The EFSA Panel on Plant Health performed a pest categorisation of Cadang-Cadang viroid for the
European Union (EU) territory. Coconut cadang-cadang viroid (CCCVd) is a well-known viroid for which
efficient molecular detection assays are available. It is transmitted by vegetative multiplication of infected
hosts, by seed and pollen and, possibly, by the action of unknown vector(s). CCCVd is reported from a few
countries in Asia and is not known to occur in the EU. It therefore does not meet one of the criteria for
being a Union regulated non-quarantine pest. The host range of CCCVd is restricted to Arecaceae species
(palms), in particular coconut and it is listed on all known hosts in Annex IIAI of Directive 2000/29/EC.
CCCVd is expected to be able to enter in the EU and to be able to establish in the open in the
southernmost regions of the EU and elsewhere under protected cultivation. It has the potential to
subsequently spread via plants for planting and possibly other mechanisms. CCCVd is able to cause
severe symptoms in some Arecaceae species while others seem less affected. The potential impact of
CCCVd if introduced in the EU is very difficult to assess. Given that the spread potential is, as for
other viroids, likely to be limited, the potential impact is estimated to be limited in extent but this
judgement is affected by large uncertainties. Overall, CCCVd meets all the criteria evaluated by EFSA
to qualify as Union quarantine pest. The main knowledge gaps concern (1) the relationships between
CCCVd-related RNAs and CCCVd, (2) the origin and volume of the trade in palm seeds and plants for
planting imported in the EU (3) the efficiency of natural spread under EU conditions and (4) host
status and susceptibility of many palm species grown in the EU. [-]
