The tri-agency collaborative identified four priority pathogens as the initial focus of their foodborne illness source attribution work:

  • Salmonella,
  • E. coli O157:H7,
  • Listeria monocytogenes, and
  • Campylobacter.

Based on the needs of each agency, CDC, FDA, and FSIS identified both short- and long-term needs related to foodborne illness source attribution, including:

  • Short-term needs that focus on attribution estimates for the four priority pathogens; and
  • Long-term needs that focus on plans for reducing uncertainty, improving data, and obtaining comprehensive estimates of foodborne illness source attribution.
