Pregnancy and amanitin poisoning

There is a large report on twenty two surviving women from Budapest, Hungary, who had been poisoned by Amanita phalloides and related species. The only abnormality noted was a slightly low birth weight. Five of these women were poisoned in the first trimester of pregnancy, which is the most likely to produce fetal abnormalities. (64) There are also smaller reports of one or two survivals in the second trimester, where toxins generally have less effect on the fetus. (65) There has been one US abortion performed in the first 3 months because of amatoxin poisoning. (66) There is one case of mild toxicity in the nursing child of a mother with amanitin poisoning.
