Biosecurity is a set of preventive measures designed to reduce the risk of intentional removal (theft) of a valuable biological material. These preventative measures are a combination of systems and practices usually put into place at a legitimate bioscience laboratory that could be sources of pathogens and toxins for malicious use. Although security is usually thought of in terms of "Guards, Gates, and Guns", biosecurity encompasses much more than that and requires the cooperation of scientists, technicians, policy makers, security engineers, and law enforcement officials.

Components of a laboratory biosecurity program include:

  • Physical security
  • Personnel security
  • Material control & accountability
  • Transport security
  • Information security
  • Program management

Challenges in Biosecurity

[編集]

The destruction of the World Trade Center in Manhattan on September 11, 2001 by terrorists, and subsequent wave of anthrax attacks on U.S. media and government outlets (both real and hoax), led to increased attention on the risk of bioterror attacks in the United States. Proposals for serious structural reforms, national and/or regional border controls, and a single co-ordinated system of biohazard response abounded.

The proliferation of high biosafety level laboratories around the world has many experts worried about availability of targets for those that might interested in stealing dangerous pathogens. Emerging and Re-emerging disease is also a serious biosecurity concern. The recent growth in containment laboratories is often in response to emerging diseases, many new containment lab's main focus is to find ways to control these diseases. By strengthening national disease surveillance, prevention, control and response systems, these labs are raising international public health to new heights.

UNU/IAS Research into Biosecurity & Biosafety emphasizes "long-term consequences of the development and use of biotechnology" and need for "an honest broker to create avenues and forums to unlock the impasses."

Agents of Concern

[編集]

The following agents are deemed a biosecurity concern by the US Government through the US Select Agent List. The list is divided between agents that can infect only humans, zoonotic agents (which can infect both humans and animals), agents that can only infect animals, and agents that can infect only plants.

Human Agents
