Article 10.9.1.
For the purposes of the Aquatic Code, viral haemorrhagic septicaemia (VHS) means infection with VHS virus
(VHSV, synonym: Egtved virus) of the genus Novirhabdovirus of the family Rhabdoviridae.
Information on methods for diagnostic are provided in the Aquatic Manual.
Article 10.9.2.
Scope
The recommendations in this chapter apply to: rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutta),
grayling (Thymallus thymallus), white fish (Coregonus spp.), pike (Esox lucius), turbot (Scophthalmus maximus),
herring and sprat (Clupea spp.), Pacific salmon (Oncorhynchus spp.), Atlantic cod (Gadus morhua), Pacific cod
(G. macrocephalus), haddock (G. aeglefinus) and rockling (Onos mustelus). These recommendations also apply
to any other susceptible species referred to in the Aquatic Manual when traded internationally.
Article 10.9.3.
Importation or transit of aquatic animals and aquatic animal products for any purpose from a country,
zone or
compartment not declared free from viral haemorrhagic septicaemia
3. Preliminary control zone - VHS
Article 10.9.5
Viral haemorrhagic septicaemia free zone or free compartment
A zone or compartment within the territory of one or more countries not declared free from VHS may be declared free by the Competent Authority(ies)
of the country(ies) concerned if the zone or compartment meets the conditions referred to in points 1, 2 or 3 below.
If a zone or compartment extends over more than one country, it can only be declared an VHS free zone or compartment if all the Competent
Authorities confirm that the conditions have been met.
A zone or compartment where the species referred to in Article 10.9.2. are present but there has been no observed occurrence of the disease for at
least the past ten years despite conditions that are conducive to its clinical expression, as described in the corresponding chapter of the Aquatic
Manual, may be declared free from VHS when basic biosecurity conditions have been continuously met in the zone or compartment for at least
the past ten years.
OR
A zone or compartment where the last observed occurrence of the disease was within the past ten years or where the infection status prior to targeted
surveillance was unknown (e.g. because of the absence of conditions conducive to clinical expression as described in the corresponding chapter
of the Aquatic Manual) may be declared free from VHS when:
basic biosecurity conditions have been continuously met for at least the past two years; and
targeted surveillance, as described in Chapter 1.4. of the Aquatic Code, has been in place for at least the last two years without detection of
VHSV.
OR
A zone previously declared free from VHS but in which the disease is detected may be declared free
from VHS again when the following conditions have been met:
on detection of the disease, the affected area was declared an infected zone and a protection zone
was established; and
infected populations have been destroyed or removed from the infected zone by means that
minimise the risk of further spread of the disease, and the appropriate disinfection procedures (see
Aquatic Manual) have been completed; and
targeted surveillance, as described in Chapter 1.4. of the Aquatic Code, has been in place for at least
the last two years without detection of VHSV; and
previously existing basic biosecurity conditions have been reviewed and modified as necessary and
have continuously been in place for at least the past two years.

Article 1.4.1.
Introduction and objectives
1) Surveillance activities may be performed to achieve any of the following objectives:
a) demonstrating the absence of disease;
b) identifying events requiring notification as listed in Article 1.1.3. of the Aquatic Code;
c) determining the occurrence or distribution of endemic disease, including changes to their incidence or
prevalence (or its contributing factors), in order to:
i) provide information for domestic disease control programmes,
ii) provide relevant disease occurrence information to be used by trading partners for qualitative and quantitative risk
assessment.

GENERAL MANDATE OF THE OIE
General mandate of the OIE:
to improve animal health and welfare worldwide

Fallowing and
disinfection
Faroese production in tons of Atlantic salmon and rainbow trout
ISA
What will reduce the chance of
disease - The Faroe Island experience
Single year class. One generation in each fjord
All in – All out
Synchronized fallowing
Safe transportation of fish
No fish transportation between sites
Treatment of processing water and transport water
Safe handling of dead fish
Low fish density (65.000 fish in each 120 m pen)

How big zone do we need?
When is synchronized
fallowing possible?
Thank you!
