Lead Information for Parents

Lead poisoning is a serious threat to children’s health, but it’s preventable — and Maryland has strong laws to protect families. Even small amounts of lead can affect a child’s development, behavior, and overall well-being.

The state offers free lead testing for all Medicaid-enrolled children and for any child born on or after January 1, 2015. Testing is especially important between 6 months and 6 years of age, when children are most vulnerable.

Children should be tested at 12 and 24 months, or as advised by a healthcare provider. Additional testing may be needed if a child shows symptoms, lives in or visits older homes with peeling paint, or is exposed to lead through an adult’s work.

Ask your pediatrician about blood lead testing or contact your local health department. Any capillary test result of 5 micrograms per deciliter (mcg/dL) or higher must be confirmed with a venous test. If lead levels are elevated, the health department will help identify the source and provide support.

As of 2023, Maryland follows the federal intervention threshold of 3.5 micrograms per deciliter. More than 3,000 children in the state were identified at or above this level, triggering investigations and potential enforcement to reduce risks.

Where Lead Can Be Found

Homes built before 1978 often have lead-based paint, which can chip or create dust that’s dangerous if breathed or swallowed.
Soil, plumbing, and even some toys or imported goods may also contain lead.

Maryland’s Laws and Protections

Rental Properties: Maryland requires landlords of pre-1978 rental homes to meet strict lead safety standards. They must register properties with the state, perform annual inspections, and fix any lead hazards.
Childhood Testing: Maryland law requires doctors to test all children at 12 and 24 months old for lead exposure — even if they appear healthy.
Renovations: Contractors working on older homes must be certified and follow safe work practices to avoid spreading lead dust.

How to Protect Your Children

Test Your Home: If your home was built before 1978, have it inspected by a certified lead professional.
Practice Lead-Safe Habits: Regularly clean floors, windowsills, and hands to remove dust. Use cold tap water for drinking and cooking (hot water can carry more lead).
Get Your Child Tested: Even if you don't think your child has been exposed, follow the state’s testing schedule. Early detection can prevent serious harm.
Be Cautious with Renovations: Hire certified contractors when repairing or remodeling older homes.
