By their terms, sections 13(a)(5) and 13(b)(4) provide no exemption
with respect to operations performed on any products other than the
aquatic products named in these subsections (see Sec. 784.107).
Accordingly, neither of the exemptions is applicable to the making of
any commodities from ingredients only part of which consist of such
aquatic products, if a substantial amount of other products is contained
in the commodity so produced (compare Walling v. Bridgeman-Russell Co.,
6 Labor Cases 61, 422, 2 WH Cases 785 (D. Minn.) and Miller v.
Litchfield Creamery Co., 11 Labor Cases 63, 274, 5 WH Cases 1039 (N.D.
Ind.), with Mitchell v. Trade Winds, Inc., 289 F. 2d 278). Thus, the
first processing, canning, or processing of codfish cakes, clam chowder,
dog food, crab cakes, or livestock food containing aquatic products is
often not exempt within the meaning of the relevant exemptions.
