An MTA bridge and tunnel officer was stricken with Legionnaires’ Disease last week, according to his union.

The 14-year veteran highway patrol officer went to the ER at Long Island Jewish Hospital on Aug. 5 and was diagnosed with Legionella pneumonia, said Wayne Joseph, president of the Bridge and Tunnel Officers Benevolent Association.

The employee, based out of the Staten Island administrative office near the Verrazano-Narrows Bridge, was treated and released after his health improved.

MTA officials cordoned off three shower stalls with yellow hazard tape at its VN facility on Staten Island as a precautionary measure, Joeph said.

“Please be advised that until further notice, the showers in this area are not to be used. I apologize for any inconvenience,” Renee Shepherd, director of MTA Bridges South, said in a memo.

The city last month grappled with a Legionnaires’ outbreak in Washington Heights, killing one and sickening 27 residents.

Joseph said it’s unclear where or how the officer contracted Legionnaires, but said he had not patrolled or been in Washington Heights.

He said another lieutenant and a maintenance worker were told not to go back to work after seeing the doctor, because they were exhibiting Legionnaires’ symptoms of high fever, chills and coughing.

Joseph also said a group of sergeants and lieutenants is awaiting tests for Legionnaires’.

The city Health Department and MTA had no immediate comment.
