ANNEX A U.K. DEFINITIONS OF ‘AVIAN INFLUENZA’ AND ‘NEWCASTLE DISEASE’

CHAPTER I U.K. Avian influenza

‘Avian influenza’ means an infection of poultry caused by any influenza A virus which has an intravenous pathogenicity index (IVPI) in six-week-old chickens greater than 1,2 or any infection with influenza A virus of H5 or H7 sub-type for which nucleotide sequencing has demonstrated the presence of multiple basic amino acids at the cleavage site of the haemagglutinin.

The IVPI has to be determined according to the following method:

Intravenous pathogenicity index (IVPI) U.K.

1. Infective allantoic fluid from the lowest passage level available, preferably from the initial isolation without any selection, is diluted 10¹ in sterile isotonic saline. U.K.

2. 0,1 ml diluted virus is injected intravenously into each of 10 six-week-old chickens (specific pathogen free birds should be used). U.K.

3. Birds are examined at 24 hour intervals for 10 days. U.K.

4. At each observation each bird is recorded normal (O), sick (1), severely sick (2) or dead (3). U.K.

5. Record results and calculate index as shown in this example: U.K.

a This has to be a subjective clinical judgement but normally this would involve birds showing more than one of the following signs: respiratory involvement, depression, diarrhoea, cyanosis of exposed skin or wattles, oedema of face and/or head, nervous signs.
Index = mean score per bird per observation =
Clinical Signs	Days after inoculation (number of birds)										Total	Score
	1	2	3	4	5	6	7	8	9	10
Normal	10	2	0	0	0	0	0	0	0	0	12 × 0	= 0
Sick	0	4	2	0	0	0	0	0	0	0	6 × 1	= 6
Severely sicka	0	2	2	2	0	0	0	0	0	0	6 × 2	= 12
Dead	0	2	6	8	10	10	10	10	10	10	76 × 3	= 228
Total = 246

CHAPTER II U.K. Newcastle disease

‘Newcastle disease’ means an infection of poultry caused by any avian strain of the paramyxovirus 1 with an intracerebral pathogenicity index (ICPI) in one-day-old chicks greater than 0,7.

The ICPI has to be determined according to the following method:

Intracerebral pathogenicity index text (ICPI) U.K.

1. Infective freshly harvested allantoic fluid (HA titre must be greater than 2⁴) is diluted 1:10 in sterile isotonic saline (antibiotics must not be used). U.K.

2. 0,05 ml of the diluted virus is injected intracerebrally into each 10 one-day-old chicks (i.e. 24 - 40 hours after hatching). The chicks should be hatched from eggs obtained from a specific pathogen-free flock. U.K.

3. The birds are examined at intervals of 24 hours for eight days. U.K.

4. At each observation each bird is scored: 0 = normal; 1 = sick; 2 = dead. U.K.

5. The index is calculated as shown in the following example: U.K.

Index = is a mean score per bird of observation =
Clinical signs	Days after inoculation (number of birds)								Total	Score
	1	2	3	4	5	6	7	8
Normal	10	4	0	0	0	0	0	0	14 × 0	= 0
Sick	0	6	10	4	0	0	0	0	20 × 1	= 20
Dead	0	0	0	6	10	10	10	10	46 × 2	= 92
Total = 112

ANNEX B U.K. CRITERIA FOR RECOGNISED VACCINES

1. General criteria U.K.

A.

Vaccines have to be registered by the competent authorities of the third country concerned before being allowed to be distributed and used. For this registration the competent authorities have to rely on a complete file containing data about efficacy and innocuity; for imported vaccines the competent authorities can rely on data checked by the competent authorities of the country where the vaccine is produced, as far as these checks have been carried out in conformity with internationally accepted standards.

B.

Furthermore importation or production and distribution of the vaccines have to be controlled by the competent authorities of the third country concerned.

C.

Before distribution is allowed, each batch of vaccines has to be tested on innocuity, in particular regarding attenuation or inactivation and absence of undesired contaminating agents, and on efficacy on behalf of the competent authorities.

2. Specific criteria U.K.

A.

Live attenuated Newcastle disease vaccines shall be prepared from a Newcastle disease virus strain for which the master seed has been tested and shown to have an intracerebral pathogenicity index (ICPI) of:

either

(i)

less than 0,4 if not less than 10⁷ EID₅₀ are administered to each bird in the ICPI test;

or

(ii)

less than 0,5 if not less than 10⁸ EID₅₀ are administered to each bird in the ICPI test.

B.

Inactivated Newcastle disease vaccines shall be prepared form a Newcastle disease virus strain with an intracerebral pathogenicity index (ICPI) in one-day-old chicks of less than 0,7 if not less than 10⁸ EID₅₀ are administered to each bird in the ICPI test.

ANNEX C U.K. MINIMAL MEASURES TO BE TAKEN WHEN SANITARY SLAUGHTER IS PRACTISED TO ELIMINATE OUTBREAKS OF AVIAN INFLUENZA OR NEWCASTLE DISEASE

1. In case of suspicion the holding concerned shall be placed under official supervision. This shall in particular mean that: U.K.

(a)

all necessary samples shall be taken without delay and sent to a laboratory approved by the competent authorities for diagnosis;

(b)

a record shall be made of all categories of poultry kept on the holding showing number of dead and diseased animals; this record shall be kept up-to-date and should be checked at each official visit;

(c)

all poultry shall be kept isolated and, whenever possible, in their living quarters;

(d)

no poultry is allowed to enter or to leave the holding;

(e)

all movements of persons, vehicles, materials etc. onto and from the holding shall be subject to official authorization;

(f)

table eggs can leave the holding after adequate disinfection or can be sent directly to an installation where they receive an adequate heat treatment;

(g)

appropriate means of disinfection have to be used at the entrances of buildings housing poultry and of the holding itself;

(h)

an epizootiological inquiry has to be carried out to discover the source of infection and its possible spread;

(i)

possibly infected contact premises, i. e. these known from the inquiry meant in point (g) have to be put also under official surveillance.

2. As soon as the presence of the disease is officially confirmed on a holding, the following measures shall be taken in addition of those mentioned under point 1: U.K.

(a)

all poultry on the holding shall be killed on the spot without any delay; their carcasses and eggs shall be destroyed; these operations have to be carried out in a way which minimizes the risk of spreading disease;

(b)

any substance or waste liable to be contaminated shall be destroyed or treated in a way to ensure destruction of any virus present;

(c)

the meat of poultry slaughtered during the presumed incubation period should be traced and destroyed;

(d)

hatching eggs laid during the presumed incubation period should be traced and destroyed; poultry which hatched from such eggs shall be placed under official surveillance;

(e)

after carrying out killing and destruction operations the premises shall be thoroughly cleansed and desinfected;

(f)

no poultry shall be reintroduced onto the holding until at least 21 days after the end of the disinfection operations.

3. The operations mentioned in point 2 may be restricted to parts of holdings which form an epizootiological unit as far as the necessary guarantees exist to avoid spread of the disease to the non-infected units of the holding. U.K.

4. Around confirmed outbreaks of disease a protection zone with a minimum radius of 3 km and a surveillance zone with a minimum radius of 10 km shall be implemented. In these zones stand-still measures and controlled movements of poultry shall be in force until at least 21 days after the end of the disinfection operations on the infected holding. Before lifting the measures in these zones the authorities shall carry out the necessary inquiries and sampling of the poultry holdings to confirm that disease is no longer present in the region concerned. U.K.

5. The operations mentioned in this Annex have to be carried out by or under the supervision of the official veterinary authorities. U.K.
