Part 1540.0570 - REUSE OF WATER

Inspectors may permit the reuse of water in vapor lines leading from deodorizers used in the preparation of lard and similar edible products and in equipment used for the chilling of canned products after retorting, provided the reuse is for the identical original purpose and the following precautions are taken to protect the water that is reused:

A. All pipe lines, reservoirs, tanks, cooling towers, and like equipment employed in handling the reused water are so constructed and installed as to facilitate their cleaning inspection.

B. Complete draining and disposal of the reused water, effective cleaning of the equipment, and renewal with fresh, potable water is accomplished at such intervals as may be necessary to assure an acceptable supply of water for the purpose intended.

C. Effective chlorination (not less than approximately one part per million of residual chlorine at any point within the cooling system) of the reused water utilized for cooling canned product is maintained but with the understanding that chlorination alone is not to be relied upon entirely or to be accepted in lieu of the requirements listed in items A and B.
