Chipotle Mexican Grill Inc said it would reopen all 43 restaurants in Seattle and Portland after health officials found no evidence of E. coli bacteria at those outlets.
The company had closed the restaurants on Oct. 31 after health officials linked 11 Chipotle outlets to some cases of food poisoning caused by the bacteria.
Health officials concluded that there is no ongoing risk from the incident, Chipotle said on Tuesday.

Shares of the company, known for using organic ingredients and antibiotic-free meat, were up 2.4 percent at $623.96 in morning trading.
The Oregon Health Authority had said on Nov. 1 that three cases of E. coli in Oregon and at least 19 in Washington had been linked to eating at Chipotle restaurants since Oct. 14.

On Monday, health officials said food samples taken from the restaurants found no presence of E. coli bacteria.
Food outbreak investigations do not always identify a specific food source as the culprit, because contaminated food is at times consumed before the samples are collected, the Washington health department has said.

Up to Monday's close, Chipotle's shares had fallen nearly 5 percent since the company announced the closure of restaurants.
