This report provides compelling evidence for toxin transmission through breast milk and highlights the diagnostic challenges posed by nonspecific presentations and limited detection methods in pediatric cases. Clinicians evaluating toddlers with unexplained hepatogastrointestinal symptoms, particularly in mushroom-endemic regions, should maintain high suspicion for secondary poisoning and immediately discontinue breastfeeding following maternal toxin exposure. Our findings emphasize the need for evidence-based guidelines for managing breastfeeding mothers with potential mushroom toxin exposure and call for further research on breast milk transmission mechanisms and optimal breastfeeding cessation duration.
