Annual Reports of Childhood Lead Poisoning in Wisconsin

These annual reports for Wisconsin comprise local health department jurisdiction and statewide totals and rates of the number of children tested for lead and found to be lead poisoned. From 1991 - 2011, the Centers for Disease Control and Prevention (CDC) defined lead poisoning as a blood lead level (BLL) of 10 micrograms per deciliter (mcg/dL) or greater and recommended public health intervention for those children. According to Wisconsin Statute, a child with a BLL of 20 mcg/dL or greater represents a "case" and requires public health intervention. Thus, the reports also include the number of cases of children with extremely high levels of lead by health department jurisdiction.

In 2012, CDC lowered the reference level for intervention from 10 mcg/dL to 5 mcg/dL, increasing the number of children under age 6 exposed to lead in Wisconsin by a factor of five. The data report for 2011 - 2013 is in a different format from previous years. In addition to the number of children at 10 mcg/dL or greater, it includes the number and rate (percent) of children with BLLs between 5 and 9 mcg/dL. Also included is a time trend for the state of the number of children tested for lead from 2001 - 2013 and a time trend for those found to be lead poisoned in that same time frame.
