No Symptoms

The Postal Service is reassuring employees in this area and Memphis that they are not in danger from two letters laced with ricin. It says the substance was not in a form that would pose a risk. No employee has reported symptoms such as a fever or cough. Those usually appear within 24 hours of inhaling the poison. Postal employees at all facilities received briefings yesterday. A postal union complained earlier this week that the agency had not given employees sufficient warning of the potential dangers.
