The responsibilities of the USDA's Plant Protection and Quarantine service include assigning risk rankings to countries-of-origin of imported commodities of agricultural interest. Scientists at the Center for Plant Health Science and Technology, researchers from North Dakota State University and PPQ staff developed methods to discover which countries' air passenger flights can consistently be ranked low or high risk and to find those countries that have a mixture of low to high ranking flights. The tool provides improved risk ratings for the air passenger/baggage pathway and methods to address that risk. The tool assigns risk to each flight based on the flight’s passenger count, the record of quarantine commodities historically found on the flight, and the relative risk associated with each commodity and, in doing so, breaks new risk management ground for the service.
