Abstract
A method for washing a cored head of lettuce includes placing the head in a position such that the cored hole faces downwardly, spraying an aqueous solution upwardly into the cored hole for a time and at a pressure sufficient to wash the hole, and then propelling the cored washed lettuce head upwardly from the washing position onto a conveyor for the lettuce head with minimal damage to that head.
