Part 2 - Pest Risk Assessment - Categorisation (20 minutes)<br />
At the outset, it may not be clear which pest(s) identified in Stage 1 qualify as<br />
potential quarantine pests. The categorisation process examines whether the criteria<br />
in the definition for a quarantine pest are satisfied for each pest originally identified<br />
before the <strong>PRA</strong> continues.<br />
1. Identity of the pest<br />
• What is the organism?<br />
• Is it clearly a single taxonomic entity and can it be adequately distinguished<br />
from other entities of the same rank?<br />
• If the causal agent of particular symptoms has not yet been fully identified,<br />
has it been shown to produce consistent symptoms and to be transmissible?<br />
Pest identity<br />
Pest type<br />
If the answer is no, the <strong>PRA</strong> process may stop. Further research may be necessary<br />
to go on with the <strong>PRA</strong>. If the <strong>PRA</strong> continues, information pertaining to other similar<br />
pests may be required and assumptions or areas of uncertainty clearly stated.<br />
2. Presence or absence in the <strong>PRA</strong> area<br />
• Does the pest occur in the <strong>PRA</strong> area?<br />
• If so, is the pest widely distributed in the <strong>PRA</strong> area?<br />
Present in <strong>PRA</strong><br />
area?<br />
Widely<br />
distributed in<br />
<strong>PRA</strong> area?<br />
Important<br />
assumptions<br />

If the pest is present and widely distributed in the <strong>PRA</strong> area, the <strong>PRA</strong> may stop<br />
(remember the definition of a quarantine pest). If the pest is present in the <strong>PRA</strong><br />
area, but not widely distributed there, it should be under official control or expected<br />
to be under official control in the near future (see Question 3). If the pest is absent<br />
from the <strong>PRA</strong> area, continue with Question 4.<br />
