Abstract
Studies on 125 primigravidae in rural Kenya revealed aflatoxins in the blood of 54 prenatally. At delivery re-examination of 34 showed aflatoxins in 12 previously negative. The overall detection rate was 53%. Blood from additional 59 women collected at delivery showed aflatoxins in 53%. Aflatoxins were detected in 37% of 101 cord bloods. There was no relationship between aflatoxins in maternal and cord bloods. The frequency of detection was significantly higher in maternal and cord bloods during the 'wet' than 'dry' months. The mean birth weights of females born to aflatoxin positive mothers was significantly lower (255 g) than those born to aflatoxin free mothers. Two stillbirths were recorded, in both cases maternal and cord blood showed aflatoxins. These findings and the adverse effects of prenatal aflatoxin exposure recorded in animal experiments indicate the need for further study of the effects of aflatoxins on the human foetus and newborn.
