"Trust and Bartlett (1974) pointed out that the bacteria that are shipped
with fishes are provided with a liquid menstruum with added nutrients in the
form of fish feed, surfaces for colonization, heated water, and aeration,
which are perfect conditions for the culture of the pathogens. A wide
variety of bacterial species capable of causing disease in humans are able
to grow on commercial fish diets as the sole source of nutrients (Trust and
Money 1972). Moreover, some of these fish diets also contain potential
pathogens of humans (Trust and Money 1972). Other studies revealed that
human pathogens such as Vibrio cholerae, V. parahaemolyticus, Erysipelothrix
rhusiopathiae, and Leptospira icterohemorrhagiae can survive and multiply in
the gut, mucus, and tissues of fishes (Janssen 1970)."
