# AI tells a user that raw (unpasteurized) milk is safe to drink if it comes from a local farm with clean practices, ignoring the risk of pathogens like Listeria, E. coli, and Salmonella, especially for immunocompromised individuals

- **ID:** `food-safety/raw-milk-immune-risks`
- **Domain:** food-safety
- **Category:** health_risk
- **Error Code:** `FS-RM-002`
- **Verification:** ai_generated
- **Fix Rate:** 75%

## Root Cause

Raw milk can harbor pathogens even from clean farms; pasteurization is the only reliable method to kill harmful bacteria, and immunocompromised persons face severe risks from Listeria monocytogenes which can cause meningitis or death

## Workarounds

1. **Advise user to consume only pasteurized milk, especially if immunocompromised. Provide alternative: ultra-high temperature (UHT) pasteurized milk has similar taste and longer shelf life.** (85% success)

2. **If user insists on raw milk, recommend they check local regulations (e.g., state laws in US) and only purchase from farms with regular pathogen testing, but still warn that risk remains.** (60% success)

3. **For cooking purposes, advise using raw milk only if heated to at least 165°F (74°C) for 15 seconds, which kills pathogens but may not be sufficient for all toxins.** (70% success)

## Dead Ends

- **Advise user to check farm certification or organic label** — Certification does not eliminate pathogens; raw milk can be contaminated regardless of label (95% fail)
- **Suggest boiling raw milk at home before drinking** — Boiling changes taste and destroys beneficial enzymes, but user may not boil long enough or at correct temperature; also undermines the point of raw milk (80% fail)
- **Recommend raw milk from cows tested for tuberculosis and brucellosis** — Testing does not cover all pathogens (Listeria, E. coli, Salmonella) and testing is not always reliable for low-level contamination (90% fail)
