There can be NO excuse for this. WTF were they thinking?
Sewage sludge can contain disease-causing microbes, synthetic chemicals, and heavy metals that can cause acute and chronic disease, finds the "Smart Guide on Sludge Use in Food Production" by IATP's Marie Kulick. Many of these contaminants can persist in soil for centuries and can enter the food system through crops grown on sludge-treated land, as well as through food animals that graze on sludge-treated land.
Currently, there is no labeling requirement for food produced on land treated with sewage sludge, and consumers may find it difficult to know if they are using a sludge-based fertilizer product. IATP developed the "Smart Guide" and companion resources to help consumers make informed food and fertilizer choices.
"Given the high contaminant content of sludge, it makes no sense to allow the use of sludge on agricultural land or home gardens," says Kulick. "This practice poses an unnecessary health risk, particularly when there are safer alternatives available."
