The Centers for Disease Control and Prevention's website has a very eerie warning regarding anthrax.

On the CDC's website it warns that "If a bioterrorist attack were to happen, Bacillus anthracis, the bacteria that causes anthrax, would be one of the biological agents most likely to be used."

The CDC's warning continues "Anthrax makes a good weapon because it can be released quietly and without anyone knowing. The microscopic spores could be put into powders, sprays, food, and water. Because they are so small, you may not be able to see, smell, or taste them."
