household chlorine (bleach) is acceptable only if its accompanying
labeling allows for the use in dairy operations and is available at the
farm.) It is also important to use only acceptable sanitizer in the milking
operation.

Appendix F of the PMO specifically provides directions for use of
chemicals on non-porous food contact surfaces.

Sanitizers approved by the EPA for use on non-porous food contact
surfaces and which comply with Section 178.1010 of the Code of
Federal Regulations (CFR) are acceptable for use in sanitizing milk
contact surfaces. The CFR list sanitizer chemical types, strengths and
limitations under Subpart B-Substances utilized to control the Growth of
Microorganisms.

4. Finally, never follow the sanitizing operation with a clear water
rinse. This will remove the sanitizing residual and negate the purpose
of sanitizing the milk equipment.

5. Although it may seem like sound reasoning to leave sanitizing solutions
in the milk system between milkings, this practice, if used on a regular
basis could be harmful to the milk equipment. Rubber gaskets and
other surfaces may deteriorate or discolor upon prolonged exposure to
certain chemicals and chlorine chemicals are corrosive to stainless
surfaces.
