Little danger, I guess. The eradication program introduces no new evolutionary pressure on worms' lavae living in water. Those filtered out or killed in their hosts are removed from the gene pool anyway. On the other hand, we may discover more such preexisting hosts, as dogs. A parasitic relationship that evolved over a much longer period than a few mere decades and evolving from a much larger population than the few individuals thought to remain in the wild.
