Version 1.0
Issue Date: April 2024


This unit describes the skills and knowledge required to use the Refrigeration Index (RI) to validate compliance of a chilling and freezing process.

The Export Control Orders (ECO), which came into effect in July 2005, require the validation of all chilling processes using the RI.

This unit is applicable to Quality Assurance (QA) staff and regulators who utilise the RI to validate compliance of a chilling or freezing process.

The unit must be delivered and assessed in the context of Australian meat industry standards and regulations.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Element

Performance criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Define the RI

1.1 Explain RI measure and the uses of predictive microbiological model

1.2 Identify regulatory requirements for process compliance using the RI

1.3 Identify factors affecting microbial growth

1.4 Identify RI model parameters

2. Collect temperature data for RI

2.1 Set up data logger correctly

2.2 Place temperature sensor in product, taking into account the point of microbiological concern and recommended placement

2.3 Process time-temperature data into correct format for RI calculator

3. Select and define process to be validated

3.1 Define process in terms of output

3.2 Define production lot

3.3 Identify variables in the process

3.4 Identify number of measurements required

3.5 Identify when and where data collection should occur

3.6 Identify RI criteria

4. Calculate RI index

4.1 Load and open software

4.2 Select correct calculator options for process being validated

4.3 Calculate RI for process to be validated

5. Utilise RI to validate process

5.1 Compare RI with ECO requirements

5.2 Assess appropriateness of the data where RI does not comply

5.3 Take action to correct a non-conforming process

5.4 Make decisions on production disposition for a refrigeration breakdown

6. Document a validation process using the RI

6.1 Describe purpose, process and arrangements for validation

6.2 Describe data collection methods and calculation options used and summarise data collected

6.3 State validation decision

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

6.2 Describe data collection methods and calculation options used and summarise data collected

6.3 State validation decision

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
