The "disgusting" blob that Fred DeNegri's wife says she poured out of his Diet Pepsi can was probably a gutted frog or toad, the Food and Drug Administration said.
DeNegri was grilling in his backyard tiki bar in Ormond Beach, Florida, when he popped open a can of Diet Pepsi, took a big gulp and started gagging, his wife, Amy, said.
He emptied out the can down a sink but something heavy remained inside. His wife took over and shook the can over a paper plate until something resembling "pink linguini" slid out, followed by "dark stuff," Amy DeNegri said.
"It was disgusting," said Amy DeNegri, 55. "And now, what started out as a normal afternoon in our tiki bar has blown up into this crazy thing."
The DeNegris took pictures before calling poison control and the FDA, which showed up the next day to examine the can in question and collect it for lab testing.
