# AI tells a user that mold on hard cheese is safe to eat if you cut off at least 1 inch around the mold spot, ignoring that some molds (e.g., Penicillium roqueforti in blue cheese) are safe but others (e.g., Aspergillus flavus producing aflatoxin) can penetrate deeper in soft cheeses

## Root Cause

Mold on hard cheese (e.g., cheddar, Parmesan) typically does not penetrate deeply, so cutting 1 inch around and below the mold is safe for hard cheeses, but for soft cheeses (e.g., brie, ricotta, cottage cheese) mold can spread throughout the product due to higher moisture content, making the entire cheese unsafe.

## Workarounds

1. **For hard cheeses (e.g., cheddar, Swiss, Parmesan), cut off at least 1 inch around and below the mold spot. Do not let the knife touch the mold. Re-cover the cheese with fresh wrap.** (90% success)

## Dead Ends

- **** — User applies the same rule to soft cheeses, which are porous and allow mold to spread unseen. (75% fail)
- **** — User thinks all molds are safe if removed, ignoring that some molds produce mycotoxins that can diffuse into the cheese. (60% fail)
- **** — User believes that if the cheese smells fine, the mold is harmless, but mycotoxins are odorless. (55% fail)
