Although in most parts of the world some forms of produce are available year-round, produce is at its best and least expensive when in season. The seasonality of produce depends on regional variables such as climate and weather, and the seasons of the year.
Organic foods are foods produced by organic farming. Currently, the European Union, the United States, Canada, Mexico, Japan and many other countries require producers to obtain special certification in order to market food as organic within their borders. In the context of these regulations, organic food is food produced in a way that complies with organic standards set by national governments and international organizations. Although the produce of kitchen gardens may be organic, selling food with the organic label is regulated by governmental food safety authorities.
