Port-au-Prince , Haiti ( CNN ) -- Search-and-rescue efforts at a supermarket in Haiti 's capital have ended after teams determined no one else was alive beneath the rubble , an official told CNN Wednesday . A French excavation team was working at the Caribbean Supermarket on Tuesday . Several Haitians had been in the building at the time , looking for survivors or useful items . At least one of these foragers became trapped in the rubble . While the French team was trying to rescue that person , their excavation machine , which resembles a bulldozer , tipped into a hole and caused a further collapse , said Lt. Col. Christophe Renou of French Civil Protection . The French team called in U.S. and Mexican teams to help with the rescue . The U.S. team brought more radar and lifting devices to try to extract the known survivor and reach any others , said Norman Skjelbreia , an incident commander from the U.S. Army Corps of Engineers . But at 11 p.m. Tuesday , the teams determined there was no one else alive under the rubble , and they called off the rescue mission , Renou told CNN Wednesday . He said information gathered from radar and listening equipment detected no signs of life . The rescue was an extremely dangerous one , he said , with pieces of concrete shifting . At one point , he said , a female Mexican rescue worker was trapped under the rubble and teams had to work to save her life . It was decided that the safety of the search-and-rescue teams was more important than the search to retrieve bodies from the precarious collapsed building , Renou said . More than 212,000 people died in the January 12 earthquake , Haitian officials said . Caribbean Supermarket was the scene of a number of rescues after the earthquake , including the rescue of five people in one weekend . Rescuers pulled an apparent survivor of the original quake , Evan Muncie , 28 , from the rubble of another market on Monday . Doctors found him suffering from extreme dehydration and malnutrition , but without significant crushing injuries . CNN 's Ingrid Formanek contributed to this report .
