The Illinois Department of Public Health has added 148 new ZIP codes to its high-risk list for lead exposure, increasing mandatory testing for children. This brings the total to almost 1,200 high-risk ZIP codes across 60 Illinois counties.
“There is no safe level of lead in the blood,” IDPH Director Dr. Sameer Vohra said in a news release from the department. “To better serve our children and build brighter futures for all of our residents, [the] IDPH is acting to ensure that more children have access to the testing and interventions necessary to decrease the potential serious physical and developmental health concerns linked to lead exposure.”
Under Illinois law, children in high-risk ZIP codes must be tested for lead exposure at 12, 24 and 36 months. All children 6 and younger are assessed using a questionnaire, and those in other risk categories also are tested, according to the release.
High-risk ZIP codes in Illinois are determined by an algorithm assessing various risk factors. The list is gradually expanding, with plans for universal lead exposure testing statewide by 2026, according to the release.
In Illinois, blood tests showing lead levels above five micrograms per deciliter (µg/dL) require public health intervention, including a home inspection to identify and remove lead sources and a visit from a public health nurse to educate the family on protecting children from lead exposure, according to the release.
