This will be an interesting story to follow. My guess is a supplier failed to report an injury at their plant, even though it is against the law. Happens all the time, I know!
A woman said she bit into a partial finger served in a bowl of chili at a Wendy's restaurant, leading authorities to a fingerprint database Thursday to determine who lost the digit.
The incident Tuesday night at a San Jose, Calif., Wendy's restaurant left the unidentified customer ill and distraught, said Joy Alexiou, a spokeswoman for the Santa Clara County Health Department. Employees at the Wendy's were checked and the fingertip didn't come from any of them, officials said, adding that the well-cooked finger may have come from a food processing plant that supplies the company.
