At least 345 people in 27 states have been reported getting sick from the salmonella strain linked to the jalapeños. Most have been in Minnesota and Colorado. No deaths have been reported, but officials say 36 people have been hospitalized.

The Centers for Disease Control and Prevention said Wednesday that the chili peppers were moved into the U.S. by Coast Citrus Distributors. The company has recalled the peppers and is notifying its customers, which include some prominent Mexican food restaurant chains, officials said.

Coast Citrus Distributors didn’t immediately respond to a Thursday voicemail seeking comment.

The Food and Drug Administration said that of the 191 people interviewed in the outbreak investigation, 177 — or 93% — reported eating at a Mexican-style restaurant, including Chipotle Mexican Grill and Qdoba, from June 14 to July 14.

Chipotle Mexican Grill said Tuesday that it had removed jalapeños from some of its restaurants. Qdoba on Wednesday said the company had proactively removed jalapenos from all of its restaurants.

“Given their actions to remove product from their stores, neither of these establishments are considered a current ongoing risk to consumers in this outbreak,” CDC officials said in a statement.

The FDA is investigating whether any of the jalapeños went to grocery stores. The agency may announce additional actions on its recalls webpage, health officials said.

Mexico health officials said they opened an investigation and made a field visit Thursday to a packing plant in the northern state of Nuevo Leon.

Salmonella bacteria cause about 1.35 million infections in the United States every year, and outbreaks have been tied to sources such as cucumbers, eggs, unpasteurized milk, fresh basil, geckos and pet bearded dragons.

Within hours or days of being exposed to the bacteria, infected people can suffer from diarrhea, fever and stomach cramps. The illness usually lasts four to seven days, and most people recover without treatment.

Young children, retirement-age adults and people with weakened immune systems are at higher risk for more severe illness, according to the CDC.

Shares of Chipotle, based in Newport Beach, California, tumbled nearly 10% on Tuesday and have not recovered. A number of fast-casual chains like Chipotle have seen less foot traffic from middle- and lower-income customers due to broader inflation in the U.S., and recent headlines about foodborne illnesses may be another negative.
