Kane Co. Health Officials Urges Parents To Test Children For Lead Exposure

KANE COUNTY, IL — The Kane County Health Department is reminding parents about new Illinois requirements for childhood lead testing and encouraging families to take precautions against exposure ahead of National Lead Poisoning Prevention Week, Oct. 25-31.

Under a state law that took effect July 1, 2026, all children must receive blood lead testing at approximately 12 and 24 months of age. Children ages 6 and younger must also be assessed for lead exposure risks during routine medical visits, with additional testing as needed. Health officials say lead poisoning remains a serious concern, particularly for young children, because even low levels of exposure can affect brain development, learning, behavior and growth.

Children with elevated blood lead levels often show no obvious symptoms, making routine testing essential for early detection, according to the health department.

"Every child deserves a healthy start in life, and preventing lead exposure is an important part of protecting their future," said Michael Isaacson, executive director of the Kane County Health Department. "We want families to understand where lead may be found, how to reduce exposure and why blood lead testing is so important."

Lead exposure can occur through deteriorating lead-based paint and dust, particularly in homes built before 1978, as well as contaminated soil and certain plumbing materials.

Some imported pottery, dishes, spices, cosmetics and toys may also contain lead. Construction, renovation and hobbies involving ammunition or stained glass can introduce lead dust into homes, health officials said.

To reduce exposure, the health department recommends that families regularly wash children's hands and toys, clean floors and windowsills using wet cleaning methods, and keep children away from peeling paint and renovation areas in older homes.

Residents should also use lead-safe practices when renovating homes built before 1978 and use only cold tap water for drinking, cooking and preparing infant formula.

The health department will offer free lead testing for holiday serving dishes during its Safe Home for the Holidays event from 4 to 6 p.m. Nov. 5 at its Aurora office, 1240 N. Highland Ave. No registration is required.

The department's Childhood Lead Poisoning Prevention Program also provides education, follow-up services and connections to resources for families of children with elevated blood lead levels.
