The Schedule enables the HSC to approve and publish a document Categorization of Biological Agents According to Hazard and Categories of Containment containing a list of They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious medical conditions—even death. The top two categories are: Category A agents. Categories B and C Agents •Cat B Agents –Moderately easy to disseminate –Moderate morbidity, low mortality –Require enhancement of current diagnostic/laboratory capabilities and enhanced surveillance •Cat C Agents –Emerging pathogens thought to have potential. Sulfur mustard (H) (mustard gas) Lewisites/chloroarsine agents. A biological weapon is generally composed of a biological agent or toxin (bacteria, mycoplasma, rickettsiae, viruses, yeasts, fungi), additives to assist with dissemination and stability, and a delivery system. fungi. The categorization is based on the degree of the respective biological agents’ infection risk. CBRN Types Category B c. Category C.

Biological Diseases/Agents. Does the biological commodity contain infectious pathogens as defined and categorized above? Score 1 User: Which category of biological agents includes agents that have some potential for dissemination as well as agents of concern for food and water safety? Biological Substances Category B. Category B substances are infectious substances which do not meet the criteria for inclusion in Category A. These shipments must follow Packing Instructions 650. Biological material that would be shipped in this category includes: Adenovirus (replication competent). Often, diseases caused by bacteria are carried by animals which transmit the disease to man. Select agents are biological agents and toxins that have been determined to have the potential to pose a severe threat to public health and safety, to animal and plant health, or to animal or plant products. parasites. Biological agents are assigned to four risk groups to enable employers to implement practical protective measures.
