Sanitary, Processing, and Facility Requirements

§ 590.504 General operating procedures.

(a) Operations involving the processing, storing, and handling of eggs, ingredients, and egg products must be done in a sanitary manner.

(b)

(1) Eggs and egg products are subject to inspection in each official plant processing egg products for commerce.

(2) Any eggs and egg products not processed in accordance with the regulations in this part or part 591 or that are not otherwise fit for human food must be removed and segregated.

(c)

(1) All loss and inedible eggs or inedible egg products must be placed in a container clearly labeled “inedible” and containing a sufficient amount of denaturant or decharacterant, such as an FDA-approved color additive, suspended in the product. Eggs must be crushed and the substance dispersed through the product in amounts sufficient to give the product a distinctive appearance or odor. Inedible product may be held in containers clearly labeled “inedible” which do not contain a denaturant as long as such inedible product is properly packaged, labeled and segregated, and inventory controls are maintained. Such inedible product must be denatured or decharacterized before being shipped from a facility.

(2) Undenatured egg products or inedible egg products that are not decharacterized may be shipped from an official plant for industrial use or animal food, provided that it is properly packaged, labeled, and segregated, and inventory controls are maintained.

(d)

(1) Egg products must be processed to meet the standard set out in § 590.570.

(2) Unpasteurized or microbial pathogen-positive egg products may be shipped from an official plant to another official plant only when they are to be pasteurized, heat treated, or treated using other methods of treatment sufficient to produce egg products that are edible without additional preparation to achieve food safety in the second official plant. Official plants must maintain control of shipments of unpasteurized or microbial pathogen-positive egg products shipped from one official plant to another official plant for pasteurization or treatment. Shipping plants must seal such shipments in cars or trucks and label them in accordance with § 590.410(c). Containers of unpasteurized or microbial pathogen-positive egg product must be marked with the identification mark shown in Figure 2 of § 590.415.

(e) Inspection program personnel may allow an official plant to move egg products that have been sampled and analyzed for Salmonella, or for any other reason, before receiving the test results, if they do not suspect noncompliance by the plant with any provisions of this part. The official plant must maintain control of the products represented by the sample pending the results.
