Is Amanita Mushroom Poisoning safe while breastfeeding?
Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Amanita Mushroom Poisoning. This is a summary of that source — not our own verdict.
Effects on the breastfed infant
In Germany, a 20-year-old nursing mother ate a meal of solely mushrooms identified in the report as green tuberous mushroom ( Amanita phalloides ). The next morning around 11.5 hours after mushroom ingestion, she nursed her 10-week-old infant who weighed 5 kg. The meal consisted of 80 to 100 mL of breastmilk and the same amount of ready-to-use infant formula (Milasan-Neu). At this time the mother already had symptoms of intoxication (vomiting and diarrhea). Because of the deterioration in her condition, she was unable to continue breastfeeding the child, so the child received only formula thereafter. After the mother was admitted to the hospital for Amanita phalloide s poisoning and had ASAT and ALAT values of 10,000 and 40,000, respectively (normal values about 500-550). The infant was placed under inpatient observation at children s hospital. The infant s relatives noticed nothing unusual about the child and the clinical admission examination revealed no visible evidence of a hepatic, cerebral or hematological disease. Six days after maternal mushroom ingestion, the infant s laboratory values (electrolytes, serum electrophoresis, bilirubin, gamma-GT, alkaline phosphatase, creatinine, blood sugar, urine status, PTT, and PT [Quick test]) were normal except for ASAT and ALAT, which were about double the normal value. These values slowly decreased and became normal at about day 40 after ingestion.[ 4 ] A 32-year-old mother shared a meal of foraged mushrooms ( Amanita bisporigera ), and developed symptoms 15 hours post-ingestion. She presented to the emergency department 29 hours post-ingestion and was found to have markedly elevated liver enzymes. Her 4 month-old-daughter had breastfed 4 hours post-ingestion. The asymptomatic infant was evaluated 48 hours after breastfeeding and discharged from the emergency department with no evidence of hepatotoxicity.[ 2 ] A 33-year-old woman picked about 200 mushrooms in a forest in France. She cooked and ate some of them, and dev

Levels in milk
Maternal Levels. A 32-year-old mother shared a meal of foraged mushrooms ( Amanita bisporigera ), and developed symptoms 15 hours post-ingestion. Amatoxin was undetectable in the milk, although the timing of the milk sample was not stated.[ 2 ] A 33-year-old woman picked about 200 mushrooms in the forest in France. She cooked and ate some of them, then breastfed her 5-month-old daughter 3 times a day over the next 36 hours. The mushrooms were identified as mainly Amanita phalloides along with Paxillus involutus, Amanita rubescens, and Chlorophyllum rhacodes. The mother s urine collected in the emergency department was positive for amatoxin. A breastmilk sample collected 41 hours postingestion had no detectable amatoxin by LC-MS/MS.[ 3 ] Infant Levels.
