2015 Salmonella Newport Outbreak, Chipotle Mexican Grill, Minnesota

Minnesota Department of Health (MDH) and Minnesota Department of Agriculture investigators reported an outbreak of Salmonella Newport among customers of 17 different Chipotle Mexican Grill restaurants. The MDH Public Health Laboratory detected two PFGE outbreak strains identified as PulseNet patterns JJPX01.0030 and JPX01.0011. In total 92 culture confirmed case patients were identified. Eighty-one (88%) of the 92 cases reported that they ate or likely ate at a Chipotle location before onset of Illness. Ten (12%) cases denied exposure to Chipotle and one (1%) case was secondary to a household member with Chipotle exposure. In addition to the confirmed cases, 34 persons met the definition as a probable case. Among the 115 (81 confirmed and 34 probable) cases, illness onset dates ranged from August 2 to September 27. Seventeen cases were hospitalized, 18 were seen at an emergency department and 54 sought care at an outpatient clinic. No cases died. Analysis of case control data showed that mild tomato salsa, carnitas and brown rice were significantly associated with illness. Tomatoes were implicated as the outbreak vehicle by an ingredient-specific analytic study, supported by internal product distribution information provided by chipotle corporate. The ultimate source of contamination (i.e., the tomato farm or packing house) was not identified.
