All raw milk storage tanks or silos installed after the effective date of this act that are not cleaned daily shall be provided with an approved recording thermometer and shall be cleaned and sanitized at least every 72 hours except as approved by the director in writing, on a case-by-case basis.\n\nEnsure that all product contact surfaces of separators are free from rust and pits and, if practicable, are of stainless steel or other equally noncorrosive metals.\n\nEnsure that each batch pasteurizer has a temperature indicator and recording device and conforms to sanitary standards and complies with the following, as applicable:\nt as approved by the director in writing, on a case-by-case basis.\n\nEnsure that all product contact surfaces of separators are free from rust and pits and, if practicable, are of stainless steel or other equally noncorrosive metals.\n\nEnsure that each batch pasteurizer has a temperature indicator and recording device and conforms to sanitary standards and complies with the following, as applicable:\n\nHas an air-space indicating thermometer that is accurate within 1.0 degree Fahrenheit (0.5 degree Celsius) for the proper temperature range at least 1 inch above the surface of the products pasteurized in a vat to ensure that foam in the vat or air above the product pasteurized receives the minimum temperature treatment required by the department.\n\nHas a recording thermometer that is accurate within 1.0 degree Fahrenheit (0.5 degree Celsius) for the proper temperature range.\n\nHas surface coolers equipped with leak-proof gaskets and connections and with hinged or removable covers for the protection of the product and has edges of the covers that are designed to divert condensate on non-product-contact surfaces away from product contact surfaces. The use of surface coolers will be allowed only with specific written approval of the director on a case-by-case basis.\n\nUse recording thermometers accurate within 2.0 degrees Fahrenheit (1.0 degree Celsius) to record holding and cooling time.\n\nProvides long-stem or equally acceptable indicating thermometers that are accurate within 0.5 degree Fahrenheit (0.25 degree Celsius) for the applicable temperature range, for checking the temperature of pasteurization and cooling of products in vats and checking the accuracy of recording thermometers.\n\nEnsure that high-temperature, short-time pasteurization equipment is tested and sealed by the department upon installation and quarterly thereafter and complies with sanitary standards and with the following, as applicable:\n\nIn accordance with manufacturer recommendations, has in each high-temperature, short-time pasteurizer a short-stem or equally acceptable indicating thermometer that is accurate within 0.5 degree Fahrenheit (0.25 degree Celsius) for the applicable temperature range, to be used for checking the accuracy of recording thermometers.\n\nHas in each storage tank for which the department requires a temperature reading an indicating thermometer that is accurate within 2.0 degrees Fahrenheit (1.0 degree Celsius).\n\nProvides that all new or replacement plate-type heat exchangers meet sanitary standards, all gaskets are tight and kept in good repair, and plates are opened at sufficiently frequent intervals to determine if the equipment is clean and in satisfactory condition.\n\nEnsure compliance with each of the following:\n\nInternal return tubular heat exchangers meet sanitary standards.\n\nPumps used for milk and dairy products are of the sanitary type and constructed to meet sanitary standards.\n\nUnless a pump is specifically designed for effective cleaning in place, pumps are dismantled and cleaned after use.\n\nHomogenizers and high-pressure pumps of the plunger type comply with sanitary standards.\n\nNew equipment and replacements, including all plastic parts and rubber and rubberlike materials for parts and gaskets having product contact surfaces, meet sanitary standards.\n\nA vacuum chamber, if used, is made of stainless steel or other equally noncorrosive material; is constructed to facilitate cleaning with all product contact surfaces accessible for inspection; is equipped with a vacuum breaker and a check valve at the product discharge line; uses only steam that meets the sanitary standards; regulates incoming steam supply by an automatic valve that cuts off the steam supply if the flow diversion valve of the high-temperature short-time pasteurizer is not in the forward flow position; and uses only condensers equipped with a water level control and an automatic safety shutoff valve.\nker and a check valve at the product discharge line; uses only steam that meets the sanitary standards; regulates incoming steam supply by an automatic valve that cuts off the steam supply if the flow diversion valve of the high-temperature short-time pasteurizer is not in the forward flow position; and uses only condensers equipped with a water level control and an automatic safety shutoff valve.\n\nBulk storage and distribution equipment in dairy plants for handling liquid sweetening agents, edible oils, or other ingredients consists of suitable metals, alloys, or other materials that will withstand corrosive action by the ingredients and the equipment and ingredients are protected from contamination. Pipelines containing liquid sweetening agents and liquid chocolate remain flooded with the ingredient to prevent mold growth or may be dismantled and washed.\n\nEnsure that the plant is provided with adequate ventilation, that is acceptable to the director, to minimize possible product contamination with condensation, dust, and odors.","path":["MI Code","Chapter 288","Act Act-267-of-2001"],"source_url":"https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-288-701","current_through":"2026-08-14","vintage":"open-us-law v2026.08, retrieved 2026-09-14","retrieved_at":"2026-09-14T18:32:31Z","sha256":"75813439b48e93b397757665b278abe835ef71b146a199bfa3e1de953e931eb1","source_id":"us-mi","stale":false,"prev":"us-mi/mich.-comp.-laws-288.700","next":"us-mi/mich.-comp.-laws-288.702"},"notice":"GroundRules: Original legal text.
