Sharks in Rio de Janeiro have tested positive for cocaine, raising concerns about the drug’s impact on marine life and humans.

Brazilian scientists discovered cocaine in sharpnose sharks caught off the beach in Rio de Janeiro. The Guardian reported this.

The researchers found that all 13 sharks caught by the fishermen tested positive for the drug. Scientists are looking to show how the use of illegal drugs harms marine animals.

How cocaine gets into the sharks’ bodies remains unknown. One theory is that the drugs enter the sea through sewage or through containers of drugs bound for Europe.

Another concern is that sharpnose shark is a common part of the Brazilian diet, increasing the risk of cocaine residue reaching humans.

“We do not know how much this factor affects a person, and it should be the subject of future research but in any case, it is a warning,” said Enrico Mendez Sagioro, a researcher at the Oswaldo Cruz Institute.

It was previously reported that a rare pelagic largemouth shark was caught in Zanzibar waters.
