Health Authorities Investigate Cluster of Brucellosis from Raw Cheese in Los Angeles County

Posted in Our Blog,Outbreaks & Recalls on May 26, 2026

A cluster of Brucellosis from raw cheese has been reported in Los Angeles County.

When a cluster of brucellosis illnesses was identified, the Los Angeles County Department of Public Health initiated an investigation. A common food was identified. That is when they discovered the raw cheese connection.

While the investigation is ongoing, very little information is available to the public.

Here is what we know so far about the outbreak of brucellosis from raw cheese in Los Angeles County.

Brucellosis from Raw Cheese

Los Angeles County has not released many details regarding this cluster of brucellosis from raw cheese. There are, however, some details we can report.

What We Know So Far:

  • Several adults were diagnosed with Brucella melitensis
  • Cases originated in South Los Angeles County.
  • Each sick person reported consuming unpasteurized cheese.
  • The cheese identified was imported from Mexico.
  • Brucellosis, while rare, is a possible germ harbored in raw cheese and other raw dairy products.

What We Don’t Know Yet (But Want to Know):

  • The brand or manufacturer of the suspected raw cheese outbreak source.
  • Is the cheese available for purchase on store shelves. If so, where is it sold?
  • Why hasn’t there been a recall for this product?
  • How many people have been infected so far?

What is Brucellosis and How Do You Get Brucellosis from Raw Cheese?

Brucellosis is the rare illness caused by infection with Brucella bacteria. It is sometimes called “Malta fever,” “Mediterranean fever,” or “undulant fever.”

Complicating matters most is the long incubation period (anywhere from one to four weeks and up to six months) and the non-specific symptoms.

The long incubation period makes connecting a food source to the illness more complicated.

Brucellosis Symptoms

Symptoms of brucellosis can be hard to pin down to the rare illness. That is, unless you have symptoms severe enough to seek medical attention and mention to your health care provider your raw dairy consumption.

Specialized tests are required to determine if you infection is caused by Brucella bacteria.

Common symptoms include:

  • acute or insidious onset of fever
  • night sweats
  • arthralgia (joint pain)
  • headache
  • fatigue
  • anorexia/loss of appetite
  • myalgia (muscle pain or aches)
  • weight loss
  • arthritis or spondylitis (a type of chronic arthritis involving inflammation of joints, ligaments, and tendons of the spine)
  • meningitis (inflammation of brain/spinal cord)
  • focal organ involvement
    • endocarditis (inflammation if inner lining and valves of the heart)
    • orchitits/epididymitis (inflammation of the testicle)
    • hepatomegaly (enlarged liver)
    • splenomegaly (enlarged spleen)

Delayed or inadequate treatment can lead to serious illness and severe chronic infection.

How Is Brucellosis Treated?

The standard treatment protocol for brucellosis involves 6 weeks of doxycycline and rifampin, in addition to 14 to 21 days of streptomycin.

Pediatric or pregnant patients often receive additional treatment.

If you have recently consumed raw dairy products or have other risk factors, your health care provider will likely start treatment right away. Even before confirmatory laboratory results have arrived. This helps reduce potential risks for additional complications.

How Common is Brucellosis?

Brucellosis is rather rare. But it is highly infectious. It does not take much to become sick and the germ is easily aerosolized. In fact, laboratories require physicians to alert them if brucellosis are suspected when submitting specimens. They are handled differently to protect the laboratory technician.

Los Angeles County Department of Public Health indicate that they receive fewer than 15 cases each year. Most of which are linked to unpasteurized imported cheese, those who work with animals abroad, or accidental laboratory exposures.

In the United States, brucellosis is rare. That is not the case in other parts of the world. Somewhere between 1.6 and 2.1 million new cases of human brucellosis are estimated across the world each year.

Brucellosis is often under reported.

This is due to several factors.

The wide range of nonspecific symptoms often lead to misdiagnosis. So symptoms are often attributed to other illnesses. Additionally, diagnostic laboratory facilities and the trained personnel necessary to diagnose the disease effectively are not available in all parts of the world. Especially in areas where Brucella bacteria are endemic.

Los Angeles County Department of Public Health Says Risk to General Public Is Low at This Time

According to a press release, the Los Angeles County Department of Public Health says that “while the risk to the general public at this time is low, this cluster of a rare infection is an important reminder that consuming raw or unpasteurized dairy products carries significant risk of infection.”

So, what exactly does unpasteurized cheese or dairy products mean?

What Does Raw Dairy Mean?

Raw milk, raw cheese, or raw dairy products are terms used for products made from milk that has not been pasteurized. Meaning, it has not undergone heat treatment through a process that kills potential illness-causing germs often associated with dairy products. Germs like the Brucella bacteria indicated in this outbreak of brucellosis from raw cheese in Los Angeles County.

But it isn’t new technology.

Pasteurization is a widely used process invented in 1864, by the namesake inventor, Louis Pasteur. Pasteur discovered a way to heat treat beverages in order to kill harmful microorganisms. The types of microorganisms responsible for diseases such as listeriosis, typhoid fever, tuberculosis, diphtheria, Q fever, E. coli infections and brucellosis.

The original intent for pasteurization was to help increase the shelf life and reduce spoilage of beer, wine, and other beverages. As you can imagine, a pressing issue of the time.

Today, it is most commonly associated with milk. Though juices and certain shelf stable foods are also commonly pasteurized. Historically, many foodborne illnesses prior to pasteurization were linked to milk and dairy products. A problem that has almost entirely been eradicated since widespread use of pasteurization.

In fact, since the mainstream application of pasteurization, the number of milk-related outbreaks has decreased from 25% to only 1%. With 70% of those outbreaks involving raw milk.

Raw milk is risky because without the heat treatment of pasteurization, potential germs found on dairy farms can make their way into the milk and sicken the consumer.
