If the epizootic investigation reveals that the disease could have been introduced from an approved zone or from another approved farm, or could have been transferred to another approved farm as a result of the movement of fish, eggs or gametes, vehicles or persons, or in any other way, those zones or farms shall be considered suspect and the appropriate measures shall apply.
Če epizootiološka preiskava pokaže, da se je bolezen morda prenesla iz odobrene cone ali iz druge odobrene gojilnice, ali da se je morda prenesla na drugo odobreno gojilnico kot posledica gibanja rib, jajčec ali gamet, vozil ali ljudi, oziroma na kakršen koli drug način, je te cone ali gojilnice treba obravnavati, kot sumljiva, ter izvesti ustrezne ukrepe.
