February 24, 2015, 8:30 a.m. – 5:00 p.m. EST: Public Meeting, Washington, D.C.

IFSAC presenters provided updates on completed and ongoing projects focusing, on a key project where IFSAC developed, for the first time, a single approach to produce harmonized foodborne illness source attribution estimates from outbreak data for Salmonella, Escherichia coli (E. coli) O157, Listeria monocytogenes, and Campylobacter. IFSAC provided an overview of the project approach, analytical methods, results, and the utility of estimated attribution.

Objectives of the Public Meeting:

  • Share IFSAC’s progress toward our goals.
  • Engage with the public and our food safety partners on IFSAC work to improve foodborne illness source attribution.
  • Solicit feedback on plans for future IFSAC endeavors.
