Postharvest is a complex topic encompassing orchard practices, harvest methods, quality evaluations, storage regimes, sanitation practices, food safety, pathology, handling and packing practices, transportation, and even marketing and export concerns. WSU researchers have been active in all of these areas and are at the forefront of developing new technologies used in various aspects of postharvest. WSU researchers also work closely with researchers from both other universities, such as Oregon State University, and USDA-ARS to maximize efforts for the PNW tree fruit industry.

Postharvest Information Network
The old Postharvest Information Network website has been retired along with the aging server that hosted the site. We realize that this is an inconvenience to many of you who relied on that source for the articles, reports, and news articles provided by Dr. Kupferman. Much of that old content is still available but will need to be requested until we have developed a new archive on the Postharvest Systems website. To request articles please contact Chris Hedges, Postharvest ITT.
