The latest incident was made public when a replacement worker notified members of Senator Clinton's staff of the power failure. In an interview, the worker, who insisted on anonymity, said, ''The reason I am coming forward is because what I have seen at the center is really out of hand and something needs to be done about it.'' Requests by The New York Times to visit the island have been rejected.
The power failure is the first time the possibility of a leak of the pathogens studied on the island has been raised.
