Nine people in California are confirmed sick with a dangerous form of E. coli — and six of them are children — following an outbreak linked to beef kofta served at The Kebab Shop restaurant chain. Federal genetic testing published June 1, 2026 has now confirmed what public health investigators have long suspected: the outbreak strain matched samples of raw ground beef kofta produced by Olympia Food Industries Inc., in Franklin Park, Illinois, and distributed to Kebab Shop locations in California, Texas, and Florida. Five of the nine patients required hospitalization. Two children developed hemolytic uremic syndrome (HUS) — a potentially fatal kidney failure condition that is the most feared complication of Shiga toxin-producing E. coli infections.
The California Department of Public Health (CDPH) confirmed the nine California cases with illness onset dates ranging from March 27 through April 30, 2026. The U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS)issued a formal public health alert on May 24, 2026, noting that the implicated beef kofta was produced by Olympia Food Industries Inc. (Establishment 18743) in Franklin Park, Illinois on January 6, 2026. The Kebab Shop stopped selling the beef kofta product at all of its restaurant locations on May 18, 2026, meaning the risk of new exposure from this product is not ongoing. A formal recall was not issued because no products remained for sale at the time of the alert.
The Genetic Evidence That Sealed the Case
In the world of foodborne illness investigation, whole-genome sequencing (WGS) is the gold standard for linking sick people to a food source. It generates a genomic fingerprint of the bacteria isolated from patients' stool samples and compares it to bacteria isolated from food or environmental samples. When those fingerprints match closely enough, they indicate that the people and the food source share the same bacteria — meaning the food is the likely source of illness.
Whole-genome sequencing conducted by FSIS confirmed that the beef kofta samples collected from Olympia Food Industries and the outbreak strain infecting patients are genetically linked. The CDPH and FSIS have jointly concluded that grilled beef kofta served at The Kebab Shop is the likely source of the outbreak.
"We immediately stopped all sales of ground beef (beef kofta) nationwide on May 18, 2026, after CDPH linked the product as a potential source of the outbreak," The Kebab Shop CEO said in a statement. "As a result, there is no ongoing risk associated with this issue."
What HUS Is and Why It Is So Serious in Children
The two children who developed hemolytic uremic syndrome are the most serious cases in this outbreak. HUS is a life-threatening complication that occurs in approximately 5 to 10 percent of people infected with E. coli O157:H7, particularly children under age 5. The Shiga toxins produced by the bacteria enter the bloodstream and attack the tiny blood vessels in the kidneys, triggering a cascade of events that can lead to acute kidney failure, severe anemia from destruction of red blood cells, and dangerous drops in platelet counts — which can cause uncontrolled bleeding.
Children with HUS typically require intensive hospital care, which may include dialysis if kidney function fails severely. Most children survive with appropriate treatment, but some suffer permanent kidney damage, and a small percentage die. The CDC notes that HUS is most common in children under age 5 and in older adults, and that it represents the leading cause of acute kidney failure in U.S. children.
What Consumers in Affected States Should Know
Any person who ate beef kofta at The Kebab Shop and develops symptoms of E. coli infection within 10 days of exposure should contact their healthcare provider immediately. Symptoms of Shiga toxin-producing E. coli (STEC) infection include severe stomach cramps, diarrhea — often bloody — and vomiting. Symptoms typically begin 3 to 4 days after exposure. Most healthy adults recover within a week without treatment, though antibiotics are generally not recommended for STEC because they may increase HUS risk.
Warning signs of HUS developing in a child include decreased urination, unusual fatigue, pale skin, easy bruising, and blood in urine. These require emergency medical attention.
Frequently Asked Questions
Q: What caused the E. coli outbreak linked to The Kebab Shop?
A: Beef kofta (seasoned ground beef kebabs) served at The Kebab Shop restaurant chain, produced by Olympia Food Industries Inc. in Franklin Park, Illinois on January 6, 2026. Whole-genome sequencing confirmed the genetic link between the food product and the E. coli O157:H7 strain sickening patients.
Q: How many people were affected and how serious were the cases?
A: Nine confirmed cases in California, with illness onset dates from March 27 to April 30, 2026. Six of the nine are children. Five were hospitalized. Two children developed HUS — a potentially fatal kidney failure condition.
Q: Is the outbreak still ongoing?
A: The Kebab Shop removed beef kofta from all locations nationwide on May 18, 2026. Public health officials have stated there is no ongoing risk from this product. The outbreak investigation is still open but exposure risk is not continuing.
Q: Who should be most concerned?
A: Anyone who ate beef kofta at The Kebab Shop between March 27 and May 18, 2026, particularly if they are a parent of a child who did so and experienced any gastrointestinal illness in the days following.
Q: What were the symptoms and when do they appear?
A: Severe stomach cramps, bloody or watery diarrhea, and vomiting typically starting 3 to 4 days after exposure. Symptoms warrant a medical visit if they include bloody diarrhea, are severe, or develop in a child under age 5.
