CAN GMOS BE USED IN ORGANIC PRODUCTS?
The use of genetic engineering, or genetically modified
organisms (GMOs), is prohibited in organic products.
This means an organic farmer can’t plant GMO seeds,
an organic cow can’t eat GMO alfalfa or corn, and an
organic soup producer can’t use any GMO ingredients.

farmer’s organic system plan. This
written plan describes the substances and practices to
be used, including physical barriers to prevent contact
of organic crops with prohibited substances or the
products of “excluded methods” such as GMOs.

To meet the USDA organic regulations, farmers and
processors must show they aren’t using GMOs and that
they are protecting their products from contact with
prohibited substances from farm to table.

PREVENTION PRACTICES

Additionally, certifying agents conduct residue
testing to determine if these preventive practices are
adequate to avoid contact with substances such as
prohibited pesticides, antibiotics, and GMOs.

Organic operations implement preventive practices
based on site-specific risk factors, such as neighboring
conventional farms or shared farm equipment or
processing facilities. For example, farmers:

Plant their seeds early or late to avoid organic and
GMO crops flowering at the same time (which can
lead to cross-pollination).

Harvest crops prior to flowering or sign
cooperative agreements with neighboring farms
to avoid planting GMO crops next to organic ones.

Designate the edges of their land as a buffer zone
where the land is managed organically, but the
crops aren’t sold as organic.

Thoroughly clean any shared farm or processing
equipment to prevent unintended exposure to
GMOs or prohibited substances.

All of these measures are documented in the organic
National Organic Program | Agricultural Marketing Service

On-site inspections and records verify that farmers are
following their organic system plan.

Any certified organic operation found to use
prohibited substances or GMOs may face enforcement
actions, including loss of certification and financial
penalties. However, unlike many pesticides, there
aren’t specific tolerance levels in the USDA organic
regulations for GMOs.
As such, National Organic Program policy states that
trace amounts of GMOs don’t automatically mean the
farm is in violation of the USDA organic regulations. In
these cases, the certifying agent will investigate how
the inadvertent presence occurred and recommend
how it can be better prevented in the future.
For example, they may require a larger buffer zone or
more thorough cleaning of a shared grain mill.

CAN GMOS BE USED IN ORGANIC PRODUCTS (continued)?
Can you show me an example of
how this would work?
In the sketch below, the organic farmer has set up
several buffer zones to protect the integrity of her
organic crops from GMOs. Where her farm borders the
conventional farm, she has set aside an area which
she will farm organically (for example, she won’t apply
prohibited pesticides), but she won’t sell that land’s
crops as organic.
She has also posted “no spray” signs on the borders of
her property and has another buffer zone on the left
side to protect her farm from unintended substances
from the local road. A final buffer zone on the right
side of her property includes a row of trees to reduce
erosion and protect runoff into the bordering river.

How is USDA working to
further address this topic?
USDA supports all methods of agriculture production,
including organic, conventional, and biotechnology. To
help these different methods coexist better, USDA has
convened an Advisory Committee on Biotechnology
and 21st Century Agriculture (“AC21”). Organic
stakeholders are well-represented on AC21.
Consumers purchase organic products expecting
that they maintain their organic integrity from farm
to market, and USDA is committed to meeting these
expectations. No matter where it was grown, if a
product has the USDA Organic label on it, it wasn’t
produced with GMOs.
