Keith on DelMarVa - 3/4/2011 13:23 bagged potatoes are washed. potatoes going into storage arent washed until they are taken out of storage. I get mine straight from the bulk bodies before they go into the flume or straight from the field when digging to get a size profile for the grower. these always last much much longer than the ones I get from the pack line. plus what was mentioned above about cold/humid storage
