Inspections, certifications, or specification-type gradings, and other inspections which may be requested by the official plant and are in addition to the normal inspection requirements and functions for the processing, production, or certification for a wholesome egg product under this part, shall be made pursuant to the voluntary egg products inspection regulations (part 592 of this chapter).

(b) Any food manufacturing establishment or institution which uses any eggs that do not meet the requirements of 21 U.S.C. 1044(a)(1) in the preparation of any articles for human food shall be deemed to be a plant processing egg products requiring inspection under the regulations in this part.

(c) Any product which is prepared under inspection in an official plant shall be inspected in such plant as often as the inspector deems necessary in order to ascertain if the product is unadulterated, wholesome, properly labeled, and fit for human food at the time it leaves the plant. Upon any such inspection, if any product or portion thereof is found to be adulterated, unwholesome, or otherwise unfit for human food, such product or portion thereof shall be condemned and shall receive such treatment as provided in § 590.422.
