So What's the Difference Between Sludge and USDA Organic Compost
Good for Whole Foods, but so what? USDA Organic farms are not supposed to be using bio-solids anyway. The only difference between bio-sludge and the compost being used on "USDA Organic" farms in California is that sludge is tested while the compost is not.
The mega USDA Organic farms in California (eg Earthbound Farms) are dependent on the use of tons of off-farm compost, per acre and are still being certified as 'USDA Organic" by the CCOF (in collusion with NOP) despite the fact that compost they are importing is proven to be contaminated with pesticides that are specifically not allowed for use on USDA Organic certified farms. Contrary to common beliefs, there generally is no testing of any of the products being used on USDA Organic farms in California. Unlike the compost being used on USDA Organic farms, with sludge you have a better idea of what's not in it. The official USDA AMS NOP position regarding contaminating of soil, water, and air on USDA Certified farming operations, at least in California is "We do not test." Here's a link to the official NOSB definition of "organic" as per the USDA:
