The EPA has published results from a nationwide survey of sewage treatment plants, important data regarding the safety of our food supply since wastewater byproducts end up in our farm fields. These byproducts, or "biosolids," are residue from wastewater plants, and include everything from nitrogen and phosphorous (common fertilizers) to toxic metals and pharmaceuticals, like antibiotics and zinc. More than half of the approximately 7 million metric tons of biosolids produced each year end up on farm fields as fertilizer. Government agencies have allowed this practice despite not knowing what constitutes sewage sludge and how it might impact humans, livestock, and the environment. Some important findings from the study, which surveyed 74 large treatment plants, include:
An EPA official says that "it's not appropriate at this point to speculate on signifciance of the results." The agency will likely complete risk assessments on 10 of the chemicals in the study. There are plenty of reasons to believe that these findings are more than significant, including a federal court decision last spring that ordered USDA to compensate a farmer for the death of hundreds of cows. The livestock died from slewage sludge poisoning. Source: Science

It's true what our moms said...we are what we eat. In fact, it's truer than they thought. What I eat doesn't just affect me anymore, it affects all of us.
Unfortunately, the story of food can sometimes be complicated. But envirovores help each other out...which is why this blog will be bringing you news, tips, and information about food and the environment every step of the way.
