Abstract
Aim To identify why “test and slaughter policy” for eradication
of brucellosis did not significantly reduce the prevalence
in sheep and goats in Macedonia.
Method Coverage of sampled vs expected number of
sheep and goats, absolute number of positive animals,
prevalence, frequency distribution, and classes of disease
prevalence were retrospectively analyzed at the village
level for 2004-2006. A comparative analysis of the disease
prevalence in the investigated villages was also performed.
The percentage of slaughtered animals was analyzed for
2000-2006.
Results We found differences between the expected and
actual number of sampled animals, which were related to
the type of livestock breeding. Traditionally maintained
flocks and migratory flocks were considered to be responsible
for the transmission of the disease. The absolute
number of positive animals and the number of infected
vs non-infected holdings did not decrease over the study
period. Most of the villages had between 1 and 10 positive
animals. Between 2000 and 2006, 55% of the positive
animals were slaughtered, 41% in 2001 and up to 79% in
2002. Moreover, in 2005 and 2006, 34% and 53% of sheep
and goats were found to be positive at the slaughter line,
respectively, demonstrating that only 21%-23% of the infected
animals were correctly removed from the herds.
Conclusion Based on the findings of this study, Macedonia
changed its control strategy from “test and slaughter”
to a vaccination policy for sheep and goats in 2008.
