Chipotle founder and co-Chief Executive Officer Steve Ells on Thursday apologized to patrons who fell ill after eating at the company's restaurants, and pledged that sweeping new food safety practices will prevent such outbreaks in the future.
"This was a very unfortunate incident and I'm deeply sorry that this happened, but the procedures we're putting in place today are so above industry norms that we are going to be the safest place to eat," Ells said in an interview on NBC's Today program.
His comments come a day after local health officials reported that 80 people had been sickened by norovirus linked to a Chipotle Mexican Grill Inc restaurant in Boston, in the latest wave of patrons who have fallen ill on the heels of another outbreak in the Northwestern United States.
That finding appears separate from a spate of E. coli infections in recent months that has sickened 52 people in nine states and forced the company to temporarily close some locations.
The burrito restaurant chain has been under scrutiny since November, when health officials first linked it to the E. coli outbreak, the company's third food safety incident since August.
The illnesses have raised concerns about potential damage to Chipotle's reputation despite the loyalty it has built over its use of fresh produce, meat raised without antibiotics and ingredients free of genetically modified organisms, or GMOs.
Some critics have said the food safety concerns raise questions about the fast-growing brand, and shares of the company have fallen from a year-high in August, when the incidents began.
Asked whether the company could recover financially, Ells said "certainly," a sentiment some analysts shared.
"We see value in shares from current levels for investors that can look through the potential near-term choppiness," William Blair analysts wrote in a research note.
After Ells's comments, shares of Chipotle were up 3.6 percent at $567.71 in premarket trading on Thursday. The stock has fallen about 20 percent this year.
Ells said the affected Boston restaurant would reopen after being completely sanitized and having all of its employees tested for norovirus, which is highly contagious and spread easily through contaminated food and surfaces.
More than 120 people in the northeastern U.S. city reported symptoms.
Regarding the E. coli outbreak, Ells said the U.S. Food and Drug Administration has still not found an exact source for the bacteria, which can cause severe diarrhea and vomiting.
He said Chipotle's new food safety procedures will put it 10 to 15 years ahead of industry standards.
"We're doing a lot to rectify this and to make sure this doesn't happen again."
