Rashi on Leviticus 6:20/רש"י על ויקרא ו׳:כ׳

1כל אשר יגע בבשרה WHATSOEVER SHALL TOUCH THE FLESH THEREOF [SHALL BECOME HOLY] — any article of food that shall touch it and absorb anything of it (cf. Sifra, Tzav, Section 4 5; Zevachim 97a and Rashi on v. 11),

2יקדש SHALL BE HOLY, so as to become exactly like itself: if it (the sin-offering) has become invalid, it (the food touching it) also becomes disqualified, and if that be fit for eating this may be eaten only under the same stringency applying to it (the sin-offering).

3ואשר יזה מדמה על הבגד means, and if there is splashed of the blood thereof on a garment, that blood-stained spot in the garment whereon it was splashed shalt thou wash in the forecourt (Sifra, Tzav, Chapter 6 3).

4אשר יזה means, shall be splashed. It is the same as the verb in (Job. 15:29) “and their substance shall not be spread (יטה) on earth” (cf. Rashi on that verse).
