[Regarding] one whom a t’mei meis touched, who had foods and beverages in his mouth, [if] he inserted his head into a tahor oven, they render it tamei. And a tahor person who had foods or beverages in his mouth, and he inserted his head into the airspace of a tamei [earthenware] oven, they are rendered tamei. [If one] was eating a pressed fig with soiled hands, [and] he inserted his hand into his mouth to remove a pebble, R’ Meir rules [it] tamei, but R’ Yehudah rules [it] tahor. R’ Yose says: If he turned [it] over, it is tamei. [But] if he did not turn [it] over, it is tahor. [If] there was a pundyon in his mouth, R’ Yose says: If [it was] to [relieve] his thirst, it is tamei.

[Regarding] a woman from whose breasts milk dripped and [the milk] fell into the airspace of an oven, [it is] tamei, for a beverage can transmit tumah whether one was pleased or was not pleased. If she was shovel- ing ashes out of [the oven], and a thorn hit her and she bled, or she was burned, and put her finger into her mouth, [the oven] becomes tamei.
