An Overview of Food Safety and Agrosecurity

Agricultural Disaster Preparedness and Recovery December 04, 2013 Print Friendly and PDF
Food security used to describe the stability and supply of sufficient food for a given population. Today the term also refers to food safety and food biosecurity. Agricultural operations, processing plants and retail operations serve in the national food defense system.

 

Agroterrorism in the U.S.: An Overview

Since the attacks of 9/11, vulnerabilities of the nation's infrastructure have been analyzed and discussed. The United States has identified protection of national systems and infrastructure, such as transportation, communication, water supply, and agriculture networks, as priorities to defend against terrorism.

Terrorism is the unlawful use of force, violence, or implied harm against persons and property to intimidate or coerce a government, the civilian population, or any element of it, to further political, religious, or ideological aims. Agroterrorism is the deliberate introduction of detrimental agents, biological and otherwise, into agricultural and food processing systems with the intent of causing actual or perceived harm. The broad areas of agriculture that could provide targets in an agroterrorism event are farm animals and livestock, plant crops and food processing, and distribution and retailing systems.

Bioterrorism is closely related to agroterrorism. Bioterrorism is defined as the use of biological agents in a deliberate, harmful attack or terrorism using the weapons of biological warfare such as anthrax, smallpox, or other pathogens. Bioterrorism attacks can be directed not only at agricultural targets but also at the general public and key domestic infrastructure systems and personnel. In this discussion, biological agents are considered the most probable weapon to be used to launch an agroterrorism event.

Consequences of a U.S. Agroterrorism Event

Agriculture and the food industry are important to the U.S. economy. The U.S. Department of Agriculture's Agricultural Research Service (USDA-ARS) estimates one person in eight works in some part of the agriculture/food sector. Cattle and dairy farmers alone earn about $50 billion a year in meat and milk sales. Domestically, about 10% of the U.S. Gross Domestic Product (GDP) is related to agriculture and food production. Even without agroterrorism, livestock disease costs the U.S. economy about $17.5 billion and crop diseases account for about $30 billion. These are the baseline losses to which the financial impact of an actual agroterrorism event would be added.

In the event of an agroterrorism event occurring in the U.S., the potential for disrupting our export market would be immense. International trade is crucial because it provides a market for a major part of our crop production and a growing share of meat output. Overall, 8% of the U.S. GDP is due to international trade. For comparison, about 30% of U.S. farm cash receipts are generated by exports. Proportionately, U.S. agriculture industries rely on export markets more heavily than other sectors of U.S. industry. An agroterrorism event that instigated fear or uncertainty in our international customers could be financially devastating to U.S. agricultural interests.

Vulnerability of the U.S. Agriculture System

Various factors led to the heightened state of vulnerability of the U.S. to an agroterrorism event. As previously discussed, agriculture, food processing, and food retailing contribute significantly to the U.S. economy. As urban growth has occurred, agricultural operations, including farms, packinghouses, and processing plants have become larger, more centralized, and more intensive. It is this type of industrial concentration that perhaps increases the vulnerability of the U.S. agriculture system; as almost all agricultural sectors consolidate, their overall size generally increases. Thus, the impact of a targeted agroterrorism event affecting just one entity could still have a serious adverse impact. For example, foot-and-mouth disease (FMD) confined to a very small geographically distinct herd is a vastly different situation than FMD occurring through intentional spread of the disease in a large cattle operation. Although large operations typically have greater economies of scale, they also lead to these types of vulnerabilities.

There are other reasons to be aware of the need for better security in agricultural operations. It is difficult and expensive to secure large areas of farmland with fences, gates, and monitoring devices, yet it is incumbent upon producers to provide security in these areas. Although packinghouses and processing plants are more easily controlled from a physical perimeter standpoint, more personnel are then needed to be screened and trained in specifics of plant security. More and more, security auditors focus on specific areas in which clients can improve procedures and practices. Defense against terrorism must become ingrained in the normal operations of all agricultural operations before the U.S. can expect an improvement in the current state of readiness against an attack.

The Bioterrorism Act of 2002

The events of 9/11 reinforced the need to enhance the security of the U.S. One broad area of vulnerability is agriculture and specifically food production. The term food security, which traditionally meant the stability and supply of sufficient food for a given population, suddenly took on a different meaning. On June 12, 2002, the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (the Act) was signed into law by the U.S. Congress. The Food and Drug Administration (FDA) is responsible for developing and implementing regulations on the following major provisions of the Act: Registration of Food Facilities, Prior Notice of Imported Food, Establishment and Maintenance of Records, and Administrative Detention. The definition of food used in these regulations includes food and beverages for human and animal consumption, including dietary supplements, infant formula, and food additives. It does not, however, cover food products such as meat and poultry, which are regulated by the USDA-Food Safety and Inspection Service (FSIS). The Act was designed to improve the ability of the U.S. to prevent, prepare for, and respond to bioterrorism and other public health emergencies.

Prevention, Detection, and Mitigation

Ideally, terrorism aimed at the food supply would be 100% preventable. In the aftermath of 9/11, many resources were shifted from food safety to food biosecurity, with the intent to try to install sufficient deterrents that would lead to an improved condition of readiness within agriculture and food sectors. State and federal agencies, along with trade organizations and third-party auditors, developed better and more thorough auditing tools and checklists that focused on security aspects for processing plants, their products, and their personnel.

However, experience with naturally occurring outbreaks of foodborne disease has demonstrated that no existing preventive system is 100% effective. To some degree, improved speed of detection of a bioterrorism event can help minimize impact of a particular event. After 9/11, agencies increased their inspection and analytical capabilities in response to increased needs to respond quickly to a bioterrorism threat. The anthrax incidents that occurred after 9/11, although not specifically agroterrorism, highlighted to authorities the need for a networked system of laboratories with pathogen- and toxin-detection capabilities.

Mitigation is one means of dealing with an actual or threatened agroterrorism event. The FDA, through the Bioterrorism Act of 2002, requires all food plants to register with the agency. They also require prior notice for imported food shipments as well as better record-keeping on the part of food processors and handlers. Should prevention fail, public safety will have to rely on mitigation and containment strategies. One of the reasons the FDA is requesting this information is to enhance traceability of food products and the efficacy of product recalls. Recalls involve removing products from the commerce stream after they have left the distributor. Products may be in transit, at the retail level, or even in consumers' homes. Retrieving potentially contaminated products before they can be consumed is an effective way to limit the public health impact of contaminated food. Most biosecurity audits within food processing, handling, and retailing facilities now identify product recalls, and the ability to quickly and effectively execute them, as an important approach to their overall anti-terrorism strategy.

Summary

The U.S. has not been the victim of a large-scale, successful agroterrorism attack. However, there are serious vulnerabilities within our agricultural and food processing systems that must be addressed. Through an iterative process of risk assessment, risk control, and verification of implemented deterrents, all pertinent agricultural interests, regulators, scientists, and public health officials can improve the defensive position of this key industry and strive to reduce the threat of agroterrorism as much as possible.
