Of the 300+ products we produce, four products once contained biosolids. Since we have moved to register all of our products to be compliant with the USDA’s National Organic Program (NOP), none of our products contain bio-solids/sewage sludge in any form. Bio-solids/sewage sludge is a prohibited ingredient under USDA’s National Organic Program. All Kellogg Garden Organics and G&B Organics branded products are approved by the California Department of Food and Ag Organic Input Materials (OIM) program and listed with the Organic Materials Review Institute (OMRI). No product with an OIM seal or OMRI seal on the bag may contain bio-solids/sewage sludge.
