biology of the specific pests under consideration. In addition, the operating procedures must prevent the introduction of organisms into the facility that could contaminate, kill or transmit contained pests. Effective containment involves the use of trained personnel, appropriate and documented operational procedures, effective use of primary containment devices and facilities designed to limit access to authorized personnel. Risk Assessment and Containment Levels Facilities that handle plant pests should be constructed and operated to achieve the containment levels required for the pests concerned. The level required depends on the risk of the plant pest escaping and becoming established in the environment and on the environmental, economic, agricultural, forestry and trade consequences of such an introduction. Facilities that handle plant pests should be constructed and operated to achieve the containment levels required for the pests concerned. The level required depends on the risk of the plant pest escaping and becoming established in the environment and on the environmental, economic, agricultural, forestry and trade consequences of such an introduction. The containment requirements for a particular organism are frequently project-specific, and are determined after assessing pest risk factors such as: The known presence or absence of the organism in Canada; Its host and the local presence of potential hosts; The existence of, or the potential for, significant organism biotypes or strains that are exotic to an area; The history of the organism in new environments; The virulence or aggressiveness of the organism; The availability of pest risk information; The nature of the proposed work (in vitro, in vivo or large-scale in vivo); The location, proximity of suitable hosts and time of year of the proposed work; The mode of transmission or spread (e.g., Active flight, passive airborne, contact, soil-borne, water-borne); Its potential rate of and long-distance spread; The presence of vectors in Canada (e.g., Arthropods, fungi, nematodes); The presence of vectors in or near the containment facility; The persistence of the organism in the environment and its potential for overwintering; Environmental requirements for establishment and spread; The potential capacity to control or eradicate the organism if it escapes; The potential for economic or environmental loss from the organism; The economic and environmental significance of potential pest organisms and their host plants; and Biosecurity-related risks (e.g., the potential for theft and misuse).
