Chipotle Stock Tanks on Potential Salmonella Outbreak Tied to Jalapeños -- Barrons.com

By Evie Liu

Chipotle Mexican Grill removed jalapeños from several Minnesota restaurants after state health officials linked the peppers to a salmonella outbreak that has sickened at least 110 people.

Chipotle shares fell as much as 8.5% in Tuesday trading, their largest intraday decline since Oct. 30. The market reacted sharply because Chipotle has a history of food-safety problems.

The selloff suggests investors remain sensitive to any foodborne-illness headlines involving restaurant companies, even when the contamination may have originated with an outside supplier and management acted quickly.

Chipotle said it removed the suspected peppers from every restaurant that received them and replaced them with jalapeños from other growers after learning of a possible supply-chain outbreak affecting multiple food-service companies.

Minnesota officials said Chipotle has fully cooperated with the investigation and that they are no longer concerned about continued exposure at the chain's restaurants, The Wall Street Journal reported. However, contaminated peppers could still be served elsewhere, the officials said.
