Cocaine found in all 13 Brazilian sharpnose shark samples | WION Dispatch
Summary
TLDRIn a bizarre twist, Brazilian sharpnose sharks from Rio de Janeiro's waters tested positive for cocaine, with 13 out of 13 showing high levels in their livers and muscles. Scientists suspect the drug may have entered the water from illegal factories or drug users' waste. The cocaine could impair the sharks' eyesight and hunting abilities, potentially reducing their lifespan. Additionally, a 1985 incident saw a bear named Pablo Escobar die from a cocaine overdose. The environmental impact of cocaine is also concerning, as it can be toxic to various marine species, causing infertility and cellular damage.
Takeaways
- đ Brazilian sharpnose sharks have been found with high levels of cocaine in their livers and muscles.
- đ The cocaine in sharks is believed to have originated from Rio's sewage system, possibly from illegal factories or drug users' waste.
- đŠ Sharks consuming cocaine could face reduced life expectancy due to impaired eyesight and hunting skills.
- đ» The story of a bear named Pablo Escobar, who died after overdosing on cocaine dropped by drug smugglers, is mentioned as an example of wildlife affected by drugs.
- đ Cocaine is harmful to sharks, potentially causing infertility by disrupting the production of vitellogenin, which is crucial for egg yolk formation.
- đŠ The absence of yolk can lead to starvation for embryonic sharks, impacting their survival.
- đ The environmental impact of cocaine is not limited to sharks; it can also be toxic to mollusks, crustaceans, and fish.
- đ§Ș Lab studies have shown that environmentally realistic concentrations of cocaine can cause DNA fragmentation and cell death in marine life.
- đ° The findings are published in the 'Science of the Total Environment' journal, highlighting the broader implications of drug pollution in marine ecosystems.
- đ« The presence of cocaine in marine life underscores the need for better management of drug waste and its potential environmental consequences.

Q & A
What is the primary subject of the transcript?
-The transcript discusses sharks in the waters around the coast of Brazil testing positive for cocaine and the potential implications for their health and marine life.
How many Brazilian sharpnose sharks were tested for cocaine?
-Thirteen Brazilian sharpnose sharks were tested.
What were the results of the tests on the sharks?
-All thirteen sharks had high levels of cocaine in their livers and muscles.
What are some potential effects of cocaine on sharks?
-Cocaine can reduce sharks' life expectancy, damage their eyesight, affect their hunting skills, and disrupt the production of vitellogenin in their livers, which is essential for their eggs.
What are some speculated sources of the cocaine found in the sharks?
-The cocaine may have come from Rio's sewage system, illegal cocaine factories, or from the excrement of drug users through untreated sewage. It could also have been lost or abandoned in the sea by drug smugglers.
How does cocaine affect the reproduction of sharks?
-Cocaine can disrupt the production of vitellogenin in shark livers, which forms the yolk in their eggs. Without yolk, there is no food for the embryonic baby shark, potentially leading to infertility.
What was the fate of the bear known as 'Pablo Escobear'?
-The bear, a 175-pound black bear, died in 1985 after overdosing on cocaine that was dropped by a group of Colombian drug smugglers in the wilderness of Tennessee.
How does cocaine affect other marine life besides sharks?
-Cocaine can be toxic to mollusks, crustaceans, and bony fish. Environmentally realistic concentrations can cause various signs of damage, including DNA fragmentation and cell death.
Which journal published the study on the effects of cocaine on marine life?
-The study was published in the journal 'Science of the Total Environment.'
What is the main concern of scientists regarding the presence of cocaine in marine environments?
-Scientists are concerned that cocaine can harm marine life, reducing their life expectancy, affecting their reproductive health, and causing cellular damage, which can disrupt marine ecosystems.
Outlines
đ» America's 1985 Cocaine Bear and Brazil's Cocaine Sharks
The 1985 story of America's 'cocaine bear,' also known as Pablo Escobear, has a parallel in Brazil's 'cocaine sharks.' In Rio de Janeiro, 13 sharp nose sharks tested positive for cocaine. This discovery raises concerns about the sharks' health, including reduced life expectancy and impaired hunting skills. The bear died from a cocaine overdose after drug smugglers dropped their stash in Tennessee, whereas the sharks likely ingested the drug through Rio's sewage system or abandoned cocaine at sea.

Transcripts
it appears that America's 1985 cocaine
bear or the Pablo escoba story as it
eventually came to be known has found
its much not too far away enter Brazil's
cocaine sharks swimming in the waters
around the coast of Brazil have been
tested positive for cocaine as bizarre
as it may sound it is true scientists
have tested 13 Brazilian sharp nose
sharks taken from the Waters of Rio De
Janeiro
and well all the 13 shunks had high
levels of the recreational narcotic in
their livers and muscles scientists now
fear that it can reduce their life
expectancy with cocaine damaging their
eyesight and affecting their hunting
skills however Pablo escco met a much
worse fate in 1985 the 175b black bear
passed away after overdosing on cocaine
it was dropped by a group of Colombian
drug smugglers in the Wilderness in
Tennessee on to the central question how
did the Sharks end consuming cocaine in
the first place some marine biologists
opine that the drug likely came from
Rio's seage system they said that it may
have come from illegal cocaine factories
or from the ex excrement of drug users
through untreated seage meanwhile some
believe that the Sharks were feeding on
cocaine that was lost or abandoned in
the sea by drug smugglers cocaine is as
bad for sharks as it is for humans it
could lead to all kinds of problems
including infertility cocaine can
disrupt the production
of
vitellogenin in shark livers which forms
the York in their eggs absence of York
means no food for the embryonic baby
shark furthermore cocaine is not just
harmful for sharks but also the marine
life according to the study published in
the science of the total environment
Journal cocaine can be toxic to molases
Crustaceans and bonny fish lab studies
show that environmentally realistic
concentrations can cause various signs
of damage including DNA fragmentation
