How an Alleged Blue Bell Listeria Victim Says the Illness Changed His Life Forever

It started with a brutal headache, and soon David Shockley was unresponsive.

Shockley, now 32, is not among the official 10 Blue Bell-linked listeria cases reported by the CDC, but according to a suit he filed against the company, the ice cream products he consumed before his illness were the only ones that could have been tainted with the deadly bacteria.

"He fully understands what happened to him," Eric Hageman, one of his lawyers, told ABC News, noting that his client is "a very smart guy."

"While his whole life has obviously changed, he is truly committed to doing everything he can to get back some semblance of the life he used to have," Hageman added.

"Several hours later, he lost consciousness," it says.

When people realized he was missing, he was found alive but unresponsive and rushed to the hospital, where he was placed in intensive care, according to the suit. His temperature was 106 to 107 degrees, and he was "in acute respiratory failure, septic shock and suffering from seizure encephalopathy." He spent five days on a respirator and regained consciousness on the sixth day, the lawsuit states.

"To his horror, when he did regain consciousness, he was unable to walk, talk, swallow or move much of his body," the suit says, adding that he spent 18 days in the ICU and another few weeks of rehab.

But he couldn't go home, the suit says. He had to return to his childhood home in Maryland.

Shockley has "significant coordination difficulties," which affect everything from balance to speech as well as and other neurological problems, Hageman said. According to the suit, his condition is "permanent."

A spokeswoman for Blue Bell said company officials "are aware of the lawsuit that has been filed, and we take all such matters very seriously."

"That said, we hope people will understand that because this situation involves litigation, we are not able to discuss any details of the matter," the spokeswoman added.

"We've always worked to make the very highest quality ice cream," Blue Bell CEO and President Paul Kruse said in a statement on April 24 when the company announced its reboot. "We intend to make a fresh start and that begins with intensive cleaning and enhanced training. This is a paradigm shifting event at Blue Bell and we want to put in place new systems to drive continuous improvement."
