Jalapeños served at Chipotle restaurants in Minnesota have been linked to at least 110 infections of Salmonella Javiana, according to both the Minnesota Department of Health (MDH) and a statement from the fast-casual Mexican restaurant chain. 

“We immediately initiated our ingredient traceability system and were able to identify jalapeños as a potential common ingredient from a common lot, and the restaurants where it was distributed,” Chipotle said in a statement issued yesterday. “Out of an abundance of caution, we proactively removed the jalapeños from our restaurants and replaced them with product from different growers.”

Among the 84 patients interviewed by Minnesota investigators, 75 reported eating at Chipotle before getting sick, with symptom onset between June 14 and July 14.

MDH senior epidemiologist supervisor Carlota Medus, PhD, MPH, told The Wall Street Journal that jalapeños are the suspected vehicle for the bacteria. Medus also said it’s likely the jalapeños were served at other Mexican-style quick-service restaurants.

Medus told other media outlets it was too soon to tell if the outbreak was ongoing but was encouraged by Chipotle’s cooperation.
