Levels of lead in rice imported into the United States (US) ranged from 6-12 mg/kg. For adults, the daily exposure levels from eating imported rice are 20-40 times higher than the Food and Drug Administration’s accepted levels. For infants and children, the daily exposure levels are 30-60 times higher. Lead is a neurotoxin that can damage the brain, and in young children whose brains are still growing, it can seriously diminish their capacity to learn and develop. It can disrupt children’s behavior, such as make them more aggressive, impulsive, and hyperactive. Lead increases blood pressure and causes cardiovascular diseases in adults.
