Bagged lettuce takes an interesting journey from field to store. As
soon as it is picked, it is stored in a refrigerated truck to prevent
wilting. The lettuce is separated, washed, and bagged in a factory that
is also refrigerated. Then it is trucked to distribution centers and
eventually to stores.
