Gamma-Linolenic Acid Safflower Oil

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA, we, or Agency) is

fatty acids in dry food for adult cats in the maintenance life stage. 
This action is in response to a food additive petition filed by Arcadia 
Biosciences, Inc.

SUPPLEMENTARY INFORMATION: 

I. Background

    In a document published in the Federal Register of September 14, 
2017 (82 FR 43197), FDA announced that we had filed a food additive 
petition (animal use) (FAP 2302) submitted by Arcadia Biosciences. 
Inc., 202 Cousteau Pl., Suite 200, Davis, CA 95618. The petition 
proposed that the regulations for food additives permitted in feed and 
drinking water of animals be amended to provide for the safe use of GLA 
safflower oil as a source of omega-6 fatty acids in dry food for adult 
cats in the maintenance life stage.
    The petition for the safe use of GLA safflower oil as a source of 
omega-6 fatty acids in dry food for adult cats in the maintenance life 
stage (FAP 2302) indicated that the concentration of gamma-linolenic 
acid was between 350 and 450 milligrams (mg) gamma-linolenic acid per 
gram of the additive or the safflower oil blend. A previous petition 
(FAP 2275) that provided for the safe use of GLA safflower oil as a 
source of omega-6 fatty acids in dry food for adult dogs in the 
maintenance life stage indicated that the concentration of gamma-
linolenic acid was between 400 and 450 mg gamma-linolenic acid per gram 
of the additive or the safflower oil blend (82 FR 38595, August 15, 
2017).
    In amending Sec.  573.492 (21 CFR 573.492) to allow for the safe 
use of GLA safflower oil in dry food for adult cats, the current 
allowable concentration

[[Page 6675]]

range for gamma-linolenic acid in the additive or the safflower oil 
blend was amended to incorporate the broader range supported by FAP 
2302. This does not adversely alter the technical effect from use of 
the additive in adult maintenance dog food because provisions in the 
August 15, 2017, rule (82 FR 38597), revised in paragraph (b)(2) of 
this rule, specify that adjustments must be made for differing 
concentrations of gamma-linolenic acid to meet other specified 
parameters.

II. Conclusion

    FDA concludes that the data establish the safety and utility of GLA 
safflower oil as a source of omega-6 fatty acids in dry food for adult 
cats in the maintenance life stage and that the food additive 
regulations should be amended as set forth in this document. This is 
not a significant regulatory action subject to Executive Order 12866.

III. Public Disclosure

    In accordance with Sec.  571.1(h) (21 CFR 571.1(h)), the petition 
and documents we considered and relied upon in reaching our decision to 
approve the petition will be made available for public disclosure (see 
FOR FURTHER INFORMATION CONTACT). As provided in Sec.  571.1(h), we 
will delete from the documents any materials that are not available for 
public disclosure.

IV. Analysis of Environmental Impact

    The Agency has determined under 21 CFR 25.32(r) that this action is 
of a type that does not individually or cumulatively have a significant 
effect on the human environment. Therefore, neither an environmental 
assessment nor an environmental impact statement is required.

V. Objections and Hearing Requests

    Any person who will be adversely affected by this regulation may 
file with the Dockets Management Staff (see ADDRESSES) either 
electronic or written objections. Each objection shall be separately 
numbered, and each numbered objection shall specify with particularity 
the provision of the regulation to which objection is made and the 
grounds for the objection. Each numbered objection on which a hearing 
is requested shall specifically so state. Failure to request a hearing 
for any particular objection shall constitute a waiver of the right to 
a hearing on that objection. Each numbered objection for which a 
hearing is requested shall include a detailed description and analysis 
of the specific factual information intended to be presented in support 
of the objection in the event that a hearing is held. Failure to 
include such a description and analysis for any particular objection 
shall constitute a waiver of the right to a hearing on the objection.

    Authority:  21 U.S.C. 321, 342, 348.

2. Revise Sec.  573.492 to read as follows:


Sec.  573.492  Gamma-linolenic acid safflower oil.

    The food additive, gamma-linolenic acid safflower oil, may be 
safely used in animal food as a source of gamma-linolenic acid and 
other omega-6 fatty acids in accordance with the following conditions:
    (a) The additive is the oil obtained from whole seeds and/or 
partially dehulled seeds of a Carthamus tinctorius L. safflower 
Centennial variety genetically engineered to express the delta-6-
desaturase gene from Saprolegnia diclina Humphrey. The 453 amino acid, 
delta-6-desaturase enzyme converts the fatty acid linoleic acid to 
gamma-linolenic acid (all-cis-6,9,12-octadecatrienoic acid) during seed 
development.
    (1) The additive obtained from the seeds of the genetically 
engineered safflower Centennial variety may be blended with oil 
obtained from seeds of non-engineered oleic acid safflower varieties in 
order to meet the specifications required for the additive or the blend 
in paragraph (a)(2) of this section.
    (2) The additive or a safflower oil blend containing the additive 
for use in animal food meets the following specifications:
    (i) Crude fat content of the additive or the safflower oil blend is 
not less than 99.5 percent.
    (ii) Gamma-linolenic acid content is between 350 and 450 milligrams 
(mg) gamma-linolenic acid per gram of the additive or the safflower oil 
blend.
    (iii) Total content of stearidonic acid and cis, cis-6,9-
octadecadienoic acid in the additive or the safflower oil blend must 
not exceed a total of 0.3 percent.
    (b) Addition of the additive, or the safflower oil blend, to 
complete dry adult maintenance dog food must meet the following:
    (1) Addition of the additive or the safflower oil blend cannot 
provide more than 36 mg gamma-linolenic acid per kilogram body weight 
of the dog per day in more than 86 mg of the additive or the safflower 
oil blend. This maximum addition rate of the additive, or the safflower 
oil blend, is 0.3 percent of a complete dry adult maintenance dog food 
containing 3,600 kilocalories of metabolizable energy per kilogram of 
food as-fed.
    (2) Adjustments must be made for differing concentrations of gamma-
linolenic acid and for dog food formulas of different caloric density 
and/or that are fed to specific weights, breeds, or dogs of different 
activity levels to meet the requirements of this paragraph.
    (c) Addition of the additive, or the safflower oil blend, to 
complete dry adult maintenance cat food must meet the following:
    (1) Addition of the additive or the safflower oil blend cannot 
provide more than 33 mg gamma-linolenic acid per kilogram body weight 
of the cat per day in more than 79 mg of the additive or the safflower 
oil blend. This maximum addition rate of the additive, or the safflower 
oil blend, is 0.5 percent of a complete dry adult maintenance cat food 
containing 4,000 kilocalories of metabolizable energy per kilogram of 
food as-fed.
    (2) Adjustments must be made for differing concentrations of gamma-
linolenic acid and for cat food formulas of different caloric density 
and/or that are fed to specific weights, breeds, or cats of different 
activity levels to meet the requirements of this paragraph.
    (d) To assure safe use of the additive, in addition to other 
information required by the Federal Food, Drug, and Cosmetic Act, the 
label and labeling of the additive shall bear the following:
    (1) The name of the additive, gamma-linolenic acid safflower oil, 
or GLA safflower oil;
    (2) A guarantee for the minimum content of gamma-linolenic acid; 
and
    (3) Adequate directions for use such that the finished animal food 
complies with the provisions of paragraphs (b) and (c) of this section.
