A food scandal involving somewhat ancient chicken feet, some of which were 46 years old, is creating a stir among netizens across China.

Police in Nanning, capital of the Guangxi Zhuang autonomous region, said they had confiscated more than 20 metric tons of low-quality and long-expired chicken feet from a frozen meat warehouse this weekend.

Chicken feet, or fengzhao, are a popular delicacy. They are often served as a cold dish and eaten with beer.
