The rishon, sheni, and shlishi of sacrificial foods are tamei and contaminate with tumah; the revi’i disqualifies but does not con-taminate with tumah; and the chamishi may be eaten in a dish containing sacrificial food.

The sheni of chullin conveys tumah to chullin liquids and disqualifies terumah foods. The shlishi of terumah conveys tumah to sacrificial liquids and disqualifies sacrificial foods, where [the terumah foods] were made to the taharah standards of sacrificial things. But if they were made to the taharah standards of terumah, it contaminates two and disqualifies one with sacrificial things.

R’ Eliezer says: The three of them are equal. The rishon of sacrificial things, terumah, and chullin conveys tumah to two and dis-qualifies one with regard to sacrificial things; it conveys tumah to one and disqualifies one with regard to terumah; and it dis-qualifies chullin.  The sheni of all of them conveys tumah to one and disqualifies one with sacrificial things; it conveys tu-mah to chullin liquids; and disqualifies terumah foods.  The shlishi with all of them conveys tumah to sacrificial liquids, and disqualifies sacrificial foods.

Someone who eats a sheni food should not work in the oil press. And chullin foods that were made to the standard of sacrificial foods —- these are like chullin. R’ Eliezer bar R’ Tzadok says: They are like terumah, to convey tumah to two and disqualify one.
