Chemicals in sewage sludge fertilizer used on farms pose cancer risk, EPA says

Environmental Protection Agency officials warn of toxic PFAS found in sewage often spread on pasture

Harmful chemicals in sewage sludge spread on pasture as fertilizer pose a risk to people who regularly consume milk, beef and other products from those farms, in some cases raising cancer risk several orders of magnitude" above what the Environmental Protection Agency considers acceptable, federal officials announced on Tuesday.

When cities and towns treat sewage, they separate the liquids from the solids and treat the liquid. The solids need to be disposed of and can make a nutrient-rich sludge often spread on farm fields. The agency now says those solids often contain toxic, lasting PFAS that treatment plants cannot effectively remove. When people eat or drink foods containing these forever" chemicals, the compounds accumulate in the body and can cause kidney, prostate and testicular cancer. They harm the immune system and childhood development.
