Preventative measures in case of Duck Viral Enteritis (MT)
• no free keeping on natural water during the 2 weeks before egg-laying
period
• infected natural water: no susceptible birds for 2 years except vaccinated
broiler ducks
• breeding and broiler flocks shall not be kept together
Official measures in case of Duck Viral Enteritis of the hatched birds
• birds showing clinical signs are killed
• birds not showing clinical signs
• immediate slaughter: heat treated meat products or vaccination (recovered flock)
• 30 days observation, no breeding, movement restriction until slaughter
• 28 days observation, hatching eggs are disinfected, separate hatching,
separate fattening
Official measures in case of suspected presence of Classical Swine Fever on a holding
• official supervision
• movement to and from the holding is prohibited or subject to authorization
• access ways to the holding and means of transport leaving it must be
disinfected
Specific Criteria of Contagious Bovine Pleuropneumonia (CBPP)
- no clinical or pathological evidence of CBPP (for the declaration of provisional freedom: at least for 3 years or 1 year if no vaccination)
- effective veterinary service
- effective meat inspection
- all evidence suggestive of CBPP is investigated by laboratory methods,
- diagnostic procedures capable of differentiating Mycoplasma infections
- effective reporting system
- effective system to prevent the introduction of infection
- if vaccination has been used, all vaccination against CBPP has ceased by the date of declaration of provisional freedom
Reaching free status in CBPP
- provisional freedom from disease
- 2 years
- freedom from the disease
- 2 years
- freedom from infection
Country free from CBPP infection without intermediate steps
• continuously free from CBPP from at least 10 years
• no vaccination for at least 10 years
• no clinical or pathological evidence for at least 10 years
• adequate disease surveillance and reporting system
• use of diagnostic procedures capable of differentiating Mycoplasma
infections
Re-establishing CBPP infection free status
• 2 years from the date of the last case
• demonstration that the outbreak did not represent endemic infection and that
the disease has been eradicated by the actions taken
Case of Bluetongue
- it presents clinical signs consistent with the presence of bluetongue
- it is an animal from which the bluetongue virus has been isolated and identified
- it is an animal which has tested positive to bluetongue serological tests or from which viral antigen or RNA specific to bluetongue has been identified
- it is a sentinel animal that has showed negative serological results in a previous test and has seroconverted from negative to positive for antibodies to at least one bluetongue serotype since that test
- a set of epidemiological data must indicate that the infection are the consequence of virus circulation and not the result of introduction of vaccination or seropositive animals
Suspected presence of Bluetongue
• place the holding under official surveillance
• compile an inventory of the animals and update when animals are born or
they die
• compile a list of places that could facilitate the survival or harbour the vector
or sites where its reproduction
• epidemiological investigation
• regular visits to the holdings with detailed clinical examinations or autopsy
if necessary
22
• no movement of animals in or out of the holding
• animals are confined when vectors are active
• treat animals, buildings and their surroundings with insecticides
• the carcasses of dead animals are destroyed, eliminated, incinerated or
buried
Officially confirmed presence of Bluetongue
- precede with slaughter if deemed necessary to present extension of the epidemic
- order the destruction, elimination, incineration or burial of the carcasses
- extend measures of official surveillance and movement restrictions to holding located within a radius of 20 km around the infected holdings
- implement vaccination programs if necessary
- epidemiological survey
- protection zone with a radius of 100 km
- surveillance zone with a radius of 50 km
Movement restrictions in case of American Foul Brood
- marking of bee colonies
- prohibition: antibiotic treatment and any intervention transmitting the disease
- laboratory examination from the colonies suspected of being diseased
Official measures is case of American Foul Brood
- killing of bee colonies
- killed bee colonies are burned and buried (+ products, comb, brood)
- burning and burial of all combustible material from the hive
- strict disinfection
- suspected of being contaminated: processing of products
Lifting restrictions in case of American Foul Brood
- no colonies and strict disinfection
- 60 day observation period (non-brooding period)
- strict disinfection
- if only suspected of being diseased and the laboratory ruled out: without disinfection
- if only colonies suspected of being contaminated: without disinfection after observation
Official measures in case of European Foul Brood
- obligatory treatment of all colonies in the protection zone
- checks every 2 weeks
- if denied: killing without state compensation
- weak bee colony: killing
- if + American foul brood: prohibition of treatment, killing the diseased colonies
- strict disinfection
- suspected of being contaminated: processing of products
Lifting restrictions in case of European Foul Brood
• no colonies and strict disinfection
• 15 days observation and strict disinfection
• if only colonies suspected of being diseased and the laboratory rules out: without disinfection
• if only colonies suspected of being contaminated: without disinfection after
observation
Movement restrictions in case of Acariosis
- marking of bee colonies
- prohibition: any intervention transmitting the disease
- laboratory examination from the colonies suspected of being diseased
Official measures in case of Acariosis
- obligatory treatment of all colonies in the protection zone
- if denied: killing without compensation
- honey and products: only after heat treatment
- disinfection (hive and equipment)
Lifting restrictions in case of Acariosis
• obligatory treatment + 1 year observation + checks
Low pathogenic avian influenza
an infection of poultry or other captive birds caused by avian influenza virus subtypes H5 or H7 that do not come within the definition of HPAI
Highly pathogenic avian influenza
an infection of poultry or other captive birds caused by
o avian influenza viruses of the subtype H5 or H7 with genome sequences coding for multiple basic amino acids at the cleavage site of hemagglutinin molecule, indicating that the hemagglutinin molecule can be cleaved by a host ubiquitous protease or
‘o avian influenza viruses with a intravenous pathogenicity index in 6 week old chickens greater than 1.2
Measures to be applied on holding where outbreaks of Avian Influenza outbreaks are suspected
• count or estimate number of birds and mammals
• list of birds and mammals that are sick, dead or likely to be infected on the holding and updated to reflect births and deaths
• keep birds inside and limit their contact with wild birds
• no movement of poultry in or out of the holding
• no carcasses, meat or any material likely to transmit avian influenza may
leave the holding without authorization
• no eggs may leave the holding
• control movement of people, mammals, vehicles and equipment to and from the holding
• disinfection at entrances and exits of buildings housing poultry
• stamping out may be applied
• temporary control zones may be established
Definition of a long journey
a journey that exceeds 8 hours starting from when the first animal of the consignment is moved
Protection of animals during transport
the regulation shall not apply to transport which does not take place in connection with an economic activity or directly to or from veterinary clinics
Transport documentation
- their origin and their ownership
- their place of departure
- the date and time of departure
- their intended place of destination
- the expected duration of the intended journey
