Conceptual Framework for Biosecurity Levels   [open pdf - 2MB]

"This presentation provides an outline of how to secure certain pathogens and toxins. The aim of biosecurity is to mitigate biological weapons threats at the source, but biosecurity only addresses a small part of the BW threat. The research community needs specific tools to achieve a balance between adequately protecting certain pathogens and toxins and not jeopardizing research on those agents and toxins. Biosafety aims to reduce or eliminate accidental exposure to or release of hazardous agents through four biosafety levels. Biosafety is now considered standard microbiological practice around the world. The need to appreciate the risk of bioterrorism will always exist. Not every asset can be protected against every conceivable threat, thus a risk management approach needs to be employed. Not all pathogens and toxins need the same level of protection. Agents should be placed in a biosecurity level based upon their risk of theft and use as a biological weapon. Biological agent risk levels are divided into the following: nonpathogenic, low risk pathogens and toxins (LRPT), moderate risk pathogens and toxins (MRPT), high risk pathogens and toxins (HRPT), and extreme risk pathogens and toxins (ERPT). The biological agent Coccidioides immitis is used as an example of a low risk pathogen with minimal weaponization potential."
