A commercial feed is deemed to be adulterated:

(1)  If it bears or contains any poisonous or deleterious substance which may render it injurious to health; but in case the substance is not an added substance, the commercial feed shall not be considered adulterated under this subsection if the quantity of that substance in the commercial feed does not ordinarily render it injurious to health.

(2)  If it bears or contains any added poisonous, added deleterious, or added nonnutritive substance which is unsafe within the meaning of § 406 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 346), other than one which is:

(i)  A pesticide chemical in or on a raw agricultural commodity; or

(ii)  A food additive.

(3)  If it is, or it bears or contains any food additive which is unsafe within the meaning of § 409 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 348).

(4)  If it is a raw agricultural commodity and it bears or contains a pesticide chemical which is unsafe within the meaning of § 408(a) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 346a(a)). Where a pesticide chemical has been used in or on a raw agricultural commodity in conformity with an exemption granted or a tolerance prescribed under § 408 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 346a) and that raw agricultural commodity has been subject to processing such as canning, cooking, freezing, dehydrating, or milling, the residue of that pesticide chemical remaining in or on that processed feed is not deemed unsafe if that residue in or on the raw agricultural commodity has been removed to the extent possible in good manufacturing practice and the concentration of that residue in the processed feed is not greater than the tolerance prescribed for the raw agricultural commodity unless the feeding of that 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 § 408(a) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 346a(a)).

(5)  If it is, or it bears or contains any color additive which is unsafe within the meaning of § 706 of the Federal Food, Drug and Cosmetic Act (21 U.S.C. § 376).

(6)  If any valuable constituent has been in whole or in part omitted or abstracted from the feed or any less valuable substance substituted.

(7)  If its composition or quality falls below or differs from that which it is purported or is represented to possess by its labeling.

(8)  If 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 regulations promulgated by the director to assure that the drug meets the requirement of this chapter 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 those regulations, the director 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 (21 U.S.C. § 301 et seq.), unless he or she determines that they are not appropriate to the conditions which exist in this state.

(9)  If it contains viable weed seeds in amounts exceeding the limits which the director shall establish by rule or regulation.
