The incident happened in the 6200 block of Topanga Canyon Boulevard around 1:30 p.m.
Authorities said a pizza restaurant employee flagged down Topanga area officers Paul Maldonado and Kurt Logan following the emergency. Maldonado and Logan propped up the unconscious woman, who they found lying on the ground, and began administering CPR.
Officer Logan said he and his partner continued to attempt to shake the loose food lodged in the victim's throat until paramedics arrived on the scene.
"When we walked in, I saw her on the floor to the rear of the restaurant and immediately started CPR," Officer Maldonado said. "Within minutes, we were able to get a pulse."
Officer Logan added, "I could see something lodged inside the woman's throat and tried to position her head to clear the object, while my partner did chest compressions until the paramedics arrived."
The woman was transported to a nearby hospital and is expected to be OK.
