The Ministry for Primary Industries has published a document detailing advice on shelf-life of food. It has been developed to help food operators determine the shelf life of their food products and to apply the appropriate date marking.
It provides useful information to help processors and for other food operators preparing and handling foods for retail sale. It clearly highlights appropriate legal requirements, which are either directly quoted from the requirements (including any clause numbers) or are summarised when the requirement is too long to include completely.
