Food Safety Outbreak Investigation Assistant
Analyze foodborne illness outbreaks to identify sources and control measures
by skillslibEnvironmental & SustainabilityEnvironmental ScienceEnvironmental Health SpecialistFood SafetyWhat You Can Do
You can organize complex outbreak case data, identify common exposures across multiple affected individuals, analyze incubation periods to narrow suspect foods, and generate contamination hypotheses. Claude helps you cross-reference food sources with illness timelines, stratify risk levels for follow-up investigations, and develop prioritized intervention strategies that guide environmental health enforcement actions.
Features
structure case information (symptoms, onset times, exposures, demographics) into analyzable format for pattern detection
identify common foods and venues across geographically dispersed cases to narrow suspect sources
use symptom onset timing to estimate likely contamination windows and suspect food categories
develop evidence-based theories about where and how foodborne pathogens entered the supply chain
rank food establishments and sources by likelihood of contamination to guide environmental sampling and enforcement priorities
organize supplier and distribution data to identify contamination points across supply chain
generate control measures targeting identified critical control points and hazards
Example Output
Example 1: Restaurant Outbreak Analysis
Input: 8 cases with gastroenteritis, onset 6–18 hours post-exposure, all attended same restaurant event
Output:
- Common exposure: Oyster appetizer (6/8 cases)
- Incubation window: 6–18 hours suggests bacterial toxin (Staphylococcus aureus)
- Contamination hypothesis: Oysters prepared in warm holding for 4+ hours without temperature control
- Risk ranking: (1) Oyster supplier inspection urgent, (2) Food handler temperature control audit, (3) Equipment temperature logging review
- Recommended controls: Cold chain verification, handler hygiene retraining, time/temperature monitoring system
Example 2: Multistate Cluster Traceback
Input: 23 cases across 4 states, linked to Salmonella in ground beef products
Output:
- Geographic pattern: Cases cluster in regions with one beef distributor
- Timeline: Cases occur 2–4 days post-product purchase
- Contamination source hypothesis: Grinding facility cross-contamination or raw material supplier
- Supply chain vulnerabilities: 3 processing plants identified as common suppliers
- Recommended interventions: (1) Distributor quarantine, (2) Environmental sampling of grinding facility, (3) Supplier audit, (4) Product recall guidance
What's Included
- SKILL.md: structured outbreak investigation methodology and decision framework
- Case Data Template: standardized form for collecting symptoms, timelines, exposures, and demographics from affected individuals
- Epidemiological Analysis Worksheet: incubation period calculator, exposure cross-reference matrix, and common source identification checklist
- Risk Stratification Scoring Tool: objective criteria for ranking establishments and sources by contamination likelihood
- Investigation Report Framework: sections for findings summary, hypothesis, contamination source analysis, and control recommendations aligned with regulatory reporting standards

Best For
- Foodborne illness outbreak investigations with confirmed or suspected common exposure
- Cluster analysis across geographically dispersed cases with multiple potential sources
- Incubation period analysis to narrow suspect foods and contamination windows
