One who carries [an object that has] midras-impurity may [still] carry Terumah but may not carry consecrated foods (Chag. 3:1). How is this done? [If] he had impure sandals, he may carry a jug of Terumah [wine] on his shoulders, but he may not do so with consecrated foods. The clothes of those who eat Terumah are [deemed to possess] midras-impurity vis-a-vis consecrated foods. And the rule of consecrated foods is not like the rule of Terumah. The rule of consecrated foods is greater than the rule of Terumah, since with consecrated foods he [purifies his clothing by first untying any knots and then] immersing and drying [the clothing], and afterwards he reties [any knots], but with Terumah he may [first] tie [the knots] and afterwards immerse them. The same [rule applies to] consecrated foods of the Temple and to consecrated foods of the outlying areas in this regard.
