Inclusion in other EU ranking systems	PHRR, BiOR2, FinnPRIO
Need of automatic approach	No
Description	This criterion considers factors that facilitate visual detection: • distinctiveness or specificity of symptoms α (the symptoms might look like those of other organisms or sources of damage such as mechanical damage or injury due to cold conditions), • ease of detection of the pest β according to the life stage that is likely to be present (some stages are more readily detected than others: adult insects e.g. may be easier to see than their eggs or viruses) and the location of the pest on/in the commodity (surface feeders may be more readily detected than internal feeders).
Scoring	Score = P(α, β) P(α, β) are likelihood factors for the pest passing inspection as explained below. α = 1 if symptoms are specific (α = 0 if not or if the symptoms do not develop on HC) β = 1 if visual detection of the pest is easy (β = 0 if not) If there is more than one host commodity, the highest P score is considered
	P	3	2	2	1
	α	0	1	0	1
	β	0	0	1	1
	If ‘No info’, apply the worst‐case scenario (Score = 3)
Data	List of host plants, host commodities, description of symptoms
Example	Xanthomonas citri could be present on citrus fruits with specific symptoms but is borne internally. P(1, 0) = 2
