Description
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.
Notes
