"Literally maggots all over the box," Newsome said. "It was downright disgusting. You can actually see how many are living in the icing."
WFTV reporter Janai Norman was shown the maggots, inching around as soon as Newsome opened one of the packages still in the box she said she bought last Saturday at the store on Clearlake Road in Cocoa.
She said it was Sunday morning when her 9-year-old daughter took a few bites from the first package, before noticing the maggots.
"She screamed, she said, 'Mommy, daddy, there's something living in my Pop-Tart and it crawled in my mouth!'" Newsome said.
With a marked expiration date of Oct. 3, 2015, the Pop-Tarts should be good for another three months.
"They're literally living inside the filling and living inside the crust, where they were coming out of the crust. So, the question is where are maggots coming from? It had to come from the factory," said Newsome.
A statement from Kellogg's said they "believe this is an isolated incident that occurred after the product left our control."
Winn Dixie said it's working with Kellogg's to understand the source of the issue, and it has "removed the product from sale" until it can be certain it's safe to eat.
"It's terrifying to see maggots through a Pop-Tart," said Newsome. "I think they should take everything off the shelves from that brand, because they need to inspect all the food."
Kellogg's has not said whether it is recalling the product.
