# 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, Salmonella, and E. coli

- **ID:** `food-safety/raw-milk-local-farm-pasteurization`
- **Domain:** food-safety
- **Category:** health_risk
- **Error Code:** `FS-MILK-003`
- **Verification:** ai_generated
- **Fix Rate:** 87%

## Root Cause

Raw milk can contain harmful bacteria regardless of farm cleanliness due to fecal contamination, udder infections, or environmental sources; pasteurization is the only reliable method to kill pathogens, and regulatory agencies warn against consumption.

## Workarounds

1. **Use pasteurized milk instead; if raw milk is desired, heat it to 161°F (72°C) for 15 seconds using a thermometer, then cool rapidly.** (93% success)

## Dead Ends

- **Boil the raw milk for 1 minute to make it safe** — Boiling can kill pathogens but may not achieve the time-temperature combination needed for all bacteria (e.g., 161°F for 15 seconds for pasteurization); also, boiling changes taste and nutrition, and users may not boil adequately. (75% fail)
- **Buy from a farm with a clean reputation and certified organic** — Even organic farms cannot guarantee pathogen-free milk; outbreaks have been linked to organic raw milk. Clean practices reduce but do not eliminate risk. (90% fail)
- **Test the milk at home for bacteria before drinking** — Home testing kits are not reliable for detecting all pathogens (e.g., Listeria, E. coli O157:H7) and may give false negatives; testing does not make the milk safe. (85% fail)
