In the wake of a Florida Center for Investigative Reporting/WUSF News investigation, the federal agency that monitors worker safety has revealed it is investigating the illness of a U.S. postal worker.
Former postal worker Jeffrey Lill says he became sick after coming into contact with a mysterious package from Yemen at an Orlando distribution facility.
He suffers from fatigue, tremors, and liver and neurological problems consistent with toxic exposure.
The Florida Center for Investigative Reporting, the Investigative Reporting Program at the University of California-Berkeley and WUSF News reported this week that Lill's problems began after he says he handled the leaking package in February 2011.
The U.S. Postal Service has denied the package ever existed.
A spokesman for the Occupational Safety and Health Administration confirmed Tuesday that the agency is looking into what made Lill sick.
OSHA spokesman Michael Wald says the probe could take anywhere from a few weeks to a few months.
