IRVINE, Calif. -- A woman eating a hot dog from a Costco food court in Irvine reportedly bit into a live 9mm round and later found what appears to be a bullet lodged in her stomach, according to a Local 6 News report.

Olivia Chanes, 31, told police she was eating the hot dog Sunday afternoon at the store in Irvine, about 40 miles south of downtown Los Angeles, when she bit into something hard and found what officers determined was a live round.

X-rays later found what appears to be another bullet in her stomach.

Police interviewed workers and opened all of the approximately 25 remaining hot dog packages after Chanes reported biting into the bullet, CEO Jim Sinegal said.

"We checked everything thoroughly," Sinegal said by phone from Costco's corporate office near Seattle. "Obviously, it's regrettable. ... The question is when could something like this happen."

The company CEO said he was not aware of any legal claim filed by Chanes. Police and the Orange County Health Department are investigating the incident.

Costco officials say they serve Hebrew National hot dogs, which are carefully prepared and pass through a metal detector at the factory.

"This is such an extraordinary thing," Singal said. "It's difficult to understand how this could have happened."
