Okla. Stat. tit. 2, § 2-8-41.7: Adulteration

A commercial feed shall be adulterated if:

1. a. it contains any poisonous or deleterious substance

which may render it injurious to health. If the

substance is not an added substance, the commercial

feed shall not be considered adulterated under this

subsection if the quantity of the substance in the

commercial feed does not ordinarily render it

injurious to health when utilized according to label

and/or labeling directions, or

b. it contains any added poisonous, added deleterious, or

added nonnutritive substance which is unsafe within

the meaning of Section 406 of the Federal Food, Drug,

and Cosmetic Act other than one which is:

(1) a pesticide chemical in or on a raw agricultural

commodity; or

(2) a food additive, or

c. it is, or contains, any food additive which is unsafe

within the meaning of Section 409 of the Federal Food,

Drug, and Cosmetic Act, or

d. it is a raw agricultural commodity and it bears or

contains a pesticide chemical which is unsafe within

the meaning of Section 408(a) of the Federal Food,

Drug, and Cosmetic Act. Provided, that where a

pesticide chemical has been used in or on a raw

agricultural commodity pursuant to an exemption or a

tolerance under Section 408 of the Federal Food, Drug,

and Cosmetic Act and the raw agricultural commodity has

been subjected to processing similar to canning,

cooking, freezing, dehydrating, or milling, the residue

of the pesticide chemical remaining in or on the

processed feed shall not be deemed unsafe if:

(1) the residue has been removed to the extent

possible in good manufacturing practice, and

(2) the concentration of the residue in the processed

feed is not greater than the tolerance prescribed for

the raw agricultural commodity unless the feeding of

the processed feed will result or is likely to result

in a pesticide residue in the edible product of the

animal, which is unsafe within the meaning of Section

408(a) of the Federal Food, Drug, and Cosmetic Act, or

e. it is or contains any color additive which is unsafe

within the meaning of Section 706 of the Federal Food,

Drug, and Cosmetic Act;

2. Any valuable constituent has been in whole or in part

omitted or abstracted or any less valuable substance substituted;

3. Its composition or quality falls below or differs from that

which it is purported or is represented to possess by its labeling;

4. It contains a drug and the methods used in or the facilities

or controls used for its manufacture, processing, or packaging do

not conform to current good manufacturing practice rules promulgated

by the State Board of Agriculture to assure that the drug meets the

requirement of this subarticle as to safety and has the identity and

strength and meets the quality and purity characteristics which it

purports or is represented to possess. In promulgating the rules,

the Board shall adopt the current good manufacturing practice

regulations for medicated feed premixes and for medicated feeds

established under authority of the Federal Food, Drug, and Cosmetic

Act, unless the Board determines that they are not appropriate to

the conditions which exist in this state; or

5. If it contains viable weed seeds in amounts exceeding the

limits the Board shall establish.
