Weird science: Scientists can’t figure out why Shrimp is testing positive for cocaine

Every shrimp scientists studied tested positive for cocaine as well as banned pesticides Newsweek reports.

The results of shrimp testing positive for cocaine will be published in Environmental International. In the study, shrimp samples in July 2018 from 15 sites on the east coast of England, U.K. — Gipping, Alde, Deben, Stour and Waveney.

Scientists found U.K. banned substances, fenuron, ketamine (animal tranquilizer; also used as a party drug) and Tramadol (antidepressant) in all of their shrimp samples.

While there is no word on why this is happening it has attracted attention from the public due to ongoing issues of climate change and microplastic pollution.

The study’s lead, Dr. Thomas Miller said “Although concentrations were low, we were able to identify compounds that might be of concern to the environment and crucially, which might pose a risk to wildlife.”

The potential effect for these drugs are low but it is an issue that is widespread across the globe. Washington Department of Fish and Wildlife found oxycodone in shellfish.
