A postal service official, who declined to give his name, confirmed to CNN that "small traces were detected with minimal surface contamination" were found in four facilities. The discovery, the official said, "should have not much impact at all on the operations of these four facilities."

"They're going to be cleaned up under the guidance of the Department of Health and the CDC," said the official, adding that the facilities will remain open.

The official confirmed anthrax at two of the facilities -- the Palmer Square Station in Princeton and the Rocky Hill main office in Rocky Hill.

These facilities are new locations in addition to sites where anthrax has already been found. The most significant discovery of anthrax was at the Trenton regional processing plant in Hamilton Township, where three anthrax-tainted letters were postmarked and sent to a U.S. senator and two New York media outlets.

The Health Department said it would release additional details later in the day.

Meanwhile, The State Department mail facility worker who was hospitalized with inhalation anthrax is heading home.

Winchester (Virginia) Medical Center spokesman Wes Williams said the man who came down with inhalation anthrax was to be released Friday afternoon.

The unidentified man worked at a Sterling, Virginia, mail facility that handles mail for the State Department. He was admitted to the Winchester Medical Center October 25.
