Yes, food is grown in sewage waste and that's a big problem
You may not realize it but some foods you eat may have been grown in
soil containing toxic sewage wastes. Labeling is not required.
In 2019, about 60 percent of sewage sludge from 16,000 wastewater processing facilities in more than 160 U.S. cities has been spread on our soils - farmland and gardens, as well as schoolyards and lawns.
The U.S. Environmental Protect Agency (EPA) allows this use of sewage
waste, claiming it has beneficial use because it contains properties
similar to fertilizer - certain heavy metals, phosphorus and nitrates -
that could enhance soil conditions.
The agency does not require testing for other chemicals in the sewage waste. Yet, millions of tons of sewage are processed annually and the waste can contain upward of 90,000 chemicals plus and an array of pathogens, including mixtures of lead, mercury, arsenic, thallium, PCBs, PFAS, highly complex, superbugs, mutagens, pesticides, microplastics, radioactive wastes, pharmaceuticals, personal care products, steroids, flame retardants, dioxins, and/or their combinations.
