# 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 E. coli, Salmonella, and Listeria

## Root Cause

Raw milk can contain harmful bacteria from the cow's udder, manure, or environment even on clean farms; pasteurization is the only reliable method to kill pathogens without affecting nutritional value.

## Workarounds

1. **Use pasteurized milk from a trusted dairy; check for 'Pasteurized' label on the carton. Example: `grep -i pasteurized milk_carton.txt && echo 'Safe to drink'`** (95% success)

2. **If raw milk is the only option, heat it to 161°F (72°C) for 15 seconds (high-temperature short-time pasteurization) using a food-grade thermometer. Example: `heat --temperature 161 --time 15s raw_milk.txt`** (80% success)

3. **For cheese made from raw milk, ensure it is aged at least 60 days at 35°F (2°C) to reduce pathogen risk; check FDA guidelines for aged raw milk cheese** (70% success)

## Dead Ends

- **** — Boiling kills pathogens but changes the taste and nutritional profile; also, many people do not boil it long enough or at a high enough temperature to ensure safety (92% fail)
- **** — Even clean farms can have sporadic contamination from wildlife, feed, or equipment; no farm can guarantee zero pathogens without pasteurization (99% fail)
- **** — Home UV or ozone treatments are not standardized and may not penetrate milk adequately to kill all pathogens; they are not FDA-approved for milk safety (95% fail)
