    (2) Milk shipped from the farm in cans shall not have a raw milk bacteria count of more than one million bacteria per mL.

    (D) Whenever the producer's raw milk bacteria count exceeds the standards in paragraph (C) of this rule, the producer shall be notified of the excessive bacteria count.

    (E) Whenever two of the last four bacteria counts exceed the bacteria standard as stated in paragraph (C) of this rule, the director shall send a written warning notice to the producer. The notice shall be in effect so long as two of the last four consecutive samples exceed the bacterial standard.

If this sample also exceeds the bacteria standard as established in paragraph (C) of this rule, the producer license or registration shall be suspended until satisfactory compliance is obtained. Shipment may be resumed and the producer license or registration reinstated by the director when an additional sample of the producer raw milk is tested and found satisfactory. The producer license or registration shall remain in a warning status as long as two of the last four bacteria counts exceed the standard. The director shall suspend the producer license or registration immediately for at least seven days, in accordance with section 917.22 of the Revised Code, whenever three of the last five bacteria counts within any twelve month period exceed the standard.
