What does Leviticus 7:18 mean?

If anyone eats the meat from the peace offering on the third day, the offering won't count for anything. God won't accept it, and the person who eats it will be guilty and responsible for what happens. Leviticus 7:18 - Modern Text Bible

(Eating the meat after the allowed time makes the offering invalid, and the person who does it is held responsible for breaking the rule.)
