Is there a toxic or other adverse action of the petitioned substance or its breakdown products?
Corn steep liquor should not have any toxic or other adverse actions. The components of corn steep liquor are readily metabolized and utilized by micro-organisms as an energy source. Because corn steep liquor is a nutrient source, algal growth is possible, if corn steep liquor reaches bodies of water in concentrated form. However, the manufacturing of corn steep liquor is a controlled process and given the current uses of corn steep liquor, one would not expect large quantities of corn steep liquor being released to bodies of water.
Is there undesirable persistence or concentration of the petitioned substance or its breakdown products in the environment?
The components of corn steep liquor are readily metabolized and utilized by micro-organisms as energy sources, therefore, corn steep liquor would not persist and concentrate in the natural environment.
Are there detrimental physiological effects on soil, organisms, crops, or livestock by using the petitioned substance?
There is no information available to indicate that using corn steep liquor has detrimental physiological effects on soil, organisms, crops, or livestock. Because it is rich in nutrients, it can be applied to soils as a fertilizer or soil conditioner and it has been successfully fed to livestock for many years.
Is there any harmful effect on human health by using the petitioned substance?
Corn steep liquor has no harmful effects on human health. The components of corn steep liquor are used as ingredients in foods for human consumption (proteins, amino acids, carbohydrates, vitamins, and minerals). Corn steep liquor has been successfully fed to livestock for many years without any adverse effects on human health.
