Dozens of patients reported eating at Chipotle.
Minnesota officials have identified 110 salmonella cases connected to the investigation. Of the 84 patients who were interviewed, 75 said they had eaten at Chipotle between June 14 and July 14, according to Reuters.
That represents nearly 90% of the interviewed patients. Still, investigators found that contaminated food may also have been served at other Mexican-style, quick-service restaurants.
Carlota Medus, a senior epidemiology supervisor with the Minnesota Department of Health, said evidence collected so far shows that the food responsible for the illnesses reached restaurants beyond Chipotle. Officials have not publicly identified all the additional businesses involved.
The department said Chipotle had cooperated with investigators and acted after learning about the suspected outbreak.
Health officials said they did not have an ongoing concern about the chain following the removal of the affected peppers.
The wider risk remains less clear. Investigators have warned that it is too early to determine whether the outbreak has ended or whether potentially contaminated ingredients may still be served elsewhere.
A common batch of peppers drew attention.
Chipotle said it activated its ingredient-tracing system after being notified about the illnesses. The company identified jalapeños from a common lot as a possible ingredient connecting the affected restaurants.
The peppers were removed from all Minnesota locations and other restaurants that had received products from the suspected batch. Chipotle has not publicly named the grower or supplier connected to the first shipment.
Fresh produce can create difficult challenges during foodborne illness investigations. Unlike packaged products carrying clearly visible batch numbers, peppers may pass through farms, packing facilities, distributors and restaurant kitchens before investigators begin tracing them.
Jalapeños are also commonly served raw or lightly processed, which means there may be no cooking step capable of killing harmful bacteria before the peppers reach a customer’s meal.
The investigation has not produced a final determination that jalapeños caused the outbreak. The peppers remain the suspected source based on patient interviews, restaurant records and supply-chain information.
Federal investigators are tracing the supply chain.
The Food and Drug Administration is leading the federal traceback investigation. That process comprises examining records from restaurants, distributors and growers to determine where a suspected ingredient originated and which businesses received it.
Minnesota officials said other states are contributing information to the investigation, suggesting the affected supply chain may go beyond Minnesota.
Authorities have not yet released a complete list of states, restaurants or suppliers involved.
The FDA’s active outbreak table listed an ongoing Salmonella Javiana investigation involving 212 cases as of July 29. At that time, federal officials had not publicly identified the food responsible, although traceback and sampling work had begun.
Officials may revise case counts as laboratory results arrive and investigators connect additional illnesses to the outbreak. There is often a delay between the moment a person becomes sick, seeks treatment, receives test results, and is formally counted in an outbreak investigation.
Chipotle’s quick response did not calm investors.
The announcement immediately revived concerns about food safety at one of America’s largest fast-casual restaurant chains.
Chipotle shares fell more than 9% during Tuesday afternoon trading after news of the outbreak investigation became public. Investors appeared to focus on the possibility that another food safety scare could damage restaurant traffic and customer confidence.
The market reaction was especially sharp because Chipotle has spent years rebuilding its reputation following several outbreaks between 2015 and 2018. Those incidents included cases involving E. coli, Salmonella and norovirus.
This time, however, the suspected contamination appears to involve an ingredient supplied to several restaurant businesses rather than a problem isolated inside Chipotle kitchens.
Health officials have also pointed out the company’s cooperation and rapid removal of the peppers.
Chipotle said protecting guests and employees remained its highest priority. The company maintained that its traceability procedures allowed it to identify the restaurants that received peppers from the suspected lot and replace them quickly.
Symptoms may appear days after exposure.
Salmonella infections commonly cause diarrhea, fever, and painful stomach cramps. Some patients may also experience nausea, vomiting, headaches or loss of appetite.
Symptoms usually begin between six hours and six days after exposure and generally last four to seven days. Most people recover without specialized treatment, although dehydration can become dangerous, particularly for young children, older adults and people with weakened immune systems.
Medical attention may be necessary when diarrhea or vomiting lasts longer than two days, stool contains blood, fever rises above 102 degrees Fahrenheit, or signs of dehydration develop. Those signs can include dark urine, reduced urination, extreme thirst, dizziness, and a dry mouth or throat.
For now, the missing jalapeños at affected Chipotle restaurants represent only the most visible part of a much larger investigation. The central question is no longer simply whether one restaurant chain served contaminated peppers. It is how far the suspected batch traveled before health officials recognized the pattern.
