Sources said the ministry had examined the contents of two episodes of the show after it received complaints.
A court had also asked the ministry to examine the content aired on the show, they said.
"There had been concern about the language used by some contestants in a conversation that was aired on the reality show Bigg Boss 7. In one of the episodes of the show, a contestant is shown sitting on an electric chair and being given electric shocks," an official source told PTI.
"It was felt that the content exhibited was not suitable for unrestricted public exhibition and prima facie it is violative of the programming code under the Cable TV Act so the ministry has issued a show cause notice and asked the channel to explain," the source said.
