Investigadores found cocaine in all shrimp samples tested in a rural area of eastern England. In addition to the narcotic product, crustaceans had ketamine, a substance primarily used to induce and maintain anesthesia.
Scientists at King’s College London, in collaboration with the University of Suffolk, were the authors of the discovery that is surprising everything and everyone after having been sampled from more than 15 locations in Suffolk County, UK.
The study, published in Environment International, looked at the levels of various “micro-pollutants” in freshwater prawns.
Thomas Miller, the lead author of the study, added that “concentrations were low” but that compounds “may pose a risk to wildlife”.
Contamination of water by drug waste is a growing problem, with insecticide residues and drugs entering the system. Leon Barron, also an investigator, cataloged this regular occurrence of illicit drugs in wildlife as “surprising.” “We could expect to see them in urban areas like London, but not in smaller, more rural basins,” he added.
