A new study finds that sharks and rays harbor several harmful bacteria, some resistant to antibiotics, raising concerns over their impact on public health.
Shark s and rays - not the first thing that often comes to one’s mind when it comes to staples on a menu. Yet, they are frequently consumed in many coastal communities such as along the coast of Rio de Janeiro, Brazil ! But although these two species are a dietary staple, they is a notable lack of research on the bacterial risks associated with these marine species .
Led by Dr. Maíra Duarte Cardoso of Fundação Instituto de Pesca do Estado do Rio de Janeiro, the team began by isolating bacteria from the cloacal swabs of several sampled elasmobranchs. The bacteria were cultured, and thus began the identification process, which involved biochemical assays, antimicrobial susceptibility testing, and Polymerase Chain Reaction assays.
With the high consumption rates of elasmobranchs in Brazil, especially in coastal communities, the potential for zoonotic transmission of bacteria cannot be ignored. Public health authorities and researchers have been alerted to the discovery of pathogenic and antibiotic-resistant bacteria in this sun-drenched country, but the warning should be heeded wherever these species are consumed.Our community is about connecting people through open and thoughtful conversations.
