14-year-old Kayla Boner of Monroe, Iowa, died last week from E. coli and kidney failure.

Boner’s parents, Rick and Dana Boner, told KCCI that when their daughter first got sick, they thought she had the flu.  But after two days, she wasn’t getting any better

Dana and Rick Boner say it’s hard to move forward without knowing what caused their daughter’s infection.  They can’t help but wonder about recent frozen pizza recalls because of E. Coli contamination.

"They have taken some of our Totino’s pizza rolls to test at the labs," Dana Boner said.  "She had pizzas but there’s none left so there’s nothing to test."

Deaths are a sobering reminder that food safety is not simple. Our condolences to the family.
