Preventing Lead Poisoning

Primary prevention of lead poisoning is 100% doable. It can be accomplished by eliminating lead hazards before children are exposed.

Wisconsin encourages parents to check their home for lead hazards, especially for chipping and peeling lead-based paint in homes built before 1978, and maintain their home in a lead-safe condition.

What Parents Can Do

Prevention and intervention

Preventing lead exposure is so critical because there is no safe level of lead in the human body. Check your home for chipping and peeling lead-based paint and other lead hazards and maintain your home in a lead-safe condition to protect your family from exposure to lead hazards. More detailed information can be found on the Check and Maintain Your Home page and the What Homeowners Can Do tab on this page.

Regular well-balanced meals are important for adequate growth and development in all children.

Children who do not have enough iron in their body may absorb lead more easily. An age-appropriate diet that includes the recommended amount of iron can help the body avoid absorbing lead. However, research shows that taking iron supplements does not help lower blood lead levels.

Families of children with lead poisoning that are income eligible can receive nutritional support from WIC, especially to get iron from food.

What Homeowners Can Do

Common renovation, repair, and painting activities that disturb lead-based paint (like sanding, cutting, replacing windows, and more) can create hazardous lead dust and chips which can be harmful to adults and children. Home repairs that create even a small amount of lead dust are enough to poison your child and put your family at risk.
