A woman who was preserving vegetables in a pot and touched a leaf outside the pot on a dry spot, even though the leaf had an egg's bulk of volume, it alone becomes unclean while all the rest remains clean. If she touched it at a wet spot: If there was an egg's bulk in the leaf, everything becomes unclean. If there was not an egg's bulk in it, it alone becomes unclean but all the rest remains clean. If it is returned into the pot, everything becomes unclean. If the woman was unclean due to contact with one who had corpse uncleanness, and she touched the leaf either at a wet spot or at a dry spot: If there was an egg's bulk in the leaf, everything becomes unclean; If there was not an egg's bulk in it, it alone becomes unclean but all the rest remains clean. If a woman who was a tevulat yom emptied out the pot with unwashed hands, and she observed some liquid on her hands, and it is uncertain whether it was splashed from the pot or whether a stalk had touched her hands, the vegetables are invalid but the pot remains clean.

Rabbi Eliezer says: he who eats food with first degree uncleanness contracts first decree uncleanness; [He who eats food with] second [degree uncleanness contracts] second [degree uncleanness]; With third [degree uncleanness contracts] third [degree uncleanness]. Rabbi Joshua says: he who eats food with first [degree] or with second [degree uncleanness contracts] second [degree uncleanness]; With third [degree uncleanness, he contracts] second [degree uncleanness] in regard to holy things but not in regard to terumah. All this applies to common food that was prepared in condition of cleanness that is appropriate for terumah.

First [degree uncleanness] in common food is unclean and conveys uncleanness; Second [degree uncleanness] invalidates but does not convey uncleanness. And third [degree uncleanness] may be eaten in a dish mixed with terumah.

First [degree] and second [degree uncleanness] in terumah are unclean and convey uncleanness; Third [degree uncleanness] causes invalidity but does not convey uncleanness. And fourth [degree uncleanness] may be eaten in a dish containing holy food.

First, second and third [degrees of uncleanness] in holy foods are unclean and convey uncleanness; Fourth [degree of uncleanness] is invalid and causes no uncleanness; And fifth [degree of uncleanness] may be eaten in a dish containing holy food.

Rabbi Eliezer says: the three of them are equivalent.The first degree of uncleanness in holy food, in terumah or in common food: conveys uncleanness at two removes and causes invalidity at one additional remove in the case of holy food; conveys uncleanness at one remove and causes invalidity at one additional remove in the case of terumah; and causes invalidity in common food. The second [degree of uncleanness] in the case of all of them: conveys uncleanness at one remove and causes invalidity at one additional remove in the case of holy food; it conveys uncleanness to common liquids and causes invalidity of terumah food. The third degree of uncleanness in the case of all them: conveys uncleanness to holy liquids and causes invalidity to holy food.

If one eats food with second [degree uncleanness he must not work in an olive-press. Common food that was prepared under conditions proper to the cleanness of consecrated food is still regarded as common food. Rabbi Elazar bar Zadok says: it is regarded as terumah to convey uncleanness at two removes and to render terumah invalid at one additional remove.
