LOUISVILLE, Ky. (WDRB/CNN) -- Papa John's CEO Rob Lynch has responded to accusations by founder and former CEO John Schnatter, telling CNBC in an interview that the recipe for the pizza has not changed.

"No, actually, nothing has changed." Lynch said.

Papa John's founder John Schnatter said he has eaten 40 pizzas in 30 days and believes the product has gotten worse. Schnatter didn't literally eat 40 pizzas, but he typically orders and serves Papa John's when making public appearances.

"The way they're measuring the pizza, the way they're putting the pizza together is just not fundamentally sound to what makes a Papa John's pizza," Schnatter said.

But Lynch disputes Schnatter's claim.

"I've never been a part of a system that takes more pride in what goes into the food that we're making and how we're making it," he said. "We feel great about the food that we're putting out there. We haven't made any changes to the way we make it or to what goes into our products."

In an exclusive interview with WDRB's Stephan Johnson in November, Schnatter accused the company of changing the way the pizzas are made.

Schnatter also criticized Lynch.

"He has never been a CEO. He has no pizza experience," Schnatter said. "He has never been in the pizza category. He doesn't really know quality. Probably most important, he doesn't have a passion for people."

Lynch said that Schnatter is "entitled to his opinion" and that he "can't comment on how he feels or what he thinks."
