Parah 11:3-4

Parah 11:3

Let’s say that pressed figs that were trumah fell into sanctification water, after which they were taken out and eaten. If their volume is the size of an egg, the water is rendered ritually unclean regardless of whether the figs were clean or unclean, and one who eats them deserves death at the hands of Heaven (for eating trumah in a state of impurity). If their volume is smaller than the size of an egg, the water remains ritually clean but one who eats the figs still deserves death. Rabbi Yosi says that if the figs were ritually clean, then the water remains clean. If a person who was clean for the sanctification water puts his head and the greater part of his body into the water, he is rendered unclean.

Parah 11:4

Anyone who must immerse in a mikvah under Biblical law conveys ritual impurity to sanctified food, trumah, unsanctified food and second tithe; such a person is also not permitted to enter the Sanctuary of the Temple. After immersing in a mikvah (but before the sun goes down), such a person conveys impurity to sanctified food and renders trumah unfit; this is the opinion of Rabbi Meir. The Sage, however, say that he renders both sanctified food and trumah unfit. Such a person is permitted to eat unsanctified food and second tithe. If he entered the Temple Sanctuary either before or after immersion, he is liable to the penalty of kareis (spiritual excision).
