'One Health' prerogative to illustrate environmental sink hypothesis of Accumulator Effectors

The incorporation of the integrative character to highlight intercollaborative discipline of 'One Health' was done by World Health Organization to illustrate it as "an approach to designing and implementing programmes, policies, legislation and research in which multiple sectors communicate and work together to achieve better public health outcomes". The worldwide efforts to incorporate modern trends in detection, diagnosis and medication to the development of treatment strategies to counter threat of emerging parasitic diseases have necessitated to adoption of workable measures in the interacting space of environment, livestock and public health. To root out disease elements evolving sustainable efforts gained significant recognition so that concerted attempts could succeed to eliminate the agents of pathogeny and put severe restriction on their prevalence. The recent spurt of invasive parasitism into the freshwater riverine ecosystem of Ganges at Prayagraj by alien parasitic species of Anisakidae from Arabian Sea has triggered newer danger of zoonotic diseases into hitherto unaffected aquatic systems. The migratory avian visitors could well be a cause of transfer of unwarranted species from marine environment. Simultaneously, the human interventions to promote alien invaders due particularly to man-made alterations in the aquatic environment provided an opportunity to focus on serious one health event. The deposition of iron from the ambient environment on to the tissues of brain was detected to be linked with moderate drinking, and that resulted into cognitive decline. The recent reports of iron deposition in aquatic fishery resources through helminth parasites as 'environmental sink' have raised hopes to exploit beneficial uses of pathogens, through which parasites like, Rotundocollarette capoori (Yadav, Kapoor & Malhotra) drain in heavy metals, viz. Hg, Pb, Fe etc., as accumulator effectors, from even the tissues of the host fish to enhance its survivability.
