Are you using the correct estimate?

Let’s use Salmonella illnesses as an example. Refer to Table 2.

  • If you are looking for the total number of illnesses, use the number from the column labeled “Total.” An estimated 1.2 million Salmonella illnesses occur each year in the United States.
  • If you are looking for the number of illnesses not related to international travel, use the number from the column labeled “Domestically acquired.” Of the estimated 1.2 million Salmonella illnesses, an estimated 89 percent are acquired in the United States (and 11 percent are acquired during international travel).
  • If you are looking for the number of foodborne cases, use the number from the column labeled “Domestically acquired foodborne.” An estimated 94 percent (about 1 million) of the Salmonella illnesses acquired in the United States are foodborne.
