Mineola, N.Y. (AP) — New York's governor says questions about the environmental condition of Plum Island need further study before the federal government proceeds with its sale.

The island off eastern Long Island is home to the nation's only laboratory that studies infectious diseases that could imperil the nation's livestock industry.

Congress has approved a plan to move the lab to a new facility in Manhattan, Kansas, and sell the island to defray the costs.

Elected officials in both New York and Connecticut oppose the sale.

New York Gov. Andrew Cuomo said Monday that state environmental officials have questions about the condition of the island. He says those issues need to be addressed before a sale proceeds.

The General Services Administration is overseeing the sale. A spokesman there did not immediately comment.
