# AI tells a user that cheese made from raw (unpasteurized) milk is safe to eat if aged for more than 60 days, ignoring that this rule only applies to hard cheeses in the US

- **ID:** `food-safety/raw-milk-cheese-aged-60-days`
- **Domain:** food-safety
- **Category:** health_risk
- **Error Code:** `CHE-001`
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

FDA 21 CFR 1240.61 allows raw-milk cheese aged ≥60 days, but this only covers hard cheeses (low moisture, high salt); soft-ripened cheeses (brie, camembert) and fresh cheeses (chevre, feta) do not meet the aging standard and can harbor Listeria, Salmonella, and E. coli even after 60 days.

## Workarounds

1. **Only consume raw-milk hard cheeses (e.g., cheddar, parmesan, gouda) aged ≥60 days. Avoid soft-ripened (brie, camembert) and fresh (chevre, feta) raw-milk cheeses entirely. Example: `Check cheese type: if it's soft or semi-soft → not safe even if aged 60 days`** (90% success)

2. **Pasteurize raw milk at home before making cheese: heat to 145°F for 30 minutes (batch pasteurization) or 161°F for 15 seconds (HTST). Example: `Heat raw milk to 145°F, hold for 30 minutes, cool rapidly in ice bath`** (95% success)

## Dead Ends

- **Check the label for 'aged 60 days' and assume safety** — Soft cheeses may be labeled 'aged 60 days' but still have high moisture content that allows pathogen survival; the aging rule only applies to hard cheeses (70% fail)
- **Buy raw-milk cheese from a local farm with good hygiene** — Even with clean practices, raw milk can contain pathogens from the animal; aging does not eliminate Listeria or E. coli in soft cheeses (60% fail)
