The New Jersey Department of Health and Senior Services has announced that a trace of anthrax was found inside a letter carrier case at the Palmer Square post office in the heart of Princeton Borough. The area where the anthrax was found was cleaned early Saturday before the post office opened.
Palmer Square was one of about 50 local post offices that were tested for anthrax because their mail is sorted at the Hamilton mail processing facility, where postal workers have contracted the inhalation form of the disease. Palmer Square was among four post offices that had one trace of anthrax each, while a fifth post office had an ambiguous test result. No anthrax was found in any of the other offices tested.
At the Hamilton facility, on the other hand, swabs in 34 separate locations tested positive for anthrax, according to state health department spokesman Dennis McGowan.
Because the amount of anthrax found in the Palmer Square building is so small, state officials have determined that the risk of postal workers developing the disease is extremely low.
State Epidemiologist Eddy Bresnitz said in a press release that none of the workers at the four offices with positive test results have come down with the illness.
According to state health officials, the positive reading is most likely the result of cross-contamination with mail from the Hamilton facility.
They said that there is no need to close these post offices in response to the anthrax finding.
