Stringent protocols and engineering are used to contain the most dangerous pathogens, therefore these facilities are often referred to as high-containment laboratories. High-containment laboratories play a critical role in the biodefense effort, offering the hope of better responses to a biological attack and a better understanding of the bioterrorism threat. However, they could also increase the risk of a biological attack by being a source of materials or training. This book examines the biosafety and biosecurity issues in high-containment laboratories across the United States.
