Leviticus 11:35

31 These animals are unclean for you among all the crawling creatures. Whoever touches them when they are dead shall be unclean until evening.

32 When one of them dies and falls on something, that article becomes unclean; any article of wood, clothing, leather, sackcloth, or any implement used for work must be rinsed with water and will remain unclean until evening; then it will be clean.

33 If any of them falls into a clay pot, everything in it will be unclean; you must break the pot.

34 Any food coming into contact with water from that pot will be unclean, and any drink in such a container will be unclean.

35 Anything upon which one of their carcasses falls will be unclean. If it is an oven or cooking pot, it must be smashed; it is unclean and will remain unclean for you.

36 Nevertheless, a spring or cistern containing water will remain clean, but one who touches a carcass in it will be unclean.

37 If a carcass falls on any seed for sowing, the seed is clean;

38 but if water has been put on the seed and a carcass falls on it, it is unclean for you.

39 If an animal that you may eat dies, anyone who touches the carcass will be unclean until evening.
