The final test results on the suspected BSE case have come back as an isolated case of “classical” BSE in a single animal, according to the Department of Agriculture, Food and the Marine.
Following all the protocols, the Department have identified all animals potentially exposed to the BSE agent that caused this incident, the animals who were born and reared on the birth-farm one year either side of the birth of the positive animal, and her progeny have been slaughtered and destroyed. They have been excluded from the food and feed chains, as well as tested.
The epidemiological investigation has confirmed that:
- All 63 cohort animals and 4 progeny slaughtered and disposed of have tested negative for BSE.
- The confirmed the case is an isolated case in a single animal.
- Both the dam and grand dam of the infected animal tested negative for BSE at slaughter, and therefore vertical transmission is not considered to be a factor in this case.
- Whilst the grand-dam of the positive animal was imported, this is not of any significance in epidemiological terms.
- No concerns arise regarding the integrity of the commercial feed supply chain or the effectiveness of the feed control systems.
- Test results from feed currently on the farm are also negative.
A diminishing number of such cases have been identified in Ireland and in other countries over the years.
These results are now being advised to the EU Commission and to the OIE. It is expected that the OIE will reassign ‘controlled risk’ status to Ireland, recognising the robust control systems in place which identified this once-off case and which will continue to underpin the safe trade in products from Ireland. The control system that has brought BSE under control is still in place, to protect human and animal health so it is deemed to be effective by the OIE.
1. Negligible risk status – the confirmation that this is case of classical BSE in a domestic animal which is less than 11 years old, means that Ireland no longer meets the parameters set out in the OIE code necessary for a country to be recognised as a country with negligible risk for BSE.
2. Controlled risk status – Ireland is recognised for its effective application of a set of effective controls and provides a basis for the safe trade in animals and products.
3. Controls in place
- A ban on the feeding of meat and bone meal to ruminants.
- Effective rendering processes.
- Systematic testing of feed supplies.
- Active and passive animal level surveillance and testing for the disease.
- Ante-mortem checks conducted by veterinarians on all animals prior to slaughter to ensure that only healthy animals enter the food chain.
- The removal and destruction, on a precautionary basis, of certain specified risk materials from slaughtered animals.
4. BSE does not transfer horizontally from animal to animal – no risk to other animals arises from this case animal.
