Bovine tuberculosis of farmed cervidae
General provisions
The recommendations in this chapter are intended
to manage the human and animal health risks associated with Mycobacterium bovis (M. bovis)infection
in domestic (permanently captive and owned free-range) farmed cervidae
(red deer, wapiti, sika, samba, rusa, fallow deer, white-tailed,
black-tailed and mule deer [Cervus elephus, C. canadensis, C. nippon, C. unicolor unicolor, C. timorensis, Dama
dama dama, Odocoileus virginianus
borealis, Odocoileus hemionus columbianus and Odocoileus hemionus hemionus]). The
chapter does not address the management of tuberculosis in wild cervid
populations.
Standards for diagnostic tests are described in the Terrestrial Manual.
Country or zone free from bovine tuberculosis
of farmed cervidae
To qualify as free from bovine tuberculosis of
farmed cervidae, a country or zone should
satisfy the following requirements:
M. bovisinfection in
domestic bovines and in farmed cervidae as specified in Article 11.6.1. is a notifiable disease in
the country;
an ongoing awareness programme should be
in place to encourage reporting of all cases suggestive of tuberculosis;
regular and periodic testing of all herds of
farmed cervidae has demonstrated that M.
bovisinfection was
not present in at least 99.8% of the herds and 99.9%
of the farmed cervidae in the country or zone for
three consecutive years;
a surveillance programme
should be in place to detect bovine tuberculosis in the country
or zone through
ante- and post-mortem inspections as described in Chapter 6.2.;
if the surveillance programme
described in points 3 and 4 above demonstrated that M. bovisinfection was
not present in at least 99.8% of the herds and 99.9%
of the farmed cervidae in the country or zone for
five consecutive years, surveillance may
be maintained through ante- and post-mortem inspections as described
in Chapter 6.2.;
farmed cervidae introduced into a country or zone free from bovine tuberculosis should be accompanied by a certificate from an official veterinarian attesting that they come from a country, zone, compartment or herd free from bovine tuberculosis or comply with the relevant provisions in Article 11.6.5. or in Article 11.6.6.
Compartment free from bovine tuberculosis of farmed cervidae
To qualify as a compartment free from bovine tuberculosis of farmed cervidae, the Veterinary Authority should be able to certify that the following requirements are satisfied:
all farmed cervidae:
showed no sign of bovine tuberculosis or lesions at ante- or post-mortem inspection for at least three consecutive years;
were over six weeks of age at the time of the first test and have shown a negative result to at least two tuberculin tests carried out at an interval of a minimum of six months, the first test being performed at least six months following the slaughter of the last affected animal;
met one of the following conditions:
showed a negative result to a twice yearly tuberculin test to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is more than 1% of all herds in the country or zone during the last two years; or
showed a negative result to an annual tuberculin test to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is more than 0.2% but not more than 1% of all herds in the country or zone during the last two years; or
showed a negative result to a tuberculin test every three years to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is not more than 0.2% of all herds in the country or zone during the last four years; or
showed a negative result to a tuberculin test every four years to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is not more than 0.1% of all herds in the country or zone during the last six years;
farmed cervidae introduced into the compartment come from a herd free from bovine tuberculosis. This condition may be waived for animals which have been isolated for at least 90 days and which, prior to entry into the compartment, were subjected to at least two tuberculin tests carried out at a six-month interval with negative results with the second tuberculin test performed during the 30 days prior to entry into the compartment;
farmed cervidae in a compartment free from bovine tuberculosis are protected from contact with wildlife reservoirs of bovine tuberculosis and are managed under a common biosecurity plan protecting them from contamination with M. bovis, and the compartment has been approved by the Veterinary Authority in accordance with Chapters 4.3. and 4.4.
Herd free from bovine tuberculosis of farmed cervidae
To qualify as free from bovine tuberculosis, a herd of farmed cervidae should satisfy the following requirements:
the herd is in a country, a zone or a compartment free from bovine tuberculosis and is certified free by the Veterinary Authority; or
farmed cervidae in the herd:
showed no sign of bovine tuberculosis or lesions at ante- or post-mortem inspection for at least three consecutive years;
were over six weeks of age at the time of the first test and have shown a negative result to at least two tuberculin tests carried out at a minimum interval of six months; the first test should be performed at least six months following the slaughter of the last affected animal;
to maintain the free status, met one of the following conditions:
showed a negative result to an annual tuberculin test to ensure the continuing absence of bovine tuberculosis; or
showed a negative result to a tuberculin test every two years to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is not more than 1% of all herds in the country or zone during the last two years; or
showed a negative result to a tuberculin test every three years to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is not more than 0.2% of all herds in the country or zone during the last four years; or
showed a negative result to a tuberculin test every four years to ensure the continuing absence of bovine tuberculosis if the annual percentage of herds confirmed as infected with tuberculosis is not more than 0.1% of all herds in the country or zone during the last six years;
farmed cervidae introduced into the herd come from a herd free from bovine tuberculosis. This condition may be waived for animals which have been isolated for at least 90 days and which, prior to entry into the herd, were subjected to at least two tuberculin tests carried out at a six-month interval with negative results with the second tuberculin test performed during the 30 days prior to entry into the herd.
Recommendations for the importation of farmed cervidae for breeding or rearing
Veterinary Authorities of importing countries should require the presentation of an international veterinary certificate attesting that the animals:
showed no sign of bovine tuberculosis on the day of shipment;
originate from a herd free from bovine tuberculosis of farmed cervidae that is in a country, zone or compartment free from bovine tuberculosis of farmed cervidae; or
were subjected to the tuberculin test for bovine tuberculosis with negative results during the 30 days prior to shipment and come from a herd free from bovine tuberculosis of farmed cervidae; or
have been isolated for at least 90 days prior to entry into the herd including protection from contact with wildlife reservoirs of bovine tuberculosis and were subjected to at least two tuberculin tests carried out at a six-month interval with negative results with the second tuberculin test performed during the 30 days prior to entry into the herd.
Recommendations for the importation of farmed cervidae for slaughter
Veterinary Authorities of importing countries should require the presentation of an international veterinary certificate attesting that the animals:
showed no sign of bovine tuberculosis on the day of shipment;
originated from a herd free from bovine tuberculosis of farmed cervidae or were subjected to a tuberculin test for bovine tuberculosis with negative results during the 30 days prior to shipment;
were not being eliminated as part of an eradication programme against bovine tuberculosis.
Recommendations for the importation of semen of farmed cervidae
Veterinary Authorities of importing countries should require the presentation of an international veterinary certificate attesting that:
the donor animals showed no sign of bovine tuberculosis in any species on the day of collection of the semen; and either:
were kept in a herd free from bovine tuberculosis in a country, zone or compartment free from bovine tuberculosis of farmed cervidae, and which only accepts animals from free herds in a free country, zone or compartment; or
showed negative results to tuberculin tests carried out annually and were kept in a herd free from bovine tuberculosis;
the semen was collected, processed and stored in accordance with Chapters 4.5. and 4.6.
Recommendations for the importation of embryos/ova of farmed cervidae
Veterinary Authorities of importing countries should require the presentation of an international veterinary certificate attesting that:
the donor females and all other susceptible animals in the herd of origin showed no sign of bovine tuberculosis during the 24 hours prior to embryo collection; and either
originated from a herd free from bovine tuberculosis of farmed cervidae in a country, zone or compartment free from bovine tuberculosis; or
were kept in a herd free from bovine tuberculosis of farmed cervidae and were subjected to a tuberculin test for bovine tuberculosis with negative results during an isolation period of 30 days in the establishment of origin prior to collection;
the embryos/ova were collected, processed and stored in accordance with Chapters 4.7., 4.8. and 4.9., as relevant.
Recommendations for the importation of fresh meat and meat products of farmed cervidae
