China’s growing food delivery market has hit a snag after the country’s state broadcaster aired a scathing report against the industry’s biggest player.

Ele.me, the Shanghai-based online food delivery service backed by Alibaba, Tencent and JD.com, was singled out in CCTV’s annual “3.15” investigative TV program on Tuesday for allowing unqualified workers to deliver potentially unsanitary food to its customers.

“You think you ordered food as pretty as in the pictures, but they were in reality made in unlicensed and filthy shacks that will cause you to vomit,” the program said.

The exposé was soon followed by an announcement from the food and drug regulators in Shanghai and Chengdu on Wednesday to conduct investigations on Ele.me.

Ele.me, which delivers to more than 300 cities across China, quickly issued an apology to the public and vowed to take the necessary measures to avoid such incidents in the future.

“It is with a heavy heart that I find that the company we are so proud of has triggered such food safety concerns,” Ele.me CEO Zhang Xuhao said in a statement on Wednesday.

Zhang said the company will implement tougher food safety checks, remove the offending restaurants from its platform, and launch an internal investigation to rectify the situation.
