An employee of NBC in New York has tested positive for anthrax, the TV network said today.
The FBI and the Centre for Disease Control are investigating.
The anthrax is not the same respiratory anthrax that killed a Florida man, NBC News said.
The employee tested positive for a cutaneous - skin - anthrax infection.
The employee, a woman who was not identified, has received treatment and is responding well, the network said.
NBC said the employee is in no danger and should recover fully.
The network said it had received some suspicious mail and immediately contacted the FBI, CDC and the New York Department of Health.
‘‘The mail was tested by these organisations, and the employee was treated by several physicians. All these tests came back negative,’’ said the NBC statement.
‘‘However, this morning, a later test on the employee came back positive for traces of cutaneous anthrax.’’
