Scary: a dozen sharks test positive for cocaine
As part of a study shared by the Oswaldo Cruz Foundation (in Latin America), a team of scientists carried out analyses on a dozen wild sharpnosed sharks. The results showed that all the sharks - 13 in all - had been exposed to cocaine.
A high concentration of the drug was detected in sharpnose sharks off the coast of Brazil. In particular, experts found a concentration up to 100 times higher than already reported for other marine creatures, as told by the media outlet 20 Minutes.
While the scientists confirmed that these substances were indeed transiting “in the raw sewage from rivers and urban canals that flow into this coastal region”, this exposure in the sharks' natural habitat is also thought to be linked to the transport of cocaine by sea.
