The antibiotics found in Lake Erie waterways could contribute to the development of antibiotic-resistant bacteria — a rising global concern already.
From lead to arsenic to PFAS, what’s lurking in your tap water? Here’s what you need to know about water quality in the U.S.A variety of veterinary and human antibiotics were found consistently in water sampling in rivers and other tributaries flowing into western Lake Erie, new research has found.
"We have widespread livestock and increasing intensity of animals in this area," Johnson said as she presented the findings of her research May 23 in an online forum sponsored by"Antibiotics are water-soluble, so they run off easily," she said."They are also excreted in urine and feces, usually without really any changes, and then oftentimes manure is applied to land. So there's a pathway in which antibiotics can enter our environment fairly easily.
"This is what we were hoping that we would find, some relationship between compounds and what's in the watershed," she said. "Understanding how chronic low-level exposures affect any sort of natural community in an aquatic environment is difficult," Johnson said."I dug into that a little bit, and I haven't been able to find a lot of very clear evidence that the levels that we had would have had a very strong influence. But it is an antibiotic, and the harmful algal blooms are cyanobacteria.
The significant changes weren't exactly embraced by farmers at first, said Lisa Sanford, a veterinarian and co-owner of Sterner Veterinary Livestock Professionals in Westphalia, providing medical services for cattle and sheep throughout Clinton and surrounding counties.
