Bovine spongiform encephalopathy: Development of the international and national control and surveillance legislation and an economical assessment of different scenarios of a future surveillance strategy in Austria
Dissertation, Vet. Med. Univ. Wien, pp. 276.
In its first part this paper aims at summarising national, European and international developments in respect of BSE during this period of time and at describing their effects on the legislation and the organisations involved. Not only on European level but also in Austria BSE led to political debate and structural and organisational changes in public veterinary services. The financial dimensions of comprehensive/nationwide BSE testing from 1.1.2001 and the introduction of the total meat and bone meal feeding ban in December 2000 have been described independently in separate chapters. The second part of the paper aims at comparing different surveillance scenarios. By using five models the effects on trade and the economical consequences resulting thereof have been assessed. Three surveillance models take into account the age of the animals to be tested. Animals from an age of 48 months or 60 months or animals born before 1.1.2005 have to be tested. Both alternative models have a risk based approach. One has been designed in such a way, that the requirements of type-B surveillance of the OIE could be met successfully; the other model represents a BSE-surveillance system that guarantees an infection rate of < 0.1 % with a 99 % safety margin. This question has been discussed with regard to OIE-compliance, number of tests to be performed and the resulting costs. The economical criteria underlying this mathematical model make the application of a surveillance model in accordance with the OIE-provisions the most economically sound option for Austria.
