Seroprevalence and economic impact of eradicating zoonotic brucellosis in Malaysia: A case study of Melaka state of Malaysia

Abstract

Aim: A study was carried out to elucidate the seroprevalence of brucellosis in small and large ruminants in Melaka state of Malaysia and estimate the economic impact of zoonotic brucellosis in Malaysia using available data. Materials and Methods: Data was collected during culling exercises by the Department of Veterinary Services of Malaysia as a result of surveillance using CFT as a confirmatory test for brucellosis. Results: The average compensation in 4 years per district of Melaka state was RM12248.875(USD 3874.75) and the total compensation paid in 4 years was RM146,986.50(USD45,865.24) with year 2009 having the highest compensation amount of RM58,914.40(USD18,383.48). The estimated total economic losses due to brucellosis stands at about RM200,607,946.80 (USD 62,926,060.84) in a year for the whole of Malaysia. The odds of brucellosis in large ruminants (cattle/buffaloes) was significantly 1.6 times more compared to small ruminants (goats/sheep) in Melaka (P<0.0001; C.I. 1.41, 1.81) during the 4 year period. Average 4 year total seroprevalence for brucellosis in Melaka was significantly higher in 2010 than previous years with a rate of 7.78 % (P<0.05; Phi=0.025). Mass importation of livestock may be contributing in complicating the brucellosis situation. Conclusion: Considering the economic importance of brucellosis and its epidemiological importance to public health more needs to be done to ensure successful eradication of the zoonotic disease in Malaysia.
