They worry – are the steamed buns real or "recycled?"
And what about the eggs?
Chinese consumers are concerned about fake or adulterated food. From The New York Times:
"…China’s news media have reported sales of pork adulterated with the drug clenbuterol, which can cause heart palpitations; pork sold as beef after it was soaked in borax, a detergent additive; rice contaminated with cadmium, a heavy metal discharged by smelters; arsenic-laced soy sauce; popcorn and mushrooms treated with fluorescent bleach; bean sprouts tainted with an animal antibiotic; and wine diluted with sugared water and chemicals.
Even eggs, seemingly sacrosanct in their shells, have turned out not to be eggs at all but man-made concoctions of chemicals, gelatin and paraffin. Instructions can be purchased online, the Chinese media reported.
Scandals are proliferating, in part, because producers operate in a cutthroat environment in which illegal additives are everywhere and cost-effective. Manufacturers calculate correctly that the odds of profiting from unsafe practices far exceed the odds of getting caught, experts say."
