October 24-30 is Childhood Lead Poisoning Prevention Week

October 24th through 30th is Childhood Lead Poisoning Prevention Week. Did you know that lead poisoning is dangerous for young children? Even small amounts of lead can harm a child’s health. A child with lead poisoning can have trouble learning, paying attention, and behaving. The only way to know if your child has lead poisoning is for your child to get a blood test for lead. Has your child been tested for lead poisoning?
