Text messages show former Milwaukee Health Commissioner Bevan Baker was warned about the need for secrecy in the city’s lead program. Major mistakes had been made and Baker was told there would be serious consequences if the public found out. Published reports in the Milwaukee Journal-Sentinel track the text messages between the commissioner and M-H-D nursing director Tiffany Barta last September. The agency had accidentally sent a lead-poisoned child from the hospital back to a home filled with lead hazards. The information didn’t go public for four months.
