Introduction to Terrorism Against U.S. Agriculture:. Protecting Crops through Plant Biosecurity Management.
E N D
Introduction to Terrorism Against U.S. Agriculture: Protecting Crops through Plant Biosecurity Management This slide show was adapted from a December 2003 presentation by James Schoelz, Ph.D., at the Missouri Summit on AgroTerrorism. Schoelz is Professor and Chair of the Department of Plant Microbiology and Pathology at the University of Missouri-Columbia.
Presentation Overview Part 1: • Key Points about Terrorism against the U.S. • 5 categories of Weapons of Mass Destruction • Targeted Attacks against Agriculture Part 2: • What is Plant Biosecurity Management? • Pathogens attractive to terrorists • List of threatening anti-crop agents Note: EDEN has developed a list of useful definitions and acronyms specific to this course. Please be aware that “common definitions” do not exist for many agroterrorism and biosecurity management terms. However, while various agencies and disciplines may apply slightly different meanings to the same term, the broad concepts should be fairly similar.
Part 1 • Key Points about Terrorism against the U.S. • 5 categories of Weapons of Mass Destruction • Targeted Attacks against Agriculture
Question: How would you explain the broad concept of terrorism to someone unfamiliar with the term?
Definition: What is Terrorism? Terrorism can be defined as a malicious attempt to disrupt economic well-being, undermine peoples’ confidence, and/or destroy public health and safety by means of violence and/or threats to commit acts of violence. Sources: UKY; DHS
Points about terrorism against the U.S.: • Can be committed by an individual or group within or outside of the U.S. • Includes small scale and massive efforts • Spurred by religious, political, or ideological beliefs • Variety of weapons and/or agents may be used • Can be one event with immediate impact or planned/delivered over an extended period for a delayed, longer-term impact • Targets may include public events, buildings, infrastructure, agriculture, water supply, etc. Sources: Pate & Cameron; UKY; DHS
Question: Can you define the five categories of WMDs (weapons of mass destruction) used by terrorists? Hint: The acronym is C-BRNE
Definition: What are WMDs? Weapons of Mass Destruction (WMDs) are agents and devices used by terrorists with an intent to cause large scale destruction, and/or to inflict incapacitation, serious injury, and/or death to many people. The 5 WMD categories are known by the acronym C-BRNE: Chemical, Biological, Radiological, Nuclear, and Explosive

Question: How would you describe a specific form of terrorism against agriculture - - often referred to as agroterrorism or agri-terrorism?
Definition: What is Agroterrorism? • Agroterrorism (agri-terrorism) is a malicious attempt to disrupt or destroy the agricultural industry and/or food supply systems (i.e. processing, storage, and transportation).
Question: What categories of WMDs would most likely be used by an agroterrorist? Can you describe an agroterrorism scenario for each of these three types? Answer: Sources:
Possible Agroterrorism Scenarios • Chemical - use of a crop duster for aerial distribution of an irritating agent. • Biological – introduction of a pathogen to contaminate crops and disrupt U.S. economy • Explosive – destruction of a anhydrous plant with intent to propel chemical gases into the air Sources:
Question: Why might an agroterrorist “prefer” biological agents to other WMDs?
Cost-effective for agroterrorists to produce Can be easy to distribute Potential to turn into an epidemic Potential for high injury & mortality rates Potential to disrupt U.S. exports and effect economy Characteristics of Biological Agents Source: UKY;
Part 2 • What is Plant Biosecurity Management? • Pathogens attractive to terrorists • List of threatening anti-crop agents
For your information . . . This course specializes on plant biosecurity issues: preventing the introduction of biological agents (bacteria, viruses, fungi, and toxins) to U.S. food crops. It is important to note that the introduction of biological agents can be either intentional (a terrorist attempt) or unintentional (by human error). Therefore, when you teach this course to others, be sure to emphasize that plant biosecurity management is not only relevant to anti-terrorist activities, but that ongoing best management practices are also key to the every day protection of crops against unwanted pests, pathogens, and agents that are currently present or threaten plants in the U.S.
Question: How does agroterrorism relate to plant biosecurity management?
Definition: What is Plant Biosecurity Management? Plant Biosecurity Managementcan be defined as (a) preparing for, (b) responding to, and (c) recovering from a plant biosecurity problem, and (d) mitigating the risks of a plant biosecurity event. It includes a range of management activities performed by persons in the agricultural sector who are critically engaged in anti-terrorist activities to help assure the ongoing safety of the U.S. food supply.
Question: Why do agroterrorists seek certain pests or diseases to use as anti-crop agents?
Ease of production Ease of dissemination Low infective dose Short incubation period Difficult to diagnose in early stages High infectivity Short life cycle Stability in the environment Lack of availability of cost-effective treatments Absence of genetic resistance Terrorists look for these characteristics: Sources: Biological Warfare Against Crops, Simon Whitby, 2002
Question: Do you know of pathogens that meet at least some of those criteria, and therefore might be used in an agroterrorism attempt?
Plant pathogens that have potential as anti-crop agents in the U.S.: • Pyricularia oryzae (Rice Blast) • Puccinia graminis tritici (Stem Rust of Wheat) • Xanthomonas oryzae pv. Oryzicola (Sugarcane bacterial blight) • Phakopsora pacgyrhizi (Soybean Rust) • TBRV Virus (Tomato Black Ring) Phytophthora infestans(Late Blight of Potatoes) Sources: Whitby, 2002; UTK
Summary • Terrorism/agroterrorism can be committed by an individual or group within or outside of the U.S. • The 5 WMD categories are known by the acronym C-BRNE: Chemical, Biological, Radiological, Nuclear, and Explosive • Biological weapons include the use of bacteria, viruses, fungi, and toxins that are harmful to humans, plants and animals and/or deteriorate property. • Agroterrorism is a malicious attempt to disrupt or destroy the agricultural industry and/or food supply systems • Plant biosecurity management is relevant to the protection of crops against the intentional and unintentional introduction of unwanted pests, pathogens, and agents.
