And what about industry? It has top capability and has demonstrated unrealized 
potential of service to the livestock industry, It wants, so far as our experience suggests, 
exactly what the grower wants. For different reasons, both genuinely want independent 
evaluations. Such research, moreover, canscarcely beinconflict with the responsibilities 
of regulatory agencies. We submit that this is a major and primary research obligation 
that cannot be sidestepped without disservice aliketo farmers, manufacturers, regulatory 
agencies, research organizations, and the public. It is simply a question of getting what is 
best for agriculture! 
There is, we sense, a growing consciousness ofthe necessity for unbiased evaluation 
before consumer use of chemicals, especially drugs. If true, this is most significant; it 
means that we shall inevitably proceed toward a better solution of the problem of 
chemicals in agriculture, If not true, the urgency of the job ahead to find this solution 
gives us little time. Agriculture will suffer without safe, efficient chemicals; and 
unbiased evaluation may be the only means of assuring such chemicals, It is unfortunate 
that current events have resulted in some curtailment of industrial endeavor in anti- 
parasitic chemicals. Present policies may serve less than they should, There is room 
for thought because the interests and welfare of all depends upon implicit trust in the 
unprejudiced findings of research, 
In this discussion, we have emphasized the importance of parasitism as a biological 
phenomenon, the economic significance of parasitic diseases of food animals, and our 
heavy reliance upon chemicals as adjuvants in their control; also the apparent safety of 
such chemicals and the urgency, as of today, of broadening our development and use of 
them. It has been equally emphasized that the answers to today’s problems, which now 
threaten further progress, are to be found largely in more knowledge about parasites 
and parasitism. Finally, there is need for unbiased evaluation of new agents as a solution 
to a difficult problem, as a service to all interests, and as a means of bolstering the 
confidence of all in the objectivity of research.
