To assure a safe, wholesome finished product, changes in processing methods and procedures as may be required by the Director shall be effectuated as soon as practicable. All processed products which are not manufactured or prepared in accordance with the requirements contained in §§ 260.96 to 260.104 or are unwholesome or otherwise not fit for human food shall be removed and segregated prior to any further processing operation.
(c) Official establishments operating under Federal inspection should have an effective quality control program as appropriate for the nature of the products and processing operations.

(e) The methods and procedures employed in the receiving, segregating, handling, transporting, and processing of ingredients in official estab lishment(s) shall be adequate to result in a satisfactory processed product. Such methods and procedures include, but are not limited to, the following requirements:
(1) Containers, utensils, pans, and buckets used for the storage or transporting of partially processed food ingredients shall not be nested unless rewashed and sanitized before each use;
(2) Containers which are used for holding partially processed food ingredients shall not be stacked in such manner as to permit contamination of the partially processed food ingredients;
