摘要

Harmless treatment of infective animal carcasses plays an important part in eliminating serious animal epidemics. This is because it contributes to weed out animal diseases of disease-affected areas. Traditional treatment methods, i.e. deep burying and burning, fermentation, oil refining, alkaline hydrolysis, and anaerobic digestion processes, may associate with hidden troubles on bio-security if they are not properly used. In this paper, the author discusses the advantages and disadvantages of various harmless treatment methods, which may contribute for the selection of harmless treatment method and reduce biological risk.
