It is extremely important for every country to have national statistics on post-harvest losses and waste of food even when they supply centers (wholesale markets, local markets, supermarkets, retail stores) are not captured.
In the case of Costa Rica statistical data are outdated. In the field of post-harvest losses data are available only for certain crops. After a quick search conducted by the Sustainable Production Department concluded that food waste in market places, no data are available.
