Los Angeles education chiefs said today they withdrew permission for Jamie Oliver to film his healthy eating series in the city's schools because they did not want to be involved in reality TV.
The city's Unified School District spokesman Robert Alaniz said the celebrity chef had been filming for two weeks at one school, but a decision was made to ban him from others because he failed to submit a proposal about his plans to officials.
The filming permit for Oliver's ABC campaigning series, Jamie Oliver's Food Revolution, was then terminated.
"We decided to put a halt to it until we receive that proposal," said Mr Alaniz.
"We really don't want to be part of reality TV. The success formula for reality TV is drama and conflict. We're just not interested in either.
"This serves as a wake-up call. We're not interested in participating in reality TV across the district. We just don't want to go there."
Mr Alaniz said the district was not keen to be part of another reality TV production after he said NBC school makeover show School Pride left behind a sub-standard paint job at Hollenbeck Middle School last year that cost the district £72,000 to repair.
But he said the authority would continue to allow fiction and documentary productions.
A spokeswoman for the network said production on the series would continue, but declined to comment specifically on Oliver's ban from Los Angeles schools.
Mr Alaniz said Oliver had been filming at West Adams Preparatory High School and was due to film at Manual Arts Senior High School and Santee Education Complex before he was banned.
According to a transcript, a day after the ban, Oliver told the UCLA School of Public Health: "The school fought for me to get into their school, as did the teachers and the parent groups.
"Yesterday my filming permit was terminated because I can't promise that the LAUSD doesn't look good.
"Guys, I'm a British citizen. I love your country. I'm here not because I want to improve my TV career because I have a perfectly good one."
The first season of Oliver's TV show featured the chef attempting to revolutionise the eating habits and food policies of Huntington, West Virginia.
The town, which was not always thrilled to have the "Naked Chef" there, was selected after a 2008 story by The Associated Press dubbed the area America's unhealthiest.
