Occupational and Take-home Lead Exposure Among Lead Oxide Manufacturing Employees, North Carolina, 2016

Objective: In 2016, North Carolina blood lead level (BLL) surveillance activities identified elevated BLLs among 3 children exposed to take-home lead by household members employed at a lead oxide manufacturing facility. We characterized BLLs among employees and associated children and identified risk factors for occupational and take-home lead exposure. Methods: We reviewed BLL surveillance data for 2012-2016 to identify facility employees and associated children. We considered a BLL ≥5 μg/dL elevated for adults and children and compared adult BLLs with regulatory limits and recommended health-based thresholds. We also conducted an environmental investigation and interviewed current employees about exposure controls and cleanup procedures. Results: During 2012-2016, 5 children associated with facility employees had a confirmed BLL ≥5 μg/dL. Among 77 people employed during 2012-2016, median BLLs increased from 22 μg/dL (range, 4-45 μg/dL) in 2012 to 37 μg/dL (range, 16-54 μg/dL) in 2016. All employee BLLs were
