## Root Cause

Peanut butter, even if xylitol-free, can contain aflatoxins from moldy peanuts, which are potent hepatocarcinogens and can cause acute liver failure in dogs.

## Dead Ends

- **** — Aflatoxin contamination is sporadic and brand-independent; any brand can have a bad batch (70% fail)
- **** — Almond butter can also contain aflatoxins and may have higher fat content, risking pancreatitis (60% fail)
- **** — Aflatoxins are heat-stable and not destroyed by boiling; they remain toxic even after cooking (90% fail)
