14)[line 30]ליטמא לח ויבשLITAMEI LACH V'YAVESH! - it should cause Tum'ah not only when it is moist (i.e. when it contains its bodily fluids) but even when it is dry (i.e. when it has dried out)! (TUM'AS SHERETZ)
(a)A Sheretz (a crawling pest - see Background to Shabbos 107:5), even if it or a part of it is only the size of an Adashah (lentil bean), is an Av ha'Tum'ah (Vayikra 11:29-38, Chagigah 11a). It makes a person or object Tamei through Maga (contact), whether the Sheretz was touched willingly or unwillingly. The person who becomes Tamei by touching a Sheretz may not eat Terumah or Kodshim or enter the Azarah of the Beis Ha'Mikdash. However, he can immediately immerse in a Mikvah. After nightfall he becomes Tahor and may eat Terumah or Kodshim or enter the Azarah.
(b)The Mishnah in Nidah (54b) states that a Sheretz is Metamei only when it still contains its bodily fluids. Once it has dried out, it can no longer be Metamei.
