One who eats an ant or a louse that is in produce is liable. [One who eats] a mite that is in lentils, or a gnat that is in k'lisin (a carob-like fruit), or a worm that is in dates or figs, is exempt. [The Sages then] reconsidered and changed their mind [and rendered him] liable. [One who eats] a worm in tree roots, or a [different species of] worm in vegetables is liable. [If he consumed] a red gnat within wine or vinegar, behold, this is permitted (מותרין not אסורין per Lieberman and GR"A). [On the subject of wine and vinegar,] Rabbi Yehudah says, those who filter wine or vinegar, and those who make a blessing over the sun (birkat hachama, a blessing made every 28 years), behold, these are foreign (i.e., heretical) practices.
