A summary of this process is given here, followed by a description of the qualitative methodology used in this risk analysis. Likelihood of The likelihood of entry describes the likelihood that a quarantine pest will enter Australia as a result of trade in a given longan, be distributed in a viable state in the PRA area and subsequently be transferred to a host. It is based on pathway scenarios depicting necessary steps in the sourcing of the longan for export, its processing, transport and storage, its use in Australia and the generation and disposal of waste. In particular, the ability of the pest to survive is considered for each of these various stages. The likelihood of entry estimates for the quarantine pests for a longan are based on the use of the existing commercial production, packaging and shipping practices of the exporting Vietnam. Details of the existing commercial production practices for the longan are set out in Chapter 3. These practices are taken into consideration by the department when estimating the likelihood of entry. For the purpose of considering the likelihood of entry, the department divides this step into two components: Likelihood of importation—the likelihood that a pest will arrive in Australia when a given longan is imported. Likelihood of distribution— the likelihood that the pest will be distributed, as a result of the processing, sale or disposal of the longan, in the PRA area and subsequently transfer to a susceptible part of a host. Factors to be considered in the likelihood of importation may include: distribution and incidence of the pest in the source area occurrence of the pest in a life-stage that would be associated with the longan mode of trade (for example, bulk, packed) volume and frequency of movement of the longan along each pathway seasonal timing of imports pest management, cultural and commercial procedures applied at the place of origin of transport and conditions of storage compared with the duration of the lifecycle of the pest vulnerability of the life-stages of the pest during transport or storage incidence of the pest likely to be associated with a consignment commercial procedures (for example, refrigeration) applied to consignments during transport and storage in the Vietnam of origin, and during transport to Australia. Factors to be considered in the likelihood of distribution may include: commercial procedures (for example, refrigeration) applied to consignments during distribution in Australia dispersal mechanisms of the pest, including vectors, to allow movement from the pathway to a host
