Abstract: Inland waters are subject to more widespread biotic invasions than terrestrial ecosystems. During the last century, 756 aquatic species were introduced in Europe, frequently carrying new parasites for native fauna and humans. The consequences of such invasions are the loss of the invaders’ original parasites, the introduction of new parasites, or new intermediate hosts or vectors for existing parasites. Many parasites are water-borne and need aquatic species to complete their transmission cycles. The list of 100 of the World’s Worst Invasive Alien Species (Lowe et al., 2000) does not take into account human health problems, so a risk assessment of the consequences of invasive freshwater alien species requires more attention. Here we review the direct and indirect impacts of invasive freshwater alien species on human health. Direct impacts include the injuries or allergies and new contaminants (bacteria, toxins), and their role as intermediate hosts to human parasites. Indirect impacts include the effects of the chemicals needed to control these aliens, changes to ecosystem services making the invaded area less suitable for recreational human use and damage to cultivation/ aquaculture affecting human well-being in developing countries. A clear management response is urgently needed to halt their spread and reduce or minimize the risk of human and wildlife disease.
