Past 2 Flashcards
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)
