In China, eggs are sold by weight and their sale is often unregulated, particularly at local markets and in
areas where the customers by large quantities at a time. Unscrupulous vendors have been known to pass off fake eggs to their
unsuspecting buyers.
There are three types of faked eggs. The first are empty or cracked shells that are filled with soil. Since the eggs are sold by weight, a few soil-filled eggs in a crate will make it heavier and go unnoticed until it is too late. The second type of fake egg is the red-yolk egg. Because the redder yolks are considered to be more valuable and of higher quality, some egg-sellers feed their chickens very high quantities of food dyes, which causes them to produce red yolks without an increase in the quality of the egg or in the lifestyle of the chicken.
The most disturbing - though some might say disgusting - faked egg is the man-made egg.
