Lead Poisoning Prevention
Lead poisoning is a serious, but preventable, public health problem that can result in long-lasting neurological damage to young children. Lead poisoning is defined as a blood lead level greater than or equal to 10 µg/dL of whole blood.
Most cases remain undiagnosed and untreated because low blood lead levels are not often associated with overt symptoms. However, blood lead levels as low as 10 µg/dL can adversely affect intelligence, learning, behavior, and development. At extremely high levels (45 µg/dL or higher), lead poisoning can cause seizures, coma, and even death in children.
Great advances have been made in reducing lead exposure during the past 20 years. Lead is no longer present in gasoline, new supplies of house paint, or cans used for food or beverages. Lead also has been reduced in industrial emissions, drinking water, hazardous waste and consumer goods.
As a result, there has been a decline of more than 80 percent in children's blood lead levels since the mid 1970s. In 1978, roughly 14.8 million children in the United States suffered from lead poisoning. By the late 1990s, that number had declined to 434,000 (2.2%) children, according to estimates of the Centers for Disease Control (CDC). The Department of Health and Human Services' Healthy People 2020 initiative has set a national goal of reducing mean blood lead levels in children to 1.4 µg/dL by 2020.

- Lead based paint
- Lead contaminated dust, soil, and water

Healthy Homes and LeadPoisoning Prevention Program (CLPPP)
The Miami-Dade County Health Department has received approximately 250 reports of elevated blood lead levels annually from 2000 to 2011. One of the most important objectives of the CDC funded program, since its inception in 1999, has been to increase primary prevention activities and lead screening among children at high risk to lead poisoning. In following and modifying the CDC recommendations for targeted screening of children for lead poisoning, the Miami-Dade County Healthy Homes and Lead Poisoning Prevention Program CLPPP has issued screening guidelines for primary care physicians.
The program works on the Healthy Homes initiative to raise awareness of environmental health risks in homes such as lead-based paint, mold, carbon monoxide, pesticides, and hazardous household products through one-on-one family education, realtor and landlord education. To reduce or eliminate environmental hazards in the home, the program refers families to local health and housing programs to fix their hazards.
CLPPP Program activities include:
- Case management
- Environmental investigations
- Policy development
- Community Outreach Education and Training
Case management services (10 µg Pb/dL):
- Risk Assessment Questionnaire
- Assess exposure
- Identify at-risk siblings and playmates
- Lead poisoning prevention

- Facilitate medical care access
- Inform provider of follow-up recommendations
- Refer to WIC, Healthy Start, Children’s Medical Services and other social services
- Environmental Investigations
- Home Investigations
- BLL’s greater than or equal to 20 µg Pb/dL
- BLL’s persistently greater than or equal to 15 µg Pb/dL
- Increase in BLL
- More than one lead poisoned child in home
