E. coli O157:H7 outbreak linked to raw cheddar cheese from California producer

The FDA and CDC are investigating an outbreak of seven cases of E. coli O157:H7 illnesses in three US states.

Outbreak cases have been reported in California (5), Florida (1), and Texas (1).

Four of the seven victims are three years old or younger, and two people have been hospitalized.

No deaths have been reported, and none of the victims have developed hemolytic uremic syndrome (HUS) as of March 14, 2026.

The first two illnesses associated with this outbreak were recorded in September 2025, and the other five in January and February of 2026.

The CDC warns that the number of outbreak illnesses is likely much higher than reported, as many individuals recover without seeking medical care and are not tested.

Three of the victims have been interviewed so far, and all three reported eating RAW FARM-brand cheddar cheese made from raw (unpasteurized) milk.

Testing of product samples is in progress, but results are not yet available.

The producer, RAW FARM, LLC (previously known as Organic Pastures), has declined the FDA’s recommendation that their raw cheese products be removed from the market.

This is the second time in two years that RAW FARM-brand raw cheddar cheese has been linked epidemiologically to an outbreak of E. coli O157:H7 illnesses.

On March 26, 2024, the FDA and CDC reported an outbreak of 11 illnesses, including five hospitalizations. Outbreak were reported in California (4), Colorado (3), New Jersey (1), Texas (1), and Utah (2). Two of the outbreak victims developed HUS. There were no deaths.

Seven of the ten victims interviewed as part of the outbreak investigation specifically reported eating RAW FARM brand raw cheddar cheese prior to becoming ill.

The company initially recalled their raw cheddar cheese, but subsequently withdrew their recall after testing of cheese samples failed to find E. coli.

From October 2023 through May 2024, raw milk and cream produced by RAW FARM, LLC was implicated in a Salmonella Typhimurium outbreak that affected 171 individuals in the state of California primarily in the southern counties of the state. Children were affected disproportionately.

In addition to epidemiological evidence pointing to RAW FARM-brand raw milk as the source of the illnesses, the outbreak strain was recovered from three samples of raw milk and one sample of cheese made from the contaminated raw milk.

In October 2023, the company recalled all fluid raw whole milk and raw heavy cream (Best by dates from 10/11/2023 to 11/6/2023.

Even before this major outbreak, the company’s operations had come under scrutiny by the FDA. The federal agency conducted an inspection of Organic Pasture’s (as it was then known) production facility in February 2021, and issued a Form 483 listing several significant infractions, including inadequate sanitary handling procedures, flaws in the company’s hazard analysis for Salmonella and for Listeria monocytogenes, and inadequate record keeping relating to sanitation operations.

The FDA classified the result of the inspection as Official Action Indicated, a failing grade.

Although raw milk and other dairy products made with raw (unpasteurized) milk are not permitted to be shipped for retail sale across state lines, they are legal for retail sale within a number of states, including California.

According to the FDA, since 1987 and up to March 2024, there have been 143 recorded outbreaks of illnesses in the United States associated with consumption of raw milk and raw dairy products. These include outbreaks of Listeria monocytogenes, Campylobacter, Salmonella, and shiga toxin-producing E. coli (such as E. coli O157:H7).

If you consumed a RAW FARM, LLC cheese product and you develop symptoms of gastrointestinal upset within the few days following consumption, consider seeking medical treatment, especially if your symptoms include one or more of the following:

  • Diarrhea and a fever higher than 102°F
  • Diarrhea for more than 3 days that is not improving
  • Bloody diarrhea
  • So much vomiting that you cannot keep liquids down
  • Signs of dehydration, such as:
    • Not peeing much
    • Dry mouth and throat
    • Feeling dizzy when standing up

Green moringa powder scores Salmonella hat trick

For the third time in less than three months, green moringa powder has been linked to an outbreak of Salmonella illnesses.

The most recent outbreak, announced by the US Centers for Disease Control and Prevention (CDC) on February 13, 2026, currently consists of seven confirmed cases of Salmonella Newport infections in seven states. Three of the seven victims have been hospitalized. The outbreak strain is described by the CDC as being “extensively drug-resistant.”

The outbreak has been traced to certain lots of Rosabella brand moringa powder capsules, distributed by Ambrosia Brands, LLC. The implicated lots of product have been recalled.

Outbreak cases have been reported by Arizona, Florida, Iowa, Illinois, Indiana, Tennessee, and Washington. The first victim became ill on November 7, 2025; the most recent began to develop symptoms on January 8, 2026. Victims range in age from 61 to 78 years, with a median age of 66. Six of the seven victims are female.

The first Salmonella outbreak linked to moringa powder involved a strain of Salmonella Richmond. That outbreak comprised eleven victims in seven states. Once again, three people were hospitalized.

The outbreak was traced to a single lot of organic moringa leaf powder from Vallon Farmdirect PVT LTD of Johdpur, India. The contaminated powder was a component of Organic Moringa Leaf Powder and Organic Supergreens Powder mix sold by Food to Live, Member’s Mark Super Greens Powdered Supplements, sold at Sam’s Clubs, and Africa Imports Organic Moringa Powder.

Victims of this outbreak were from Florida, Kansas, Michigan, North Carolina, New York, South Carolina, and Virginia. The first illness appeared in May 2025, and the most recent in September 2025. Victims ranged in age from 13 to 65 years, with a median age of 52. Eight of the victims were female.

This was the largest of the three outbreaks, comprising 65 confirmed cases of Salmonella Typhimurium or Salmonella Newport infections and 14 hospitalizations in 28 states. The outbreak was first reported by the CDC on January 14, 2026. The agency issued status updates on January 15th and January 29th. The investigation of this outbreak remains open.

The infections were linked to consumption of Why Not Natural Organic Moringa – Green Superfood and Live it Up Super Greens. Both products were recalled.

Illnesses related to this outbreak started on dates ranging from August 22, 2025 to January 11, 2026. Victims ranged inb age from 3 to 81 years, with a median age of 45. One-third of the outbreak victims are female.

Outbreak cases have been reported by Alabama, California, Connecticut, Delaware, Illinois, Iowa, Kentucky, Maine, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, North Carolina, North Dakota, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, Washington, and Wisconsin.

We’ve been here before. More than 10 years ago, a raw organic powdered shake meal replacement product was linked to a multistate outbreak of Salmonella Virchow infections. That meal replacement product contained organic moringa leaf powder imported from South Africa.

The FDA was able to confirm the presence of the outbreak strain in a sample of organic moringa leaf powder used in the production of RAW Meal Organic Shake and Meal Replacement products, which were available in several flavors. The manufacturer, Garden of Life, LLC, recalled the implicated products.

The outbreak began as a cluster of 6 infections from 5 states. It grew to encompass 35 cases in 24 states. Six people were hospitalized.

Victims in this outbreak ranged in age from less than 1 to 84 years.

In 2016, likely in response to this outbreak, the FDA added moringa powder from K. Paulsen Botanicals, a South African company, to its Import Alert 99-19 (Detention Without Physical Examination of Food Products Due to the Presence of Salmonella).

Billed as a “superfood” or a “Miracle Tree,” the leaves and pods of the moringa tree are rich in nutrients and can be used to treat malnutrition. The tree is native to North India, but can be grown in any subtropical or tropical region with a temperature around 25º-35ºC.

Moringa leaves are rich in mineral such as calcium, iron, and copper, contain multiple vitamins, and several phytochemicals. Moringa pods are high in fiber and protein.

Moringa powder has long been used as an herbal medicine. Its proponents claim that it can cure diabetes, can treat dementia, and inhibit the growth of cancer cells.

The powder is an ingredient in some dietary supplements and meal replacement products.

With two outbreaks still under investigation, consumers should be wary of using products that contain moringa powder or moringa leaf powder, especially as the most recent outbreak involves an extremely antibiotic resistant strain of Salmonella.

The dietary supplement capsules covered by the most recent recall have a a very long shelf life, extending through most of 2027. Consumers who purchased these products should check their medicine cabinets and kitchen cupboards for any bottles of the recalled products.

Consumers who experience symptoms of Salmonella (eg., high fever, dehydration, bloody diarrhea or diarrhea that won’t get better, or vomiting) should seek medical care immediately.

  • Most people with Salmonella infection recover without antibiotics. If antibiotics are needed, infections with this strain may not be treatable with commonly recommended antibiotics and may require a different antibiotic choice.
    • The Salmonella strain associated with this outbreak is resistant to all first-line and alternative antibiotics commonly recommended for the treatment of Salmonella infections.
    • This strain also might be resistant to multiple β-lactam antibiotics, including meropenem and other carbapenems, because it carries an NDM-1 carbapenemase gene.
  • Tailor antibiotic treatment to antimicrobial susceptibility testing results when possible.
  • Consider consultation with an infectious disease specialist for management of patients with extensively drug-resistant or complicated Salmonella infection.
