True or False: Ship sanitation certificates are not required for ships to enter a US Seaport.

The statement that ship sanitation certificates are not required for ships to enter a US Seaport is true. Ships are not mandated to present a ship sanitation certificate upon entering US seaports. This requirement mainly applies to international conventions and guidelines where sanitation inspections are necessary to prevent the introduction of communicable diseases and ensure public health safety.

While certain types of vessels, especially those coming from areas with higher risks for specific health concerns, may still undergo inspections, the blanket requirement for a sanitation certificate doesn't apply. Thus, military and commercial vessels alike can generally enter US ports without this specific documentation, aligning with the correct answer provided.
