Brazil is a major consumer market for cocaine in South America and believed to be a significant contributor to coastal water contamination.
Female sharks had higher concentrations of cocaine than males.
Impact on sharks and other marine life is unclear, but previous studies show high levels of cocaine residue can cause toxicological effects.
Origins of the cocaine remain unknown, possibly from illegal labs or drug users' excrement or traffickers losing/dumping it at sea.
Thirteen sharpnose sharks tested positive for cocaine and its metabolite in Rio de Janeiro, Brazil.
In recent findings, scientists have reported that thirteen sharpnose sharks, caught off the coast of Rio de Janeiro, Brazil, tested positive for cocaine. The study conducted by the Oswaldo Cruz Foundation marks the first investigation into cocaine and benzoylecgonine detection in free-range sharks. All 13 sharks tested positive for cocaine and its primary metabolite, with female sharks having higher concentrations than males.
The origins of the cocaine in the sharks remain a mystery. Possible sources include illegal labs or drug users' excrement, as well as traffickers losing or dumping cocaine at sea. Brazil, being a major consumer market for cocaine in South America, is believed to be a significant contributor to the contamination of coastal waters.
The impact of cocaine on sharks and other marine life is still unclear. Previous studies have shown that high levels of cocaine residue can cause serious toxicological effects in animals such as brown mussels, oysters, and eels. However, more research is necessary to determine the full extent of the harm caused by cocaine contamination in sharks and other marine species.
The discovery of cocaine in sharks highlights the urgent need for further investigation into how illicit drugs enter coastal waters and impact marine life. The study calls for researchers to investigate how cocaine arrives in Rio de Janeiro's coastal waters, as well as the potential consequences for marine ecosystems.
Thirteen sharpnose sharks caught off the coast of Rio de Janeiro, Brazil tested positive for cocaine.
Cocaine residues were found to be 100 times higher in the sharks than in other marine animals.
The origin of the cocaine in the sharks is unknown, but possibilities include it falling into the sea during transshipment or being dumped by smugglers attempting to evade authorities. Another possibility is that it entered the sea through sewage discharges.
Brazil does not produce large amounts of cocaine but is a major exporter, with powerful street gangs such as the First Capital Command (PCC) sending tonnes of the drug in shipping containers to Europe.
Accuracy
Cocaine could potentially pass from the sharks to humans if consumed as part of the Brazilian diet.

The article contains a few informal fallacies and an appeal to authority. It uses inflammatory rhetoric by describing the high levels of cocaine in sharks as 'testing positive for cocaine' and '100 times higher than had been found in other marine animals'. This is sensationalist language rather than an accurate scientific description. Additionally, the article quotes Enrico Mendes Saggioro making a claim about the possibility of drug residues passing from fish to humans without providing counter-arguments or evidence. The author also uses inflammatory rhetoric when stating that 'cocaine is being widely traded and moved in Brazil', which could be interpreted as an accusation against the Brazilian government without evidence.
The sharks ‘high levels’ of cocaine are described as “testing positive for cocaine”. This is sensationalist language rather than an accurate scientific description.
Enrico Mendes Saggioro says, “ocaine residues could possibly pass from the fish to humans.” The article does not present counter-arguments or evidence for this claim.
The author states that “ocaine is being widely traded and moved in Brazil”, implying government negligence without providing evidence.
