DFWED Food Vehicle Investigation Module

Section 1: Use Case Identifiers

Use Case ID: HHS-CDC-00041
Agency: HHS
Op Div/Staff Div: CDC
Use Case Topic Area: Mission-Enabling (internal agency support)
Is the AI use case found in the below list of general commercial AI products and services?
None of the above.
What is the intended purpose and expected benefits of the AI?
Foodborne outbreak investigation

Outbreak investigation by providing estimates of output of potential food vehicles can increase speed of tracking foodborne outbreaks in terms of identification of hypothesis generation. This reduces operational burdens in foodborne response efforts.
Describe the AI system's outputs.
NLP and Food Vehicle Investigation Module (FVIM) uses language learning models and Text Classification Tools to identify potential vehicles. NLP tool uses text classification to provide probabilities that a food is associated with the outbreak based on reports in the SEDRIC line list. FVIM identifies past outbreak with similar key demographic and temporal characteristics to the selected outbreak to guide hypothesis generation. FVIM analyses reported food exposures uploaded to the SEDRIC line list and categorizes responses into food commodity types that are then compared to FoodNet Population survey results weighted by age, sex and ethnicity and generates a statistical comparison
Stage of Development: Operation and Maintenance
Is the AI use case rights-impacting, safety-impacting, both, or neither?
Neither
