Bagged Iceberg Lettuce Is Washed With Chlorine
Health experts warn that bagged iceberg lettuce have been doused in unhealthy levels of chlorine. Chlorine is very dangerous because when it enters the body as a result of swallowing, breathing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact, according to sources.
