HIGHLANDS RANCH, Colo. -- A Denver-area family is speaking out to the Call7 Investigators about the frightening consequences of eating raw cookie dough.

The parents of Madison Sedbrook of Highlands Ranch are suing Nestle, the makers of Toll House refrigerated cookie dough, after their 6-year-old daughter was repeatedly hospitalized with symptoms from a potentially deadly strain of E. coli after eating the dough.

In a Call7 exclusive, Investigator Theresa Marchetta spoke with family members and learned they are demanding answers and accountability.

With a toothless smile and contagious laugh, Madison Sedbrook laughs and dances around her Highlands Ranch home.

Looking at her now, it is hard to believe that just a few short weeks ago her parents were fearing the worst.

"It was scary," said Madison.

"She had diarrhea and consistent vomiting," said her mother, Cindy Sedbrook.

"We knew something was wrong. We didn't know what," said her father, Tristan Sedbrook.

Madison's mother said she never suspected the cookie dough they had all eaten as a treat could make her daughter gravely ill.

"We ate a few squares raw and put it in our ice cream," said Cindy.

Her parents said Madison's symptoms worsened.

They said she had pain near her kidneys and blood in her stool.

After a brief hospital stay to locate the cause of her pain, Madison's parents were sent home.

"It was just wrenching for us. We felt really hopeless, constantly debating second opinions. Meanwhile, Madison was deteriorating pretty quickly," said Tristan.

Finally, the Sedbrooks said, Children's Hospital diagnosed Madison with HUS, or hemolytic uremic syndrome, a complication of the E. coli infection.

"She was in ICU for four days," said Cindy.

The Sedbrooks said at one point, Madison was hours away from dialysis, with less than 10 percent kidney function.

Call7 Investigator Theresa Marchetta asked the family if they had read the warning on the cookie dough label that says "bake before consuming."

Cindy said, "We've gotten the cookie dough so long you don't read the package every time you buy it."

"Sure there is that warning label," said Tristan, "but that does not absolve any company for liability such as E. coli in this product."

The Sedbrooks' lawsuit was filed by the Marler Clark law firm in U.S. District Court.

They said they are suing Nestle for damages for Madison's repeated hospital stays and also want to know exactly how a form of E. coli O157:H7 found in a cow's intestine ended up in the cookie dough Madison ate.
