  • Lead poisoning is caused by swallowing or breathing lead.
  • Children under 6 years old are most at risk.
  • Most children get lead poisoning from paint dust in homes built before 1978.
  • Lead poisoning can cause learning disabilities and behavior problems.
  • A lead test is the only way to know if a child has lead poisoning.

How Lead Affects the Body

Even if there are no clear signs of lead poisoning, lead still affects the body. Even low levels of lead in the blood of children can result in:

  • Behavior problems and hyperactivity
  • Lower IQ and learning problems
  • Slowed growth
  • Hearing problems
  • Anemia

How Lead Poisoning Happens

The most common cause of lead poisoning is when children play near areas with worn out or damaged paint. They can get invisible lead dust on their hands and toys. Then, when they put their hands or toys in their mouth, they can get lead poisoning.

Lead in Your Home

Lead is often found in:

  • Paint and varnish in homes built before 1978, especially if it is peeling or chipping.
  • Drinking water when lead pipes or solder are present.
  • Dirt, hobby areas and workplaces, varnishes on antiques, old painted toys and pottery.
  • Leafy vegetables grown in contaminated soil or chicken eggs from chickens that ate lead contaminated materials.
  • Certain imported candies, ceramic dishes, and folk remedies may also be contaminated with lead.

Lead in Your Community

Children may also be exposed to lead outside their home. Childcare facilities, schools, and homes of friends or family are places that also may have lead hazards. Talk to your childcare provider or school staff to find out what is known about lead in these facilities. 

Here are recommendations that we have made to schools and childcare centers about the potential for lead in drinking water: 


Protect Your Child From Lead

Anyone can get lead poisoning, but children between six months and six years of age are at highest risk.

Things that put small children at risk for lead poisoning:

  • They put their fingers and toys in their mouths a lot.
  • They play on the ground and floor where paint chips and lead dust may have fallen.
  • They chew and put their mouth on painted window sills, furniture, and railings.
  • They eat dirt and paint chips.

Signs of lead poisoning

Often there are no signs. Your child can have lead poisoning and not look or act sick. The only way to know is to have a blood test done.


Take Precautions

Children under 6 years of age living in or visiting pre-1978 housing are at greatest risk for lead poisoning. These basic steps can help prevent a child from becoming lead poisoned or being exposed to lead:

  • Wash floors and windows the right way.
  • Wash your child's hands often, especially before eating and sleeping.
  • Cover chipped or peeling paint with contact paper, duct tape, or a new layer of paint.
  • Do not power sand lead-based paint, even hand sanding should be avoided.
  • Eat healthful foods high in iron, calcium, and vitamin C; avoid fatty foods.
  • Use cold tap water for drinking, cooking, and making infant formula.
