. Fever is only present in about a third to half of infected children, so a normal temperature doesn't rule STEC out. And HUS itself typically shows up about a week after the diarrhea starts, sometimes up to two or three weeks later. Keep watching even after the stomach symptoms ease.

The treatment trap

This is the part most parents, and many first-visit clinicians, don't know. For suspected or confirmed STEC, there's no drug that kills the bacteria and helps. Care is supportive: early intravenous fluids to protect the kidneys, and lab monitoring for the platelet, hematocrit, and creatinine changes that mark HUS coming on.

Two common instincts make things worse. Antibiotics raise HUS risk in the higher-quality observational studies, with beta-lactams like amoxicillin roughly doubling the odds, because damaging the bacteria triggers a burst of Shiga toxin release into the gut. The evidence is observational and effect sizes vary by drug class, but no antibiotic has been shown to help, and beta-lactams in particular should be avoided. Anti-diarrheal medicines like loperamide also raise HUS risk, because slowing gut transit keeps toxin in contact with the lining longer.

Both are things a worried parent might reach for at home. Both are things a busy urgent-care visit might prescribe empirically for bloody diarrhea. The single most useful thing you can do is get to a clinician early, name the recalled raw milk cheese, and hold off on antibiotics and anti-diarrheal medicines until STEC has been ruled out or confirmed.

Small outbreak, large stakes

Thirteen cases in nine states looks small on paper. It isn't. Raw milk cheese can carry Shiga toxin-producing E. coli at doses low enough to sicken a toddler from a single bite, and it delivers that dose to the population least equipped to survive it. Each of the three children with HUS is somebody's child. For the next nine days, the two decisions that matter are yours: identify and discard the cheese, and recognize the shift from stomach bug to something worse fast enough that the first clinician gets it right.
