NEW YORK — Mario Batali is giving up oversight of the daily operations at his restaurant empire following reports of sexual misconduct by the celebrity chef over a period of at least 20 years.

The online site Eater New York reported Monday that the incidents involve at least four women, three whom worked for Batali. In a prepared statement sent to The Associated Press, Batali said that the complaints "match up" with his past behavior.

"I take full responsibility and am deeply sorry for any pain, humiliation or discomfort I have caused to my peers, employees, customers, friends and family," Batali said.

A spokesperson for Batali & Bastianich Hospitality Group says an employee reported inappropriate behavior by Batali in October. The company told Eater it was the first formal complaint against Batali and that he was reprimanded and required to attend training.

Batali will also take leave from his ABC cooking show, "The Chew."

"We have asked Mario Batali to step away from The Chew while we review the allegations that have just recently come to our attention," the network said Monday. "ABC takes matters like this very seriously as we are committed to a safe work environment. While we are unaware of any type of inappropriate behavior involving him and anyone affiliated with the show, we will swiftly address any alleged violations of our standards of conduct."

Batali was well known in culinary circles, taking jobs early in his career as a sous chef at the Four Seasons in Santa Barbara and San Francisco.

Batali attended Rutgers University, and worked at the nearby Stuff Yer Face restaurant on Easton Avenue in New Brunswick.

NJMonthly quoted his commencement address to the Rutgers Class of 2005: “Yes, the agile Molto Mario mind … came into its own right here in New Jersey in a school that turned out to be a lot more demanding and inspirational than the more expensive schools a lot of people I know spent their time and daddy’s money at.”

He said his Stuff Yer Face experience showed that “you’ve got to get a brand,” the magazine quoted him saying.

His career took off after opening Po in New York City in the early 1990s, and he skyrocketed to fame with the airing of Molto Mario, a show that ran on the Food Network for eight years, until 2004. It was there that his signature look, a fleece vest, shorts, and orange Crocs, became instantly recognizable to most people.

He co-owns restaurants in a handful of cities. The Batali & Bastianich Hospitality Group owns or operates several restaurants, including Babbo in New York, Carnevino Italian Steakhouse in Las Vegas and Pizzeria Mozza in Los Angeles. It's also a partner in Eataly, an Italian food hall and grocer, which has locations in New York, Chicago and Boston.

Batali has long been socially active. The Mario Batali Foundation advocates child nutrition. He has come out forcefully against hydraulic fracturing, a method used to extract oil and gas.
