By Maureen O’Hare, CNN(CNN) — Employees at an airline catering facility located next to Los Angeles International Airport have filed a safety complaint alleging exposure to maggots, mold, cockroaches and other vermin while they work to prepare food. The award-winning Flying Food Group has 19 catering facilities across the United States, preparing 120 million meals annually for more than 75 airlines. When contacted by CNN for this article, Flying Food Group said, “We are aware of the allegations that have been made regarding conditions at our facility.” “Workers are incredibly frustrated,” says Maria Hernandez, press secretary for UNITE HERE Local 11, the hospitality worker labor union that raised the safety complaint on behalf of employees. “Flying Food Group workers have spoken at the Board of Airport Commissioners about labor abuses on no fewer than 50 occasions, and yet the airport leadership has not taken meaningful action,” Hernandez claims.
