Secure Egg Supply (SES) Project

Funded 2007-Present

This project is funded by USDA APHIS National Preparedness and Incident Coordination Center (NPIC).


  • To minimize the risk of exposure of poultry flocks to HPAI and to thereby limit the spread of HPAI during an outbreak
  • To provide a high level of confidence that eggs and egg products entering market channels for human consumption are free of HPAI virus
Secure Egg Supply.


We've prepared two videos describing the voluntary preparedness component of the Secure Egg Supply Plan.

  • Pre-event biosecurity assessment developed with support of industry, state, federal, academic partners
  • Oropharyngeal swabbing DVD and training materials (English and Spanish) developed and distributed to ensure proper sample collection and submission
  • Epidemiologic questionnaire to determine exposure risks developed with support of CEAH, industry, state, federal and academic partners
  • Secure Egg Supply Data Portal for producers to share production data, mortality information, laboratory results as a rapid decision tool for Incident Command in the event of an HPAI outbreak
  • Enrollment of approximately 55 million laying hens (out of a total of 57 million in Iowa) in the preparedness component of the Secure Eggs Supply Plan; other states are invited to participate
  • Collaboration with Texas A&M FAZD Center to incorporate Iowa data into the ERSS Dashboard
