Over a decade of scientific research and studies have repeatedly shown that crops fertilized with properly treated biosolids are safe for consumption. An example of research supporting this conclusion comes from the US National Academy of Sciences who reviewed public health concerns relating to biosolids and concluded that: “the use of these materials in the production of crops for human consumption when practiced in accordance with existing federal guidelines and regulations, presents negligible risk to the consumer, to crop production and to the environment.” Advanced processes and products, such as the pathogen-free, organically rich, Class A (EQ) LysteGro® biofertilizer are setting even higher standards in beneficial re-use.
