# Fertilisers and Feeding Stuffs Act 1926, Schedule FIFTH: Deleterious Ingredients in Feeding Stuffs


(a) Salts soluble in water, if present in a feeding stuff in proportion likely to be injurious to the health of animals.
(b) All poisonous substances except those naturally present in the material or materials from which the feeding stuff is derived.
(c) Sand, silicious matter or other insoluble mineral matter not naturally associated with ingredients of the feeding stuff which do not fall within the scope of this Schedule, or which, even if naturally so associated, are present in greater proportion than the maximum that may be expected to be due to such natural association.
For the purposes of this paragraph the term " insoluble " shall imply insolubility in hydrochloric acid, as determined by a prescribed method; the term " natural association " shall be construed as applying to average commercial samples of the feeding material with which it may be claimed that a particular mineral ingredient is associated.
