Chipotle Mexican Grill says it has identified a potential connection between its restaurants and an ongoing Salmonella outbreak being investigated by public health authorities.
In a statement released Tuesday, the company said it was informed that officials are investigating a supply chain-related Salmonella outbreak affecting multiple food service retailers. Using its ingredient traceability system, Chipotle said it identified jalapeños from a common lot as a potential shared ingredient and has proactively removed and replaced them at affected restaurants.
The company emphasized that the investigation is ongoing and that it is cooperating with public health officials to determine the source of the outbreak.

What Are the Symptoms of Salmonella?
Salmonella is a type of bacteria that causes foodborne illness, commonly known as salmonellosis. Symptoms typically develop between six hours and six days after exposure and often include:
- Diarrhea
- Fever
- Stomach cramps
- Nausea
- Vomiting
- Headache
Most healthy people recover within four to seven days without specific treatment, although dehydration can become a concern if diarrhea is severe.
Is Salmonella Fatal?
Most Salmonella infections are mild and resolve on their own. However, the illness can become serious if the bacteria spread beyond the intestines or if severe dehydration develops.
Young children, adults over 65, pregnant people, and those with weakened immune systems are at the highest risk for complications. In rare cases, invasive Salmonella infections can lead to hospitalization or death, making prompt medical attention important for anyone experiencing severe symptoms, bloody diarrhea, persistent high fever, or signs of dehydration.
Chipotle's History of Food Safety Incidents
Chipotle has faced several high-profile food safety incidents over the past decade, including outbreaks involving E. coli, norovirus, and Salmonella, prompting the company to overhaul many of its food safety practices.
Following the nationwide E. coli outbreaks in 2015, Chipotle implemented enhanced ingredient testing, centralized produce preparation for certain ingredients, supplier verification measures, and expanded employee food safety training. The company has also invested in ingredient traceability systems designed to quickly identify products that may be linked to an outbreak.
In its latest statement, Chipotle said that the traceability system enabled it to identify jalapeños from a common lot as a potential shared ingredient shortly after learning of the investigation.
What Is the Latest With Cyclospora Outbreaks?
The Salmonella investigation comes as public health officials continue to monitor Cyclospora infections, another foodborne illness that has frequently been linked to fresh produce.
Cyclospora is caused by a microscopic parasite rather than bacteria. While the symptoms—including prolonged watery diarrhea, fatigue, nausea, stomach cramps, bloating, and weight loss—can resemble other foodborne illnesses, Cyclospora infections often last longer if left untreated and typically require prescription antibiotics.
According to the CDC, the 2026 Cyclospora season has seen an unusually large increase in illnesses nationwide. Since May 1, the agency has received reports of 6,707 laboratory-confirmed domestically acquired cases and is aware of more than 11,500 additional cases that are either unconfirmed or still under investigation, with many reported by Michigan and Ohio. The CDC is investigating several clusters of infections, including a multistate outbreak linked to iceberg lettuce, and notes that reported case counts likely underestimate the true number of illnesses because many infections go undiagnosed or have not yet completed the reporting process. The agency says Cyclospora cases typically rise during the May-to-August season and has begun issuing weekly surveillance updates because 2026 case levels are significantly higher than those seen during the same period in 2025.
Although both illnesses can be traced to contaminated produce in the food supply chain, there is no indication that the current Salmonella investigation involving Chipotle is connected to ongoing Cyclospora cases. The two illnesses are caused by different pathogens and are investigated separately by public health officials.
What Happens Next?
As investigators work to determine the exact source of the Salmonella outbreak, Chipotle says it has already removed the potentially affected jalapeños from its restaurants and replaced them with product from different growers while the investigation continues.
