Chabad.org — Vayikra Chapter 11 with Rashi
Sifra, Shemini, as cited in Niddah 43a.
English: One who touches the carcass becomes impure until evening; touching does not make garments impure, but carrying does, as it says, “and the one who carries it shall wash his garments.”
Halachic distinction — The source distinguishes the impurity of touching from the more stringent impurity of carrying.
Sifra distinguishes the two impurity mechanisms in this section: touching the carcass makes the person impure until evening but does not contaminate the person's clothing, whereas carrying the carcass does contaminate the carrier's clothing.
