TANKS AND TANKING.
Regulation 18.
All condemned carcasses, parts of carcasses, and meat food products shall be tanked as follows:
(a) After the lower opening of the tank has been securely sealed by an employee of the Department, and the condemned carcasses, parts, and meat food products are placed therein in his presence, the upper opening shall be likewise securely sealed by such employee, whose duty it shall be then to see that a sufficient force of steam is turned into the tank and maintained a sufficient length of time effectually to render the contents unfit for any edible product. Tanks for this purpose shall be so located or operated that the fumes and odors therefrom shall not pervade compartments in which carcasses are dressed or edible products prepared. Wire and lead seals are provided by the Department for sealing tanks.
(b) A sufficient quantity of coloring matter or other substance to be designated by the Department shall be used in connection with the tanking of all condemned carcasses, parts of carcasses, meats, and meat food products, to destroy them effectually for food purposes.
(c) The seals of tanks containing condemned meats or the tankage thereof shall be broken only by an employee of the Department.
(d) If an establishment where inspection is maintained fails to permit the treatment and tanking of condemned carcasses, parts of carcasses, meats, or meat food products, as required by these regulations, the inspector in charge shall report that fact to the Department, in order that inspection may be withdrawn from such establishment.
Regulation 19.
Any meats or meat food products condemned at establishments which have no facilities for tanking shall be treated as provided in Regulation 18, paragraph (b), and removed to an establishment indicated by the inspector in charge and there tanked and rendered under the supervision of an employee of the Department.

S. Suspect." The employee who affixes the tag shall report the number to the inspector in charge. This "U. S. Suspect" tag shall remain upon the animal until the preliminary post-mortem inspection at the time of slaughter. If no lesions of disease are then discovered, the "U. S. Suspect" tag shall be removed and forwarded to the inspector in charge, with a report that the carcass has been inspected and passed, and the carcass shall be labeled or stamped "U. S.
