For each suspected occurrence for which a positive result in the screening test(s) has been identified according to, for the listed plant material and for all other cases, the relevant methods set out in Annex II, and confirmation or refutation by completion of the said methods is awaited, there should be retention and appropriate conservation of:

• all tubers sampled and, wherever possible, all plants sampled,

• any remaining extract and additional prepared material for the screening test(s) e.g. immunofluorescence slides,

  and

• all relevant documentation,

until the completion of the said methods.

Retention of the tubers will enable variety testing to be undertaken where appropriate.

In the case of positive confirmation of the organism, there should be retention and appropriate conservation of:

• the material specified in paragraph 1,

• a sample of the infected tomato or eggplant material inoculated with the tuber or plant extract, where appropriate,

  and

• the isolated culture of the organism,

until at least one month after the notification procedure under Article 5(2).
