The Certified Naturally Grown Livestock Standards (PDF) are based on the USDA National Organic Program standards with a few significant modifications, as noted below.
We clarified and strengthened the standards for living conditions and access to pasture. The organic rules were worded in such a way that agribusiness growers got away with their animals never actually going outside their whole lives. If that describes you, then you should stick to Organic, but if your animals are primarily pasture raised, then we'd love to have you.
Another very significant change is in feed requirements. The feed must be grown according to CNG standards - without synthetic fertililzers, pesticides, herbicides or GMO seeds - but it does not have to be certified organic or certified naturally grown feed. We are trying to encourage local systems, and when you can find a local source that's grown right, even if not certified, we think you should have the option to use it. Please note: to meet CNG standards it is NOT enough that the feed contains no medications. (That is important, but not sufficient.) If you're not sure whether your feed would qualify, please review the CNG Feed Supplier Declaration which we require from CNG livestock producers.
A final change has to do with how we handle the origin of livestock requirement outlined in 205.236. The USDA apparently does allow non-organic livestock to be purchased and brought into an organic operation, but we are trying to be more explicit about it, and allow variances only under specific conditions when there is no organic or naturally grown source of the sought-after livestock (see 205.236(a)(3)). We allow this variance because we believe in increasing the number of farmers who choose to get involved and to grow naturally or organically. We want to minimize hurdles to taking on these practices, so long as removing these hurdles doesnt compromise the integrity of the on-farm growing practices.
CNG's modifications to the NOP standards are indicated in italics in the CNG standards below. The paragraph numbers here correlate with the numbers in the USDA Organic standards. Definitions or referrals to paragraphs not found on this page can be clarified by going straight to the above listed USDA website. We ask all farmers who seek certification to review the National List of Allowed and Prohibited Substances, referenced in section 205.105.
