Guidance

The Use of Kelp in Organic Livestock Feed

1. Purpose

This guidance establishes that kelp may be certified organic as a wild crop under 

7 CFR § 205.207 and must be certified organic if used as an ingredient in livestock feed per 

§ 205.237.

2. Scope

This guidance applies to all National Organic Program (NOP) certifying agents that certify kelp 

and certified organic operations that feed kelp to organic livestock. 

3. Background

Seaweeds are simple, saltwater-dwelling algae that can be referred to as aquatic plants. Most 

seaweeds or algae are green (about 1200 species), brown (about 1750 species), or red (about 

6000 species). Kelps are brown algae and are among the most common seaweeds consumed as 

food. Stationary kelps/seaweeds rooted via a holdfast are wild harvested from the intertidal 

(eulittoral zone) and deeper (sublittoral zone) waters throughout the world’s oceans.

The NOP recognized there is inconsistency in the use of organic kelp in organic livestock feed 

due to: 

1. lack of guidance regarding the certification of kelp as a wild crop, and 

2. confusion regarding the agricultural status of kelp.

The American Association of Feed Control Officials (AAFCO) has approved dried kelp from the

families Laminariaceae and Fucaceae for use as ingredients in livestock feed. Kelp is added to 

livestock feed to provide minerals and trace elements that are nutritionally important. On May 9, 

2011, the NOP clarified in the final guidance NOP 5022 - Wild Crop Harvesting that kelp can be 

certified organic. The NOP guidance is consistent with other international certification bodies 

that recognize that kelp may be certified organic. 

The NOP has received comments asserting that kelp is not agricultural and should be permitted 

only as a nonsynthetic, nonagricultural ingredient in organic livestock feed as per § 205.237(a).

This position implies that kelp should not have to be certified organic to be used in organic 

livestock feed. However, kelp is currently listed as an agricultural product under § 205.606 of 

the National List of Allowed and Prohibited Substances (National List). Because kelp is listed at 

§ 205.606, the NOP considers kelp an agricultural product and, therefore, kelp must be certified 

organic to be included in livestock feed.

4. Policy

4.1 Kelp is listed as an agricultural product under § 205.606.

4.2 Kelp is a wild crop that may be certified organic under the § 205.207 Wild-crop 

harvesting practice standard.

4.3 As required at § 205.237(a), all agricultural ingredients in organic livestock feed must be 

certified organic. Since kelp is an agricultural product used as an ingredient in livestock 

feed, kelp used in organic livestock feed must be certified organic. 

4.4 All kelp used in organic livestock feed should be certified organic by March 4, 2014. 

This timeframe provides a 12 month phase-in period after issuance of this final guidance 

for sources of kelp to become certified and commercially available as organic.

maintained under cultivation or other agricultural management.

§ 205.207 Wild-crop harvesting practice standard.

(a) A wild crop that is intended to be sold, labeled, or represented as organic must be harvested 

from a designated area that has had no prohibited substance, as set forth in § 205.105, applied 

to it for a period of 3 years immediately preceding the harvest of the wild crop.

(b) A wild crop must be harvested in a manner that ensures that such harvesting or gathering will 

not be destructive to the environment and will sustain the growth and production of the wild 

crop.
