Guidelines For Food Safety
Validation and Verification of Heat Treatment Equipment and Processes

1

FOREWORD
The development of this Guideline is an initiative of the Australia New Zealand Dairy Authorities’ Committee (ANZDAC). Members of ANZDAC are: Australian Quarantine andInspection Service Dairy Authority of South Australia Dairy Food Safety Victoria Department of Health Western Australia New South Wales Food Authority New Zealand Food Safety Authority Safe Food Queensland Tasmanian Dairy Industry Authority This Guideline is not intended as a mandatory standard. The purpose of this Guideline is to assist industry and regulators with the implementation of foodsafety standards and the application of good food safety practice. Accordingly, this Guideline may require amendment from time to time in order to remain aligned with food safety standards.

Guidelines for Food Safety: Validation and Verification of Heat Treatment Equipment and Processes

Introduction
With the emphasis on food safety within the dairy industry and the regulated implementation of HACCP based food safety programs there exists a need to ensure that heat treatment equipment such as pasteurisers are designed, installed, operated and verified in a manner thatresults in no untreated or partially treated milk or dairy products. This document prepared by a working group under the direction of the Australia and New Zealand Dairy Authorities Committee (ANZDAC) was developed to provide guidance on equipment and processing parameters that are to be reviewed and assessed as part of validation and verification of heat treatment. Systems for the validation andverification of heat treatment should be incorporated as an integral part of each dairy factory’s food safety program, where critical heat treatment processes are conducted. For each heat treatment process and/or pasteuriser the dairy factory will be expected to have a program of checking and testing including procedures and recording of the results of such activities. The requirements for thepasteurisation and heat treatment of milk and dairy products are contained in the Food Standards Code, the Export Control (Milk and Milk Products) Orders 2005 and the relevant State, Territory or Country legislation.
