§ 480. Sterilization Process.
The following chemical sterilization processes are hereby established in reference to Sections 33519 and 33763 of the Food and Agricultural Code:
(c) Chlorine solutions when used by the flowing or immersion method must always have a strength in excess of 50 p.p.m. (parts per million) of active or available chlorine. When used as a fogging or paste method of application the concentration of active or available chlorine in the sterilizing solution must exceed 250 p.p.m. (parts per million).
(e) Iodine compounds when used by the flowing or immersion method must always have a concentration of active ingredient in excess of 12.5 p.p.m. (parts per million). If used as a fogging method, the concentration of the active ingredient must always be in excess of 25 p.p.m. (parts per million). Iodine compounds used as a combination detergent sterilizer must have the concentration of the active sterilizing ingredient doubled over the amount when used as a sterilizing agent.

Milking machine rubber parts may be sterilized by filling with or completely immersing in a 0.5 percent caustic (lye) solution and so kept between milkings. Before the rubber parts are used the lye solution must be drained and the rubber parts rinsed.
(g) All equipment to be treated with solutions of any sterilizing agent must first be thoroughly cleaned and rinsed before sterilizing except when such sterilizing agent is used in combination with a detergent as a detergent sterilizer. After sterilizing with a detergent sterilizer, the equipment must be allowed to drain and be rinsed with water, treated by heat or a chemical sterilizing agent to assure freedom from viable pathogenic or otherwise harmful microorganisms before use.
