Postmaster General Jack Potter said yesterday that the U.S. Postal Service will conduct a postcard mailing to all U.S. households and businesses, advising them on how to protect themselves against contaminated mail.
Potter and FBI Director Robert Mueller also announced a $1 million reward for information leading to the arrest and conviction of the Anthrax mailers. The mailing will go to all 147 million addresses in the U.S.
The news came as Americans braced themselves for more bio-terrorism.
In one development, a Trenton, NJ postal worker who may have handled some of the contaminated mail was diagnosed with skin anthrax.
In Tokyo, nine letters, including a mail order book shipment from the U.S. with powder on it were examined, but were found not to contain anthrax.
The USPS has advised mail recipients to be suspicious if a letter has a powdery substance on the outside, or is from an unfamiliar person. It has also cautioned them against letters that have no return address, or are marked with words such as “personal” or “confidential.”
