Personally, I would not worry too much about it. People getting scared and panicking helps no one but the terrorists. Right now it looks like all these scares are by mail delivered to businesses or individuals. The two common threads are mail and a white powder or residue. If you have any suspicious mail, don't open it, and call the authorities if it makes you feel better. Most of us have some idea of the mail we get on a daily basis, and if something doesn't look right, you should be able to pick up on it. Anthrax is a germ, it just has more dire consequences if you allow it to take hold and develop. Wash your hands, use a good anti-bacterial soap, and you should be OK. In these trying times you have to use your brain. Stay aware of your surroundings and your life. If you do not and give in to the fear that these terrorists are spreading, then they have already won. Of course, once they start screwing with the water supply, that is something else.
