Suspicious Packages

Guidelines for the Proper Handling of Suspicious Packages

Letters containing Bacillus anthracis (anthrax) have been received by mail in several areas in 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.

Anthrax organisms can cause infection in the skin, gastrointestinal system or the lungs. To do so the organism must be rubbed into abraded skin, swallowed or inhaled as a fine, aerosolized mist. Disease can be prevented after exposure to the anthrax spores by early treatment with the appropriate antibiotics. Anthrax is not contagious (not spread from one person to another person).

For anthrax to be effective as a covert agent, it must be aerosolized into very small particles. This is difficult to do and requires a great deal of technical skill and special equipment. If these small particles are inhaled, life-threatening lung infection can occur but prompt recognition and treatment are effective.

Identifying Suspicious Packages & Envelopes

If a package or envelope appears suspicious, do not open it! There are some notable characteristics of suspicious packages and envelopes.

Inappropriate or Unusual Labeling

  • Excessive postage
  • Handwritten or poorly typed addresses
  • Incorrect titles or title without a name
  • Marked with any threatening language
  • Marked with restrictions such as "Personal," "Confidential" or "Do not x-ray"
  • Misspellings of common words
  • Not addressed to a specific person
  • Postmarked from a city or state that does not match the return address
  • Strange return address or no return address


  • Excessive packaging material such as masking tape, string, etc.
  • Lopsided or uneven envelope
  • Oily stains, discolorations or odor
  • Powdery substance felt through or appearing on the package or envelope

Other Suspicious Signs

  • Excessive weight
  • Protruding wires or aluminum foil
  • Ticking sound

Handling of Suspicious Packages & Envelopes

  • Alert others in the area about the suspicious package or envelope. Leave the area, close any doors and take actions to prevent others from entering the area. If possible, shut off the ventilation system.
  • Do not carry the package or envelope, show it to others or allow others to examine it.
  • Do not shake or empty the contents of any suspicious package or envelope.
  • If at work, notify a supervisor, security officer or emergency officials. If at home, call your local non-emergency number and the proper officials will be dispatched. Try to avoid tying up 911 lines unless you have an immediate emergency.
  • If possible, create a list of persons who were in the room or area when this suspicious letter or package was recognized and a list of persons who also may have handled this package or lefter. Give this list to both the local public health authorities and law enforcement officials.
  • Put the package or envelope down on a stable surface; do not sniff, touch, taste or look closely at it or at any contents which may have spilled.
  • Wash hands with soap and water to prevent spreading potentially infectious material to face or skin. Seek additional instructions for exposed or potentially exposed persons (resources listed on reverse side).
