Cabbage
Chinese farmers spray cabbage with a formalin solution that is extremely dangerous to the environment to keep it looking fresh during the summer months. Because of the toxicity of this substance, it is best to stay away from it entirely.
Sweet Potato Noodles
Sweet potato noodles were once thought to be safe, but that no longer holds true. Inspectors discovered that the product was made with industrial colors and paraffin wax after conducting an inquiry. A lot of businesses in Guandong Province have been closed.
