Section 17 - How to Recognize and Handle Suspicious Packages or Envelopes

Letters containing Bacillus anthracis (anthrax) have been received by mail in several areas of the United States.  In some instances, anthrax exposures have occurred, with several persons becoming infected.  To prevent such exposures and subsequent infection, all persons should learn how to recognize a suspicious package or envelope and take appropriate steps to protect themselves and others.

Mail Handling

  • Handle mail in well-ventilated areas.
  • If possible chose an area to open mail that can be isolated should a suspicious package or envelope be found in the mail.
  • Avoid touching mouth, eyes, or face when handling mail. Use gloves while handling mail. 
  • Change gloves when they are grossly dirty or have perforations.  Remove gloves when eating, drinking, or smoking. 
  • Identifying Suspicious Packages and Envelopes 

Inappropriate or unusual labeling
