National Lead Poisoning Prevention Week is October 25–31, 2026. This year’s theme is “Keep Kids Safe from Lead.” The CDC frames the week around three simple ideas: get the facts, get your child tested, and get your home tested [1].
Lead can quietly harm a growing child. The CDC says no safe blood lead level in children has been found. Even low levels have been shown to affect learning, attention, and how well kids do in school [2]. The hard part is that most children with lead in their blood have no obvious symptoms [2]. A child can look and act healthy and still have had exposure.
That can feel scary. But families can prevent lead exposure, and there are clear steps any family can take [3]. This lead poisoning prevention guide covers where lead comes from, when to ask about a test, and everyday habits that help.
Why young children are most at risk
Children younger than 6 are most at risk. Their bodies are still developing, and they often put their hands, toys, and other objects in their mouths [1]. Picture a toddler crawling on a dusty floor near an old window, then sucking a thumb. That child can swallow tiny bits of lead dust without anyone noticing.
The CDC notes links between even small amounts of lead and delayed growth and development. The CDC also notes links to learning problems and hearing, speech, and behavior problems [1]. That is why finding and removing lead early matters so much.
Know where lead can come from
The most common source is old paint. Homes built before 1978, when lead-based paint was banned for homes, probably have lead paint somewhere. When that paint peels or cracks, it can turn into dust that children swallow or breathe in [2]. Repairs or remodeling in older homes can also stir up lead dust [1].
Lead can also be in soil and in drinking water that flows through lead pipes or fixtures [1]. Some products can contain lead too, including certain toys, cosmetics, spices, traditional home remedies, imported candies, and imported pottery [1] [2]. The EPA adds that food or drinks stored or served in lead crystal or lead-glazed pottery can become contaminated [4]. Old hand-me-down toys and painted furniture are also worth a second look [4].
Finally, lead can come home on clothes and shoes. Some jobs and hobbies, such as stained glass work, use lead-based products [2].
Ask about a blood lead test
A blood test is the best way to find out if a child has been exposed to lead [3]. Children enrolled in Medicaid must be tested at ages 12 and 24 months. Children ages 2 to 6 with Medicaid who have no record of a test must also be tested [3].
For other children, testing depends on risk. The CDC lists several groups of children at higher risk. These include children who live in or spend time in a building built before 1978 and those from low-income households. Children who are immigrants or refugees or were recently adopted from less developed countries are also at higher risk. The same goes for kids who spend time with someone who works with lead [3]. Think about grandparents’ homes and child care too, not just where your child sleeps.
Health care providers and most local health departments can do the test. Medicaid covers testing for enrolled children, and many private insurance plans cover it too [3]. Ask your plan to be sure. A test often starts with a finger or heel prick. If that result shows lead, a blood draw from a vein may be done to confirm it [3].
These questions can help at your child’s next visit:
- “Does my child need a lead test, based on our home and family?”
- “Has my child been tested before? What was the result?”
- “What should we do if the level is high?”
If a test does find lead, your child’s clinician will talk with you about next steps. These can include finding and removing the lead source, food choices, and repeat testing [3].
Lead poisoning prevention at home: lower lead dust
Small lead poisoning prevention habits can make a real difference. The EPA suggests cleaning often with a wet mop, wet cloth, or wet paper towel. This helps reduce paint chips and dust [4]. Pay special attention to windowsills and floors where children play.
Wash hands with soap and water several times a day, especially after playing or working outside [4]. Help young children wash before meals, naps, and snacks. Take shoes off at the door, and use doormats inside and outside. That keeps people from tracking in lead dust and soil [4].
Do you work with lead or have a hobby that uses it? Then wash up and change your clothes before you go home, and wash work clothes separately [4].
Tru-Tips: Make a “wet wipe-down” part of your weekly routine. Pick one day to wipe windowsills, window wells, and floors where your child plays. Use a damp paper towel, then throw it away.
Check repairs and water
Was your home built before 1978? Talk with a certified lead professional before any repair, remodel, or painting job. And hire a lead-safe certified renovator [4]. The CDC advises against removing lead paint yourself [1]. Scraping or sanding can create a lot of dust very fast.
For water, you can read your local water quality report to see lead results. To find out if your home has a lead service line, contact your water utility or a licensed plumber [4].
If you rent, you have a voice too. Landlords and sellers of homes built before 1978 must tell you about known lead paint hazards [1]. You can say: “Our home was built before 1978. Do you know of any lead paint, and how will repairs be done safely?”
Let’s talk about it
Has your child had a lead test? If you live in an older home, what is one habit that helps your family keep dust down? Your tip could help another parent this week.
One Tru Step: At your child’s next visit, ask one question: “Does my child need a lead test?” Write the answer down.
