A question remains to be answered: Why is it always the media and not the food safety regulators that uncover the illegal activities of food enterprises? The Shanghai Food and Drug Administration required the enterprises involved to remove the harmful food only, and did not order them to close down until the media put heavy pressure on them. The food safety authorities need to perform their duties better because those duties concern our health and lives.

"The regulations are not flexible, but we are." These words of a member of staff who processed the expired meat are more shocking than the scandal itself.

When food safety scandals happen, people tend to blame low standards or bad law enforcement, and few notice morality. Actually, the current scandal and some other incidents involving public safety show that China faces a serious moral decline. Morality is especially important in the food industry where information asymmetry exists and consumers have no way of knowing how the food they eat is processed.

Morality might be a luxury for the involved enterprises. By neglecting consumers' safety, the enterprises have failed their most basic duty of obeying the law and they must pay for that.
