clean bill

Quick Reference

The description of a ship when all the ship's company are in good health. A ship's bill of health is a certificate signed by a consul or other port authority that no contagious disease existed in the ship's port of departure and that none of the crew was infected with a notifiable disease at the time of sailing. Such a bill of health, properly authenticated, is a clean bill; where it cannot be so authenticated because of infection in the port of departure, it is a foul bill.
