The potato program combines a potato regulatory program, including plant disease and pest control; quality characteristics, grower education and the enhancement of potato marketability.
To be eligible for marketing, seed potatoes must undergo an inspection and certification program to restrict the spread of diseases to other farms and areas. Planting certified seed potatoes is required in most of the U.S. and in any importing country. Planting certified seed potatoes in Minnesota meets minimum disease standards and prevents the spread of plant diseases and pests.
In order to help determine if any late season spread of certain virus diseases has occurred, all seed potato fields are sampled at harvest for additional testing during the winter.
There are no requirements for inspections for fresh and processing potatoes in Minnesota, but growers and shippers are better protected when an inspection certificate is available. Payment to growers is often based on inspection reports in both the processing and fresh potato industry.
Shipping Point Inspection enables the industry to ship seed potatoes as "certified" and provides grades for fresh, processing and seed potatoes.
The shipping point inspection program provides voluntary and mandatory shipping point inspection to the industry, which certifies the shipments as within grade. Shipping Point Inspection is the last control measure to prevent diseased potatoes from being shipped and the first look from government at our food supply.
