The Food and Drug Administration says a test shows that either a frog or a toad was in a Florida man's soda can, but it's not clear how it got there.

The FDA confirmed the remains of an animal were in Fred Denegri's can of Diet Pepsi. Denegri popped open the can July 23 as he was grilling dinner in Ormond Beach. He thought the animal was a rodent.

Pepsi spokesman Jeff Dahncke says the company is aware of the testing and stands by its manufacturing process. The can was traced back to a plant in Orlando that produces about 1,250 cans a minute.

Dahncke says the speed of production lines and rigorous quality control make it virtually impossible for a frog or toad to get into a can.

Denegri says he's certain the animal was in the can before he opened it.
