Biosecurity, as originally conceptualized, is a set of preventive measures designed to reduce the risk of transmission of infectious diseases in crops and livestock, quarantined pests, invasive alien species, and living modified organisms. The emerging nature of biosecurity threats means that small scale risks blow up rapidly, thus an effective policy becomes a challenge for there are limitations on time and resources available for analysing threats and estimating the likelihood of their occurrence.
Biosecurity has multiple meanings and is defined differently according to various disciplines. The term was first used by the agricultural and environmental communities. Starting from the late 1990s in response to the threat of biological terrorism, biosecurity encompasses the prevention of the intentional removal (theft) of biological materials from research laboratories. These preventive measures are a combination of systems and practices put into its place at bioscience laboratories to prevent the use of dangerous pathogens and toxins for malicious use, as well as by customs agents and agricultural and natural resource managers to prevent the spread of these biological agents.
Advances in technology have meant that many civilian research projects in medicine have the potential to be used in military applications (dual-use research) and biosecurity protocols are used to prevent dangerous biological materials from falling into the hands of malevolent parties. The National Academy of Sciences define biosecurity as "security against the inadvertent, inappropriate, or intentional malicious or malevolent use of potentially dangerous biological agents or biotechnology, including the development, production, stockpiling, or use of biological weapons as well as outbreaks of newly emergent and epidemic disease". Biosecurity requires the cooperation of scientists, technicians, policy makers, security engineers, and law enforcement officials.
Controversial experiments in synthetic biology, including the synthesis of poliovirus from its genetic sequence, and the modification of H5N1 for airborne transmission in mammals, led to calls for tighter controls on the materials and information used to perform similar feats. Ideas include better enforcement by national governments and private entities concerning shipments and downloads of such materials, and registration or background check requirements for anyone handling such materials.
Initially, health security or biosecurity issues have not been considered as an international security issue especially in the traditional view of international relations. However, some changes in trend have contributed to inclusion of biosecurity (health security) in discussions of security.
As time progressed, there was a movement towards securitization. Non-traditional security issues such as climate change, organized crime, terrorism, and landmines came to be included in the definition of international security. There was a general realization that the actors in the international system not only involved nation-states but also included international organizations, institutions, and individuals, which ensured the security of various actors within each nation became an important agenda. Biosecurity is one of the issues to be securitized under this trend. On January 10, 2000, the UN Security Council convened to discuss HIV/AIDS as a security issue in Africa and designated it a threat in the following month. The UNDP Millennium Development Goals also recognize health issues as international security issue. Several instances of epidemics that followed such as SARS increased awareness of health security (biosecurity). Recently several factors have rendered biosecurity issues more severe. There is a continuing advancement of biotechnology which increases the possibility for malevolent use, evolution of infectious diseases, and globalizing force which is making the world more interdependent and more susceptible to spread of epidemics.
Some uncertainties about the policy implementation for biosecurity remain for future. In order to carefully plan out preventive policies, policy makers need to be able to somewhat predict the probability and assess the risks; however, as the uncertain nature of the biosecurity issue goes it is largely difficult to predict and also involves a complex process as it requires a multidisciplinary approach. The policy choices they make to address an immediate threat could pose another threat in the future, facing an unintended trade-off. Policy makers are also constantly looking for a more effective way to coordinate international actors- governmental organizations and NGOs- and actors from different nations so that they could tackle the problem of resource overlap.
Components of a laboratory biosecurity program include:
Animal biosecurity is the product of all actions undertaken by an entity to prevent introduction of disease agents into a specific area. Animal biosecurity differs from biosecurity which are measures taken to reduce the risk of infectious agent theft and dispersal by means of bioterrorism. Animal biosecurity is a comprehensive approach, encompassing different means of prevention and containment. A critical element in animal biosecurity, biocontainment, is the control of disease agents already present in a particular area, and works to prevent novel transmissions. Animal biosecurity may protect organisms from infectious agents or noninfectious agents such as toxins or pollutants, and can be executed in areas as large as a nation or as small as a local farm.
Animal biosecurity takes into account the epidemiological triad for disease occurrence: the individual host, the disease, and the environment in contributing to disease susceptibility. It aims to improve nonspecific immunity of the host to resist the introduction of an agent, or limit the risk that an agent will be sustained in an environment at adequate levels. Biocontainment, an element of animal biosecurity, works to improve specific immunity towards already present pathogens.
Biosecurity means the prevention of the illicit use of pathogenic bioorganisms by laboratory staff or others. It also means the protection of laboratory staff from being infected by pathogenic bioorganisms.
Medical countermeasures (MCMs) are products such as biologics and pharmaceutical drugs that can protect from or treat the effects of a chemical, biological, radiological, or nuclear (CBRN) attack. MCMs can also be used for prevention and diagnosis of symptoms associated with CBRN attacks or threats.
The FDA runs a program called the "FDA Medical Countermeasures Initiative" (MCMi). It helps support "partner"[a] agencies and organizations prepare for public health emergencies that could require MCMs.
The federal government provides funding for MCM-related programs. In June 2016, a Senate Appropriations subcommittee approved a bill that would continue funding four specific medical countermeasure programs:
The destruction of the World Trade Center in Manhattan on September 11, 2001 by terrorists and a subsequent wave of anthrax attacks on U.S. media and government outlets (both real and hoax) led to increased attention on the risk of bioterrorism attacks in the United States. This resulted in proposals for serious structural reforms, national or regional border controls, and a single co-ordinated system of biohazard response.
One of the major challenges of biosecurity is that harmful technology has become more available and accessible. Biomedical advances and the globalization of scientific and technical expertise have made it possible to greatly improve public health. However, there is also the risk that these advances can make it easier for terrorists to produce biological weapons.
The proliferation of high biosafety level laboratories around the world has resulted in concern about the availability of targets for those that might be interested in stealing dangerous pathogens. Emerging and re-emerging disease is also a biosecurity concern. The growth in containment laboratories is often in response to emerging diseases, and many new containment labs' main focus is to find ways to control these diseases. By strengthening national disease surveillance, prevention, control and response systems, the labs have improved international public health.
Research into biosecurity and biosafety conducted by the United Nations University Institute for the Advanced Study of Sustainability (UNU-IAS) 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".
In the October 2011 Bio-Response Report Card, the WMD Center stated that the major challenges to biosecurity are:
Communication between the citizen and law enforcement officials is important. Indicators of agro-terrorism at a food processing plant may include persons taking notes or photos of a business, theft of employee uniforms, employees changing working hours, or persons attempting to gain information about security measures and personnel. Unusual activity is best handled if reported to law enforcement personnel promptly.
Communication between policymakers and life sciences scientists is also important.
The MENA region, with its socio-political unrest, diverse cultures and societies, and recent biological weapons programs, faces particular challenges.

The advance of the life sciences and biotechnology has the potential to bring great benefits to humankind through responding to societal challenges. However, it is also possible that such advances could be exploited for hostile purposes, something evidenced in a small number of incidents of bioterrorism, particularly by the series of large-scale offensive biological warfare programs carried out by major states in the last century. Dealing with this challenge, which has been labelled the "dual-use dilemma," requires a number of different activities. However, one way of ensuring that the life sciences continue to generate significant benefits and do not become subject to misuse for hostile purposes is a process of engagement between scientists and the security community, and the development of strong ethical and normative frameworks to complement legal and regulatory measures that are developed by states.
