Notice to Readers: Guidance on Initial Responses to Suspicious Letters and Packages

Law enforcement agencies and emergency responders are charged with investigation of suspicious letters and packages in the United States. Those responding are at risk from potential exposure to biologic agents, chemical substances, or radiologic materials. Guidelines for responding to five different types of situations (e.g., letter with unknown powder-like substance and threatening communication) have been developed by the Federal Bureau of Investigation, Department of Homeland Security, and Department of Health and Human Services/CDC. This guidance is now available at http://www.bt.cdc.gov/planning/pdf/suspicious-package-biothreat.pdf.
