Section 785.581Â Product
Adulteration
All necessary precautions shall
be taken throughout the entire operation to prevent the adulteration of one
product with another (See Subpart D and E). The commingling of one type of
liquid or dry product with another shall be considered as an adulteration of
that product. This does not prohibit the standardization of like products or
the production of specific products for special uses, provided labeling
requirements are met (21 C.F.R. Part 133 and 135).
