Abstract:Of 15 live births in one Hungarian village in 1989-90, 11 (73%) were affected by congenital abnormalities and 6 were twins. Of the 11, 4 had Down syndrome. Likely causes of such clusters (known teratogenic factors, familial inheritance, consanguinity) were excluded. A case-control study and environmental investigations pointed the finger of suspicion at the excessive use of trichlorfon at local fish farms. The content of this chemical was very high in fish (100 mg/kg) and several pregnant women, including all mothers of babies with Down syndrome, had consumed contaminated fish in the critical period for the congenital abnormalities observed.
