The Wisconsin Department of Health Services (DHS) recently reported that the number of children under age six screened for lead exposure increased by 26 percent statewide last year. While the statewide improvement is encouraging, Door County families still need to be aware of potential lead hazards.
"There is no safe level of lead," warns Katie Van Laanen, a public health nurse with Door County Public Health. In 2024 in Door County alone, nearly 15 percent of children tested through Women Infants and Children (WIC) showed elevated levels of lead. A result of 3.5 micrograms per deciliter or higher is considered elevated.
Despite the fact that lead-based paint was banned by the federal government in 1978, old paint remains the primary source for lead exposure in children. However, the public should also be aware of other potential hazards for lead exposure. Children can be exposed to lead from toys, car batteries, lead sinkers used by charter fishermen, and even debris or dust that parents may bring home on their clothes from work.
"Lead exposure is so harmful because it affects the nervous systems," Van Laanen explains. "It makes it hard for children to learn, think, and grow. The reason it's more of a concern for children under age six is because of their normal childhood behaviors. They learn by putting everything in their mouth, touching everything, which is a normal stage of development, but also puts kids at risk."
Early testing and prevention are key to protect children from the hazards of lead exposure. All children are recommended to receive a blood lead test at ages one and two. Landlords and property owners can take action by inspecting their properties for peeling paint, having their drinking water tested, and hiring a professional to test for lead every one to three years.
The Wisconsin Lead-Safe Homes Program (LSHP) provides assistance to ensure children have a safe home environment, free from lead contamination. Pregnant women who are enrolled in Medicaid or BadgerCare Plus may be eligible for help with home renovations or abatement services.
