The
control of major animal diseases has been tremendously successful
in enhancing animal production and the globalisation of trade in
animals and animal products. The higher health status of animals
achieved today, particularly in developed countries, has substantially
contributed to the economic productivity and prosperity of such
countries. It has also resulted in a readily available and reasonably
priced supply of high quality animal protein for human populations.
However, the enhanced standard of animal health has been accompanied
by a commensurate and ever increasing level of vulnerability to
the introduction or re-introduction of serious animal or zoonotic
diseases. Moreover, in modern animal husbandry practices, very large
numbers of animals are raised in close proximity. These factors
further amplify the vulnerability to disease introduction and transmission,
and have led to a global, almost paranoiac, fear of disease introduction
because of the repressive trade bans which continue to be imposed
at the mere suggestion of such an event. Such bans, whether justified
or not, result in profound economic consequences for affected trading
countries. This has made it almost impossible for decision-makers
to select any course of action other than a stamping-out
approach. Decades of experience have shown
that the stamping-out approach has been relatively effective and
successful for disease control and eradication from defined geographical
areas. It has, however, resulted in major hardships, economic losses,
environmental damage, negative societal reaction, producer distress,
concerns for animal welfare, the destruction of massive numbers
of animals and the loss of valuable animal protein.
In a parallel development, the World Organisation for Animal
Health (OIE: Office International des Epizooties) has established
guidelines for safe trade in animals and animal products, which
essentially are science-based procedures to identify and mitigate
disease risks. These guidelines are continually being developed
and updated by world experts using the latest scientific information
under the OIE process. When approved by the 169 member countries
of the OIE, these guidelines are published annually as the Terrestrial
animal health code. Nevertheless, despite efforts to maintain
the relevance of the Code, the resulting standards have not
always been uniformly adopted and implemented by the principal trading
nations. This too has resulted in significant hardships and increased
pressure to apply stamping out. Under certain
circumstances, as is the case with specific zoonotic diseases, stamping
out may be the only legitimate and effective approach that can be
applied. However, in many circumstances, stamping out is increasingly
becoming less well accepted, less appropriate, and may even become
prohibitive and unacceptable. Therefore, it has become
imperative to search for alternative approaches to mass animal destruction
and disposal for the control of animal diseases and to develop approaches
that effectively control animal diseases yet minimise the multiple
detrimental aspects of the mass animal destruction approach of stamping
out. The papers of this monograph display a variety of alternative
approaches and the rationale that led to them. Together, they underscore
the reasoning that justifies this search. Such
alternatives will only have a significant impact if they provide
legitimate approaches to decision-makers. These approaches must
guide the anticipation, prevention or mitigation of the catastrophic
consequences of animal diseases on human health, on the security
of the food supply, on the welfare of animals and on the economics
of the production and trade of animals and animal products.
Ideally, if such alternatives could be accepted on a national
scale, there is a possibility that they could be implemented on
an international scale. Such an achievement could enhance the well-being
of the global society by using, not destroying, high quality animal
protein at a time when a significant portion of the world population
is unable to obtain an adequate source of animal protein.
