A Guide to Calculating the Shelf Life of Foods

Information Booklet for the Food Industry

February 2005

The New Zealand Food Safety Authority (NZFSA) and Health Protection Officers regularly deal with enquiries on the shelf life and date marks on foods. This Guide to Calculating the Shelf Life of Foods contains background information on the factors that influence shelf life and a procedure to assist you to calculate the shelf life of foods.

Although the shelf life and date mark requirements are detailed in legislation, the guide provides assistance to meet these requirements and should be read in conjunction with the Australia New Zealand Food Standards Code.
