Eid Al adha sacrifice. It is religious ritual to slaughter a sheep in the name of God. Long time ago people used to make sacrifice people but god made it forbidden so we can slaughter sheep, goats, cows or camels. Then best way will be to distribute meat to poor people, neighbours or relatives, and leave some for yourself. Slaughtering is the best way to kill animal so sheep drains all its blood and it will not transport any infection thru the blood to people.
