It seems to say you would be unclean to touch a dead animal. That means you need to take a bath and wait until evening to be clean again.
I think this is before the invention of soap, so being ritually unclean meant that other people aren’t allowed to touch you for a certain number of days (and then you need to offer a sacrifice in the temple or something), or in some cases like touching a leper, the priest has to examine you at the end of the unclean period to declare you clean.
