PURPOSE OF THE UNIT STANDARD 
This unit standard is for anyone who has to determine the microbial quality of raw milk by means of the resazurin test.

A person credited with this unit standard is able to:
  • Demonstrate an understanding of the resazurin test as a microbiological intake test.
  • Prepare for the resazurin test on raw milk.
  • Perform the resazurin tests on raw milk.
  • Report on the microbiological quality of raw milk in terms of the results of the resazurin test.

    This unit standard will contribute to the full development of the learner within the dairy manufacturing environment by providing recognition, further mobility and transportability within the field of manufacturing and assembly. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the dairy manufacturing and processing environment.
