Green Peas/Soybeans
Snow peas and soybeans are commonly sold in China as green peas and soybeans covered with deadly sodium metabisulfite and food coloring. Food inspectors discovered thousands of cans of bogus, artificially colored peas during a 2005 inquiry.
Cabbage
Chinese farmers spray cabbage with a formalin solution that is extremely detrimental to the environment to keep it looking fresh throughout the summer months. Because of its toxicity, it is best to avoid this substance entirely.
