- (b) No railroad car, truck, boat, aircraft or other means of conveyance from which poultry or other animals affected with an infectious, contagious or communicable disease of livestock or poultry, other than those specified in [§ 71.4(b)](/cfr/9/71.4.md?p=b), have been unloaded shall thereafter be used in connection with the interstate movement of animals, including poultry, or be moved interstate until it has been cleaned and disinfected by the final carrier under the supervision of an APHIS or State representative or an accredited veterinarian in accordance with §§ [71.7](/cfr/9/71.7.md) and [71.10 through 71.12](/cfr/9/71.10..71.12.md).
- (c) If APHIS supervision or other supervision as required by paragraph [(a)](#a) or [(b)](#b) of this section or proper cleaning and disinfecting facilities are not available at the point where the animals are unloaded, upon permission first received from the Animal and Plant Health Inspection Service, the means of conveyance may be forwarded empty to a point at which such supervision and facilities are available, and there be cleaned and disinfected under supervision in accordance with §§ [71.7](/cfr/9/71.7.md) and [71.10 through 71.12](/cfr/9/71.10..71.12.md).

# §71.7. Means of conveyance, facilities, premises, and cages and other equipment; methods of cleaning and disinfecting.

# §71.10. Permitted disinfectants.

- (a) Disinfectants permitted for use on cars, boats, and other vehicles, premises, and cages and other equipment are as follows:
  - (1) “Cresylic disinfectant” in the proportion of at least 4 fluid ounces to 1 gallon of water.
  - (2) Liquefied phenol (U.S.P. strength 87 percent phenol) in the proportion of at least 6 fluid ounces to 1 gallon of water.
  - (3) Chlorinated lime (U.S.P. strength, 30 percent available chlorine) in the proportion of 1 pound to 3 gallons of water.
  - (4) Sodium hydroxide (Lye) prepared in a fresh solution in the proportion of not less than 1 pound avoirdupois of sodium hydroxide of not less than 95 percent purity to 6 gallons of water, or one 13 1/2 ounce can to 5 gallons of water. Due to the extreme caustic nature of sodium hydroxide solution, precautionary measures such as the wearing of rubber gloves, boots, raincoat, and goggles should be observed. An acid solution such as vinegar shall be kept readily available in case any of the sodium hydroxide solution should come in contact with the body.
  - (5) Disinfectants which are registered under the Federal Insecticide, Fungicide, and Rodenticide Act ([7 U.S.C. 135](/usc/7/135.md) et seq.), with tuberculocidal claims, as disinfectants for general use, may be used for the purpose of this part in accordance with directions on the labels accepted in connection with their registration. However, disinfectants which fall in this category are not permitted for use in outbreaks of foreign animal diseases unless in specific cases such use is approved in advance by the Administrator.
- (b) **The use of “cresylic disinfectant” is permitted subject to the following conditions—**
  - (1) The manufacturer thereof shall have obtained specific permission from APHIS for the use of his products in official disinfection. To obtain such permission manufacturers shall first submit a sample of at least 8 ounces for examination, together with a statement of the formula employed and a guaranty that the product will be maintained of a quality uniform with the sample submitted.
  - (2) To prevent confusion, the product of each manufacturer and distributor shall bear a distinctive trade name or brand, together with the name of the manufacturer or distributor.
  - (3) The product shall at all times conform to specifications for composition and performance issued by the Administrator.

# §71.11. Cresylic disinfectant as permitted disinfectant; specifications.


The following specifications will be employed for determining the suitability of cresylic disinfectant for use under the provisions of [§ 71.10(b)(3)](/cfr/9/71.10.md?p=b-3):

- (a) The product shall remain a uniform liquid when held at 0 °C. (32 °F.) for 3 hours (chill test).
- (b) The product shall dissolve completely in 30 parts of distilled water at 25 °C. (77 °F.) within 2 minutes (solution-rate test), producing a solution entirely free from globules and not more than faintly opalescent (solubility-degree test).
- (c) The product shall contain not more than 25 percent of inert ingredients (water and glycerin), not more excess alkali than the equivalent of 0.5 percent of sodium hydroxide, and not less than 21 percent of soap exclusive of water, glycerin, and excess alkali.
- (d) The product shall contain not less than 50 percent and not more than 53 percent of total phenols. It shall contain less than 5 percent of benzophenol (C 6H 5OH).
- (e) The methods of determining compliance with the specifications in [paragraphs (a) to (d)](#a..d) of this section will be those described in United States Department of Agriculture Bulletin 1308, Chemical and Physical Methods for the Control of Saponified Cresol Solutions, so far as they are applicable.
- (f) Any suitable glyceride, fat acid, or resin acid may be used in preparing the soap, but not all are suitable nor are all grades of a single product equally suitable, Also various grades of commercial cresylic acid differ in suitability. Therefore, manufacturers are cautioned to prepare a trial laboratory batch from every set of ingredients and to prove its conformity with paragraphs [(a)](#a) and [(b)](#b) of this section, before proceeding with manufacture on a factory scale.
