(i) Protective coverings shall be used for the product in the plant and as it is distributed from the plant, as will afford adequate protection for the product against contamination by any foreign substance (including, but not being limited to, dust, dirt, and insects), considering the means intended to be employed in transporting the product from the plant.

§ 54.244 Temperatures and cooling and freezing procedures.

Temperatures and procedures which are necessary for cooling and freezing of domestic rabbits in accordance with sound commercial practice shall be maintained in the coolers and freezers, and chilling temperatures and procedures shall also be in accordance with sound commercial practice.

(a) Cooling. Immediately after evisceration and washing of the carcass, it shall be placed in a cooling tank containing running cold tap water to remove the animal heat from the carcass. Carcasses shall not be allowed to remain in the cooling tank for longer than one hour.

(b) Air chilling. Immediately after the initial water chilling, the carcasses shall be placed in cooling racks and thereupon placed in a refrigerated cooler with moderate air movements and a temperature which will reduce the internal temperature of the carcasses to from 36° F. to 40° F., both inclusive, within 24 hours.

(c) Freezing. (1) When ready-tocook domestic rabbits are packaged in bulk or shipping containers, the carcasses should be individually wrapped or packaged in water-vapor resistant cartons or the containers should be lined with heavy water-vapor resistant paper so as to assure adequate overlapping of the lining to completely surround the carcasses and to permit unsealed closure or sealing in such a manner that watervapor loss from the product is considerably retarded or prevented. The rabbit carcasses should receive an initial rapid freezing under such packaging, temperature, air circulation, and stacking conditions which will result in freezing the carcasses solid in less than 48 hours.

(2) Frozen ready-to-cook rabbits shall be held under conditions which will maintain the product in a solidly frozen state with temperature maintained as constant as possible.

(d) Refrigeration. Immediately after packaging, all ready-to-cook domestic rabbits, other than those which are shipped from the plant in a refrigerated carrier, should be moved into the freezer, except that a period not exceeding 72 hours will be permitted for transportation and temporary holding before placing in the freezer provided such rabbits are held at not above 36° F.

§ 54.245 Vermin.

Every practicable precaution shall be taken to exclude flies, rats, mice, and other vermin from the official plant. Dogs, cats, and other pets shall be excluded from rooms where edible products are processed, handled, or stored.

§ 54.246 Exclusion of diseased persons. No person affected with any communicable disease (including, but not being limited to, tuberculosis) in a transmissible stage shall be permitted in any room or compartment where exposed or unpacked edible products are prepared, processed, or otherwise handled.

[blocks in formation]

For the purpose of §§ 54.260 to 54.262, the classes of ready-to-cook domestic I rabbits are fryer or young rabbit and roaster or mature rabbit.

§ 54.261 Fryer or young rabbit.

A fryer or young rabbit is a young I domestic rabbit carcass weighing not less than 11⁄2 pounds and rarely more than 31⁄2 pounds processed from a rabbit usually less than 12 weeks of age. The flesh of a fryer or young rabbit is tender and fine grained and of a bright pearly pink color.

§ 54.262 Roaster or mature rabbit.

A roaster or mature rabbit is a mature or old domestic rabbit carcass of any

weight, but usually over 4 pounds processed from a rabbit usually 8 months of age or older. The flesh of a roaster or mature rabbit is more firm and coarse grained, and the muscle fiber is slightly darker in color and less tender and the fat may be more creamy in color than that of a fryer or young rabbit.

FORMS OF OFFICIAL IDENTIFICATION

§ 54.280 Forms of official identification. The forms prescribed in §§ 54.280 to 54.282 are subject to the requirements of §§ 54.60 to 54.63, Identifying and Marking Products.

§ 54.281 Form of grade mark.

The grade mark approved for use pursuant to § 54.61 on a graded product shall be contained within a shield of the form and design indicated in the example in Figure 1. The information which is required in such mark shall be: (a) The letters "USDA," (b) the appropriate U.S. Grade of the product. The information within the shield shall be printed

[ocr errors]

in a light color on a dark field. In addition, a term such as "Federal-State Graded" or "Government Graded" may be used adjacent to but not within the shield design grade mark (in a form similar to that illustrated in Figure 2). The class of the domestic rabbits shall be shown on the label which bears the grade mark if it is not shown prominently elsewhere on the packaging material. The appropriate designation "young,' "mature" or "old" may be used as a prefix to the words "domestic rabbit" in lieu of the class name. When the grade mark is applied to an individual carcass which is not individually packaged and labeled, the information with respect to the class of the domestic rabbits shall be included in the same label which bears the grade mark and the plant number or the firm name and address shall also be included on the label which bears the grade mark.
