§ 59.216d. Temperature-recording charts, equipment tests and examinations.
(a) Temperature recording charts. All temperature recording charts shall be preserved for a period of 3 months. The use of such charts shall not exceed the time limit for which they are designed. Overlapping of recorded data shall be a violation of this subsection. The following information shall be entered on the chart as applicable.
(1) Batch pasteurizers. Information for batch pasteurizers shall be as follows:
(i) Date.
(ii) Number or location of recorder when more than one is used.
(iii) Extent of holding period, including filling and emptying times, when required.
(iv) Reading of airspace thermometer within the holding period at a given time or reference point as indicated on the chart.
(v) Reading of indicating thermometer within the holding period at a given time or reference point as indicated on the chart.
(vi) Quarterly, the initials of the regulatory agency opposite the required readings of the indicating thermometer and airspace thermometer.
(vii) Quarterly, the time accuracy of the recorder, as determined by the Department.
(viii) Amount and name of pasteurized milk or milk product represented by each batch or run on the chart.
(ix) Record of unusual occurrences.
(x) Signature or initials of operator.
(xi) Name of milk plant.
(2) High-temperature, short-time pasteurizers. Recording thermometer charts shall contain all the information specified in paragraph (1) except paragraph (1)(iii) and (iv), and reference to airspace thermometers in paragraph (1)(vi) shall include the following:
(i) A record of the time during which the flow-diversion device is in the forward-flow position.
(ii) The cut-in and cut-out milk temperatures recorded daily by the operator at the beginning of the run and initialed quarterly by the Department.
(b) Equipment tests and examinations. The Department will perform the indicated tests on the following instruments and devices in accordance with Appendix I of the PMO.
