Three outlets of a burger and chicken chain restaurant in Shanghai will be hit with fines following a weekend swoop inspection by the market watchdog after the company became entangled in a food safety scandal.

A recent video shot by a vlogger at the Huoying outlet in Beijing of Wallace, a popular chain of restaurants, depicted a number of serious hygiene issues, such as staff serving customers with chicken nuggets that had fallen to the ground and detergent dripping into a frying pan.

There were also examples of flies on chicken ingredients, excessive use of cooking oil, and workers making burgers and fried chicken without wearing masks and gloves.
