    • Yearly appropriated funding levels for CDC Childhood Lead Poisoning Prevention Program (CLPPP) averaged $36 million through the mid-2000s. CDC recommended targeted screening and focused on improving surveillance.

    • A total ban on food cans with lead solder, including imported cans, became effective.
    • CDC collaborated with the Council of State and Territorial Epidemiologists (CSTE) to develop a national surveillance system for monitoring blood lead levels (BLLs) in the United States, and reporting of BLLs became the first noninfectious condition to be notifiable at the national level.
    • CDC CLPPP began collecting blood lead surveillance data on children younger than 16 years from state health departments. Awarded $29 million in extramural awards.

    • The Centers for Medicare and Medicaid Services (CMS) adopted CDC’s universal screening requirements for children receiving Medicaid benefits.

    • Title X of the Housing and Community Development Act (Residential Lead-Paint Hazard Reduction Act) expanded lead-based hazards to include lead-contaminated dust and soil and shifted response to a preventative strategy.

    • The Department of Health and Human Services (HHS) released the Strategic Plan for the Elimination of Childhood Lead Poisoning that set forth a comprehensive agenda to eliminate childhood lead poisoning.
    • CDC began promoting primary prevention activities, such as community-wide environmental interventions and education and nutritional campaigns, to lower children’s BLLs to <10 µg/dL.
    • The Environmental Protection Agency (EPA) published the Lead and Copper Rule to minimize lead and copper in drinking water and established a maximum contaminant level goal (MCLG) of zero for lead.
    • CDC recommended screening by blood lead testing for virtually all children aged 1 to 5 years and that all children younger than 2 years be screened at least once.

    • CDC’s “blood lead level of concern” was defined as children with BLLs ≥ 10 µg/dL.

    • CDC CLPPP received full funding which supported a comprehensive program that recommended universal screening and provided guidance on case management.
