PART 96_RESTRICTION OF IMPORTATIONS OF FOREIGN ANIMAL CASINGS OFFERED 
FOR ENTRY INTO THE UNITED STATES--Table of Contents
 
Sec. 96.13  Uncertified casings; disinfection with hydrochloric acid.

    Foreign animal casings offered for importation into the United 
States without certification may be disinfected, as prescribed in this 
section, under the supervision of an APHIS inspector for use as food 
containers, as an alternative for foreign certification.
    (a) Disinfect the casings in a solution made as follows: Dissolve 90 
pounds common salt in 100 gallons water and mix. Add 2\3/4\ gallons 
(10.35 liters) C. P. hydrochloric acid containing not less than 35 
percent actual HCl and mix throughly. The finished solution must contain 
not less than 1 percent actual hydrochloric acid.
    (b) Containers of the disinfectant solution may be either of wood or 
of metal, but the interior surfaces must be protected by means of an 
acid resist ant coating.
    (c) Not more than 175 pounds casings shall be treated with each 100 
gallons of the solution. After the treatment of 175 pounds of casings, 
or at the end of the day if less than 175 pounds of casings are 
disinfected in any one day, the solution shall be discarded unless means 
are provided for accurately determining the loss of strength. In event 
means for accurately determining loss of strength are provided it will 
be permissible to restore the strength of the solution with fresh acid 
and use it repeatedly.
    (d) Shake as much of the adherent salt as possible from the casings 
and weigh them. Bundles must be separated but individual hanks need not 
be untied. Place the casings in the disinfecting solution a few hanks at 
a time with vigorous agitation to insure the fullest possible contact of 
the solution with them. Then keep the casings completely submerged in 
the solution for not less than three-fourths of an hour.
    (e) Remove the casings from the solution, rinse them with water, and 
place them in a solution containing 8\1/2\ pounds of sodium bicarbonate 
in each 100 gallons of water. 100 gallons of this solution is sufficient 
for 175 pounds of casings. Keep the casings in this solution for 30 
minutes, moving them about frequently and vigorously so as to insure 
complete contact of the solution with the casings. After this 
neutralization, remove the casings from the sodium bicarbonate solution 
and wash them to remove the excess of bicarbonate.
