Introduction Biosecurity is the strategies and efforts by society to protect people, animals, and the environment as a whole against any prevailing biological threats. The main objective of biosecurity is to protect human beings and animals against dangers associated with diseases and organisms within the environment. Biosecurity is successful if supported by an expert management system and other practical protocols that an institution may establish. The basic tools used in biosecurity are exclusion, elimination, and control of the diseases and organisms that pose threats to human health. Biosecurity is a management practice in defending human life against any possible biological threat. Biosecurity is a preventive measure that is designed to the risk of intentional removal of elements of valuable biological material. It involves a combination of practices and systems that are assembled in a very well-organized legitimate place which is considered to be the main source of the pathogens and other toxins. The term biosecurity is not like other kinds of security where we talk of guards, gates, and other machines that are used as security measures, biosecurity encompasses co-operations of scientists, efforts of technicians, those make policies, laws enforcers, and security engineers (Bacot, & Martin, 1998). A biological laboratory is where most biosecurity operations are carried out. Disease diagnosis, animal analysis, epidemiological studies, and pharmaceutical developments are carried out in biological laboratories. Materials that are used in biological laboratories are used for a justifiable purpose and it is here where large volumes of microorganisms are replicated. In the biological laboratory, cellular components are extracted for purposes of education, medical, and health purposes. Biosecurity programs are conducted in biological laboratories which have the following components:   * Personnel security   * Physical security   * Transport security   * Program management   * Information security   * Material and control security Terrorists used pathogens and other toxins in the past to threaten and cause disruption in society hence affecting both the political and economic position of these societies. International agreements have been established to eradicate the use of biological agents for malicious purposes by terrorists. Those who carry out such operations of threatening human life in society are considered to go against ethical values and do not respect the rights of people. Global treaties and other conventions have been put in place to curb the accessibility of unauthorized persons to biological agents and toxins that are present in the biological laboratories. To reduce the risk of bioterrorism, the harmonized international regime has been established to enhance biosecurity through the reinforcement of strands. The reinforcement of strands encompasses control of access to dangerous pathogens, transparency for sanctioned biodefense programs, the acts of terrorists to use science to challenge security among others (Appel, 2002). List of Agents Some agents are deemed responsible for biological insecurity in society. The US government has established that there are agents responsible for human infections and those which infect both humans and animals. There are
