EPPO Alert List
Purpose of the EPPO Alert List
The main purpose of the Alert List is to draw the attention of EPPO member countries to certain pests possibly presenting a risk to them and achieve early warning. It can also be used by EPPO to select candidates which may be submitted to a Pest Risk Analysis (PRA). Pests are marked with an asterisk* in the table below when a PRA is planned or under development within EPPO. The entry date corresponds to the date when the pest was added to the Alert List. Read a short introduction to the EPPO Alert List.

Previously listed pests
In order to keep the Alert List reasonably short, pests are included on the Alert List on a temporary basis. Pests may be submitted to a Pest Risk Analysis (PRA), and depending on the results of this PRA they may be transferred to the EPPO A1/A2 Lists of pests recommended for regulation as quarantine pests. For the other pests, after a certain period (usually 3 years), if the relevant EPPO Panels consider that sufficient alert has been given to the NPPOs, pests are removed from the Alert List.
At the request of both the EPPO Working Party on Phytosanitary Regulations and the Panel on Plant Quarantine Information, it was decided that the information on the organisms which were previously listed on the EPPO Alert List should remain available. The pests listed below have been removed from the EPPO Alert List or transferred to the EPPO A1 or A2 Lists. As a consequence, the EPPO Secretariat no longer updates their entries within the Alert List, but the information which was available at the time when they were deleted (i.e. mini datasheets with the reasons for deletion) can be retrieved from the EPPO Global Database in the section 'Documents'. For pests which were added to the EPPO A1 and A2 Lists, fuller datasheets are available or under preparation.
