ORLANDO, Fla. - After finding a 5-inch frog in a can of Diet Pepsi, federal officials inspecting a Pepsi manufacturing plant were concerned that procedures to clean out the cans weren't fully tested, according to a newly released report.

The inspection report from the Food and Drug Administration also states the Orlando plant has had 13 consumer complaints of alleged foreign objects inside cans since 2007, including the July 23 complaint about the frog - initially thought to be a mouse - from an Ormond Beach, Fla., couple.

Despite that, FDA officials decided that the plant passed inspection and didn't find any violations, according to the report obtained by the Orlando Sentinel through a Freedom of Information Act request.

"In cases where a foreign object is reported to be in a product consumers eat or drink, the FDA is immediately concerned and acts to address the matter," said Tom Gasparoli, a media officer with the FDA. "Our investigation of this case in Orlando is ongoing."

Gasparoli couldn't comment on the inspection report, but did add: "The FDA encourages consumers to come to us with their complaints."

Meanwhile, the consumer who found the frog in the can, Amy Denegri of Ormond Beach said she and her husband, Fred, would like an apology for what happened.

"We had no intention of suing, but it's more of a matter of how Pepsi handled it and treated us," she said.

Pepsi officials released a statement Tuesday to the Sentinel that said: "We have thoroughly examined our production records and remain confident that this did not occur during our manufacturing process. We gave FDA complete access to our facility for several days and they did not raise any concerns or ask us to make any changes to our operations. We are fully confident in the quality and safety of every product we sell."

Fred Denegri had opened the can of Diet Pepsi in July, just as he and his wife were making dinner, and took one swig of the soda, which he found foul-tasting.

They realized something lurked inside the can and originally thought it was a rodent. Amy Denegri contacted the FDA, which analyzed the can and its contents.

An FDA inspector confirmed that it was an amphibian, estimating the frog or toad was nearly 5 inches long, according to a report. The can had not been tampered with and appeared to be a normal aluminum can with an opened tab, the report said.

In August, three FDA investigators visited the Orlando plant to review the manufacturing process, according to an inspection report. They reviewed the various steps in the process and interviewed 14 managers and supervisors.

FDA officials also found a consumer-complaint log, listing 13 complaints of foreign objects in cans since 2007. The federal inspectors asked for documents showing how Pepsi handled those complaints, but Pepsi officials didn't have documents to give them, telling inspectors that many of them were handled verbally, according to the FDA report.

Federal inspectors had some concerns about what they found, including questions about whether the plant's air rinser, used to clean empty cans before they are filled with soda, had been tested and proved to remove any foreign objects that might cling to the side of the can, the report said.

The FDA officials also noted there were no tests or reports that verify that the plant's manufacturing procedures and staff observations could make sure that a can with a foreign object inside would have been rejected before leaving the plant. Inspectors recommended additional checks to make sure there is nothing inside the cans before they are filled.

Overall, there were no major objections and no major changes necessary at the plant, the FDA report said.

Amy Denegri said she was glad that she consulted the FDA first after finding the animal. She said after news accounts about her can were publicized, other consumers had contacted her, saying they had problems with Pepsi cans, too.

"I felt the public needed to know," she said. "These are things behind closed doors most of the time."
