Sec. 73.10  Permitted dips; substances allowed.

    (a) The dips at present permitted by the Department for the 
treatment, as required in this part, of cattle affected with or exposed 
to scabies, are as follows:
    (1) Lime-sulphur dip, other than proprietary brands thereof, made in 
the proportion of 12 pounds of unslaked lime (or 16 pounds of commercial 
hydrated lime, not airslaked lime) and 24 pounds of flowers of sulphur 
or sulphur

flour to 100 gallons of water; or a specifically permitted proprietary 
brand of lime-sulphur dip.
    (2) Dips made from specifically permitted proprietary brand 
emulsions of toxaphene and maintained throughout the dipping operation 
at a concentration between 0.50 and 0.60 percent toxaphene. Animals 
treated by such dips should not be slaughtered for food purposes until 
the expiration of such period as may be required under the Federal Meat 
Inspection Act (21 U.S.C., Supp. III, 601 et seq.). The length of this 
required period shall be specified on each certificate issued by the 
APHIS inspector or State inspector who supervises the dipping with such 
dips.
    (3) Approved proprietary brands of coumaphos (Co-Ral 
[reg]), 25 percent wettable powder or flowable form used at a 
concentration of 0.30 percent.
    (4) Approved proprietary brands of organophosphorous insecticides 
(Prolate [reg]) used at a concentration of 0.15 percent to 
0.25 percent.
    (b) The dipping bath for lime-sulphur dip must be used at a 
temperature of 95 [deg] to 105 [deg]F., and must be maintained through 
the dipping operation at a concentration of not less than 2 percent of 
``sulphide sulphur'', as indicated by the field test for lime-sulphur 
dipping baths approved by the APHIS.\1\ The dipping bath for toxaphene 
emulsions must be kept within a temperature range of 40[deg]-80 [deg]F., 
and at a concentration between 0.50 and 0.60 percent throughout the 
dipping operations. \2\
---------------------------------------------------------------------------

    \1\ The field test for lime-sulphur dipping baths is described in 
U.S. Department of Agriculture Bulletin 163, for sale by the 
Superintendent of Documents, Government Printing Office, Washington, 
D.C. 20402, at 5 cents a copy.
    \2\ Care must be exercised in dipping animals and in maintaining the 
bath at the standard concentration. Detailed instructions will be issued 
for the guidance of employees who may be called upon to use them in the 
scabies eradication program.
---------------------------------------------------------------------------

    (c) Proprietary brands of lime-sulphur or toxaphene dips may be used 
in official dipping only after specific permission therefor has been 
granted by the Administrator. Before a dip will be specifically approved 
as a permitted dip for the eradication of scabies in cattle, the APHIS 
\3\ will require that the product be registered under the provisions of 
the Federal Insecticide, Fungicide and Rodenticide Act, as amended (7 
U.S.C. 135 et seq.); that is efficacy and stability have been 
demonstrated; that trials have been conducted to determine that its 
concentration can be maintained and that under actual filed conditions 
the dipping of cattle in a bath of definite strength will effectually 
eradicate scabies infection without injury to the animals dipped.
---------------------------------------------------------------------------

    \3\ Information as to the names of such dips may be obtained from 
the APHIS or a APHIS inspector.
