Zay is an epidemiologist in our Lead & Healthy Homes Program. She analyzes childhood lead exposure data and shares it with the public. The word "exposure" means being in contact with something. It's important to prevent childhood lead exposure because the health effects are irreversible and there are often no symptoms. A blood lead test is the only way to know if your child has been exposed to lead. health.state.mn.us/communities/environment/lead/prof/surv.html #HealthLiteracy #HealthLiteracyMonth
