Salmonella outbreak linked to jalapeños at Chipotle, Qdoba grows to 431 cases

A multistate Salmonella outbreak traced to jalapeño peppers served at Chipotle Mexican Grill and Qdoba locations has grown to at least 431 confirmed illnesses across 32 states, federal health officials said, with the case count climbing even after both restaurant chains stopped serving the implicated product weeks ago.

The Centers for Disease Control and Prevention's outbreak investigation page, last updated August 19, links the illnesses to a strain of Salmonella Javiana found in jalapeño peppers grown in Sinaloa, Mexico, and distributed in the United States by Coast Citrus Distributors. Fifty-seven people have been hospitalized. No deaths have been reported.

What happened

The outbreak first came into public view in early August, when the CDC issued a newsroom warning about the emerging cluster and the agency's outbreak summary page disclosed that dozens of illnesses had been traced back to Mexican-style restaurants, with a large share of interviewed patients specifically naming Chipotle and Qdoba, before the Food and Drug Administration joined the investigation into the supply chain. Illness onset dates for the cluster stretch from June 19 through August 2, meaning the contamination had been circulating for weeks before it was identified and traced to its source.

Coverage of the expanding case count, including reporting by NBC News on the restaurant chains' response and a detailed outbreak tracker maintained by Food Poisoning Bulletin, has followed the case count as it climbed from an initial 345 illnesses in 27 states to the current tally in the space of about two weeks.

Of 224 people interviewed by investigators, 91 percent reported eating at a Mexican-style restaurant in the days before falling ill, with meal dates concentrated between mid-June and mid-July. Chipotle began switching jalapeño suppliers at affected locations on July 20, and Qdoba stopped serving jalapeños altogether on July 28, both companies said, well before the outbreak's full scope became public. Coast Citrus Distributors subsequently halted imports from the implicated grower and agreed to a recall of the affected peppers.

The numbers

• 431 confirmed illnesses across 32 states as of the CDC's August 19 update, up from 345 cases in 27 states reported earlier in the month
• 57 hospitalizations, roughly 15 percent of patients with available medical information
• Minnesota and Colorado are the hardest-hit states, with 110 cases apiece
• Illness onset dates ranging from June 19 to August 2, with restaurant meal dates as early as June 14

Investigators found the outbreak strain showed reduced susceptibility to the antibiotic ciprofloxacin in a small number of samples, a detail the CDC is monitoring as part of its broader tracking of antimicrobial resistance in foodborne pathogens, though officials said it has not changed treatment recommendations for the illnesses identified so far.

How the recall has widened

What began as a restaurant-focused investigation has since expanded into the retail grocery supply chain. Taylor Fresh Foods recalled whole peppers and prepared foods containing them on August 8, covering products with sell-by dates through August 16. Whole Foods Market followed on August 12 with a recall of guacamole, pico de gallo, salsa and related condiments made with the affected jalapeños. Hardie's Fresh Foods recalled five-pound bags of jalapeños sold at Costco locations around the same time, and grocery chain NatureBest/H-E-B issued its own recall of prepared items sold in Texas and Louisiana on August 14.

The widening recalls reflect how far a single contaminated shipment can travel once it enters both restaurant and retail supply chains simultaneously. Health officials say the sprawl of this outbreak, now touching national restaurant chains, a regional produce distributor and multiple grocery retailers, is a reminder of how interconnected the fresh produce system has become, and how a single grower or shipment can affect consumers who never set foot in the restaurants where the outbreak was first detected.

The outbreak's reach spans both restaurant customers and grocery shoppers, though case demographics compiled by the CDC show a median patient age of 30, with 62 percent of those sickened being women. Illnesses have been confirmed across a broad geographic swath of the country, with the heaviest concentrations in Minnesota and Colorado alongside significant clusters in Illinois and Kansas. Symptoms of Salmonella infection typically include diarrhea, fever and stomach cramps, usually beginning between six hours and six days after exposure and lasting up to a week in most healthy adults, though the very young, elderly and immunocompromised face higher risk of severe illness requiring hospitalization.

"There is no ongoing risk at those restaurants now that the peppers have been removed."

That assessment from the CDC reflects the agency's view that the immediate restaurant-linked exposure has ended, even as the broader retail recalls continue and case counts from earlier exposures keep being added to the tally through the normal lag in laboratory confirmation and reporting. A Qdoba spokesperson said the company had "proactively removed jalapeños from all our restaurants" once it learned of the potential link, while Chipotle has said it acted "out of an abundance of caution" in switching suppliers even before health officials had confirmed the connection to its stores.

What happens next

The CDC and FDA say their investigation remains active as they work to confirm whether contaminated jalapeños reached additional grocery stores beyond those already named in recalls, and as laboratory results continue to come in for illnesses reported in recent weeks. Health officials are urging consumers who purchased loose or bagged jalapeños matching the recalled lots, or prepared foods made with them, to check product labels against the FDA's published recall notices and discard or return anything that matches.

Food safety researchers say the case count is likely to keep climbing for a time even though the source has been identified and removed from the supply chain, a pattern typical of outbreaks where the reporting lag between illness onset and laboratory confirmation can run several weeks. For consumers, officials say the practical guidance remains straightforward: avoid any recalled jalapeño products still in refrigerators or pantries, and seek medical attention for severe or prolonged gastrointestinal symptoms, particularly high fever, bloody diarrhea or signs of dehydration.
