Regulation 3(2)(b)
1. The milk shall be pasteurised, that is to say—
(a)retained at a temperature of not less than 62.8°C. and not more than 65.6°C. for at least thirty minutes and be immediately cooled to a temperature of not more than 10°C.; or
(b)retained at a temperature of not less than 71.7°C. for at least fifteen seconds and be immediately cooled to a temperature of not more than 10°C.; or
(c)retained at such temperature for such period as may be specified by the licensing authority with the approval of the Minister.
2. The whole of the apparatus in which the milk is pasteurised, including the cooler, shall be so constructed as to secure the protection of the milk from risk of atmospheric contamination by dust or otherwise.
3. When the milk is heated by a continuous-flow method and is pasteurised in accordance with—
(a)the provisions of sub-paragraph (b) of paragraph 1 of this Part of this Schedule; or
(b)a method approved by the Minister under sub-paragraph (c) of paragraph 1 hereof,
any apparatus in which the milk is to be heated to and maintained at a temperature of more than 65.6°C shall be provided with a device which shall automatically divert the flow of any milk which is not raised to the authorised temperature and automatically record each operation of the device. Such record shall be dated and preserved for a period of not less than three months.
4.—(1) Such indicating and recording thermometers as the local authority shall reasonably consider necessary shall be installed in suitable places in the apparatus in which the milk is pasteurised so as to indicate the temperatures at which the milk is retained and to which the milk is cooled.
(2) The records of recording thermometers shall be marked with graduations adequately spaced to give clear readings, and they shall be dated and preserved for a period of not less than three months.
5.—(1) A sample of the milk taken in accordance with Part I of Schedule 3 at the heat treatment establishment after pasteurisation shall satisfy the coliform test and the plate count test prescribed in Parts III and IV of that Schedule. The sample shall be deemed to satisfy the coliform test if the coliform count is less than 1 per ml. The sample shall be deemed to satisfy the plate count test if the plate count is not more than 30,000 per ml.
(2) A sample of the milk taken in accordance with Part I of Schedule 3 at the heat treatment establishment after pasteurisation shall after incubation for 5 days at 6°C. satisfy the plate count test prescribed in Part IV of that Schedule. The plated sample shall be incubated for 25 hours at 21 °C. The sample shall be deemed to satisfy the test if the plate count is not more than 100,000 per ml.
(3) A sample of milk taken in accordance with Part I of Schedule 3 after pasteurisation and before delivery to the consumer shall satisfy the methylene blue test prescribed in Part II of that Schedule and the phosphatase test prescribed in Part V of that Schedule. The methylene blue test shall be deemed to be satisfied if the milk fails to decolourise methylene blue in 30 minutes. The phosphatase test shall be deemed to be satisfied if the milk gives a reading of 10 μg or less of p—nitrophenol/ml of milk.
6.—(1) Milk which is pasteurised in bottles shall be supplied to the consumer in those bottles, and milk which is pasteurised in containers other than bottles shall be put into the containers in which it is to be supplied to the consumer at the premises at which it is pasteurised as soon as possible after pasteurisation.
(2) Every container in which the milk is transported, exposed or offered for sale shall be tightly closed and securely fastened with a cap or cover overlapping the lip of the container or in some other suitable manner approved by the local authority.
1.—(1) Where any bulk milk which has, for the purposes of transportation, been heat treated in another heat treatment establishment is to be subjected to pasteurisation in accordance with these Regulations, the requirements specified in the following sub-paragraphs shall apply.
(2) Milk shall not be accepted for further heat treatment unless it has a temperature not exceeding 6°C. on admission to the heat treatment establishment and is retained at such a temperature until pasteurisation.
(3) The milk processor shall check and record the temperature of the milk on admission to the heat treatment establishment and immediately before pasteurisation.
(4) For purposes of identifying sources of supply which exceed a plate count of 100,000 per ml., in order to exclude such milk from pasteurisation in accordance with these Regulations, the milk processor shall—
(a)before pasteurisation take a sample of the milk in accordance with Part I of Schedule 3;
(b)submit it to the plate count test prescribed in Part IV of that Schedule;
(c)record the result.
(5) The milk processor shall retain for a period of not less than three months the records made in compliance with sub-paragraphs (3) and (4) above.
1. In this Part of this Schedule, “bottle” means any container which has a capacity of not more than five litres and is of a type approved by the local authority.
2. The milk shall be sterilised, that is to say, filtered or clarified, and (except in the case of skimmed milk) homogenised, and thereafter heated to and maintained at such a temperature, not less than 100°C., for such a period as to ensure that it will comply with the turbidity test prescribed in Part VI of Schedule 3. The milk shall be heated as aforesaid—
(a)in bottles and in such a manner that on or before completion of the treatment the bottles shall be sealed with an airtight seal; or
(b)by a continuous-flow method.
3. Such thermometers and pressure gauges as the local authority shall reasonably consider necessary shall be installed in suitable places in the apparatus so as to indicate the temperature or pressure to which the milk is raised or subjected, as the case may be.
4.—(1) A sample of the milk taken in accordance with Part I of Schedule 3 at the heat treatment establishment after sterilisation shall after incubation for 15 days at 30 °C. satisfy the plate count test prescribed in Part IV of that Schedule. The sample shall be deemed to satisfy the plate count test if the plate count is not more than 10 per 0.1ml.
(2) A sample of the milk taken in accordance with Part I of Schedule 3 after sterilisation and before delivery to the consumer shall satisfy the turbidity test prescribed in Part VI of that Schedule. The sample shall be deemed to satisfy the test if it gives a filtrate showing no sign of turbidity.
1. Immediately after heating as aforesaid by a continuous-flow method the milk shall be put into the sterile containers in which it is to be supplied to the consumer. Such containers shall be filled and sealed at the premises at which the treatment has been carried out with such aseptic precautions as will ensure the protection of the milk from the risk of contamination.
2. The records of such recording thermometers as the local authority shall reasonably consider necessary to be installed in suitable places in the apparatus in which the milk is to be heated as aforesaid by a continuous-flow method shall be marked with graduations adequately spaced to give clear readings, and they shall be dated and preserved for a period of not less than three months.
3. Any apparatus in which the milk is to be heated as aforesaid by a continuous-flow method shall be provided with a device which shall automatically divert the flow of any milk which is not raised to the authorised temperature and automatically record each operation of the device.

4. Every container in which the milk heated as aforesaid by a continuous-flow method is transported, exposed or offered for sale shall be so closed and securely fastened that it is airtight.
1. The milk shall be treated by the ultra high temperature method, that is to say retained at a temperature of not less than 135°C. for not less than one second.
2. Any apparatus in which the milk is to be heated to and maintained at a temperature of not less than 135°C. shall be provided with a device which shall automatically divert the flow of any milk which is not raised to the authorised temperature and automatically record each operation of the device. Such record shall be dated and preserved for a period of not less than three months.
3.—(1) Such indicating and recording thermometers as the local authority shall reaonably consider necessary shall be installed in suitable places in the apparatus in which the milk is treated by the ultra high temperature method so as to indicate the temperatures to which the milk is heated.
(2) The records of recording thermometers shall be marked with graduations adequately spaced to give clear readings, and they shall be dated and preserved for a period of not less than three months.
4. A sample of the milk taken in accordance with Part I of Schedule 3 at the heat treatment establishment after treatment by the ultra high temperature method shall after incubation for 15 days at 30°C. satisfy the plate count test prescribed in Part IV of that Schedule. The sample shall be deemed to satisfy the plate count test if the plate count is not more than 10 per 0.1ml.
5.—(1) Milk which is treated by the ultra high temperature method shall immediately after such treatment be put into the sterile containers in which it is to be supplied to the consumer. Such containers shall be filled and sealed at the premises at which the treatment has been carried out with such aseptic precautions as will ensure the protection of the milk from risk of contamination.
(2) Every container in which milk treated by the ultra high temperature method is transported, exposed or offered for sale shall be so closed and securely fastened, either with a cap overlapping the lip of the container or in some other suitable manner approved by the licensing authority, that the container is airtight.
