Tohorot (tractate)

• Chapter 1: The thirteen regulations concerning the nebelah of a bird, i.e., a fowl not ritually slaughtered; what quantity of such fowl causes uncleanness as nebelah, and what quantity uncleanness merely as other unclean foods; which parts are not included to make up the minimum required quantity; from which moment a head of cattle not ritually slaughtered acquires a lesser degree of uncleanness, i.e., that of ordinary foods, and when the higher degree of impurity, that of the nebelah; which parts are included in order to make up the minimum quantity for the lesser degree, but not for the higher degree (§§ 1-4); the mixing of different unclean foods to make up the required quantity—the size of an egg; cases in which, when the parts possess different degrees of impurity, the entire quantity becomes unclean either in the lesser or in the higher degree (§§ 5-6); parts of a mass of dough or a loaf of bread connected with or touching each other; how the uncleanness of one part affects the others (§§ 7-9).
• Chapter 2: How foods become impure when touched by an unclean person (§ 1); how a person becomes unclean through partaking of impure food (§ 2); difference between foods not sanctified, those constituting "terumah", and other sanctified foods, as regards their becoming unclean in the various degrees (§§ 3-8).
• Chapter 3: Impurity of beverages when in a liquid state, and when they have solidified; which drinks acquire the same degree of uncleanness in the liquid as in the solid state (§§ 1-3); how unclean foods become clean by a change of the prescribed quantity (§ 4); the degree of uncleanness of a thing is judged from the condition in which it is found (§ 5); doubtful cases of uncleanness, when it is not known whether the unclean parts have been touched by the person in question; the difference between reasoning and unreasoning beings in such cases; cases in which it is doubtful whether an animal has transferred impurity from unclean drinks to foods (§§ 6-8).
• Chapter 4: Doubtful cases of impurity (§§ 1-4); six cases in which terumah is burned because of suspected impurity (§§ 5-6); doubtful cases of impurity in which the sages declared the object to be clean; other doubtful cases in which the sages declared the object to be permissible (§§ 7-12).
• Chapter 5: Regulations concerning various cases of doubtful impurity.
• Chapter 6: Difference between private domain ("reshut ha-yaḥid") and public domain ("reshut harabbim") with reference to cases of doubtful impurity: in the former in all doubtful cases objects are to be declared unclean; in the latter, clean (§§ 1-5); different localities which are considered private domain with reference to the Sabbath, but public domain with regard to cases of doubtful impurity (§§ 6-10).
• Chapter 7: Various cases in which a thing is rendered unclean by being touched by a person ignorant of the law ("am ha-aretz"): as such a person does not observe the laws of cleanliness, his touch is necessarily unclean. Cases in which one must suspect an am ha-aretz of having touched foods and drinks, although he, personally, may have had nothing to do with them. If, for example, the wife of an am ha-aretz is seen to attend to the fire in a stove on which a pot containing terumah is standing, it must be assumed that she, although attending to the fire only, has touched the food also; women being generally curious to find out what their neighbors are cooking, she would most likely remove the cover of the pot in order to discover the contents.
• Chapter 8: Further regulations concerning precautions to be taken by one conversant with the Law ("chaber") in order to protect himself against uncleanness caused by the touch of an am ha-aretz (§§ 1-5); what is to be considered fit for human food, thus forming a basis for the regulations concerning the impurity of foods (§ 6); further regulations concerning the impurity of beverages (§§ 7-9).
• Chapters 9-10: Concerning olives and the pressing of oil; how they can be rendered unclean. Other regulations concerning cleanness and uncleanness, with special reference to wine-presses.[1]

The Tosefta to this tractate is divided into eleven chapters, and contains many passages elucidating the Mishnaic tractate.[1]

There is no Gemara for Tohorot in either the Babylonian Talmud or Jerusalem Talmud.
