DETROIT (WWJ) – A Michigan man who once worked on the Soo Locks is suing his former employers, alleging that he suffered a debilitating illness from on the job exposure to pigeon droppings. 

Fifty-four-year old Bruce Harrison worked for the Grand Trunk Western Railroad Co. and Canadian National/Illinois Central Railroad. 

He says they failed to protect him from hazardous work conditions.

Harrison says eventually, he developed symptoms consistent with
histoplasmosis, a respiratory disease that can be spread by spores in bird droppings. 

He says he hasn’t been able to work for the past few years.
