Breast milk from 113 mothers in two 'Under-Five Clinics' in the Southern Province of Sierra Leone, namely, Njala and Bo, were examined for their mycotoxin content. Only 10 were mycotoxin-free. Eighty-eight per cent of samples contained various aflatoxins and 35% contained ochratoxin A (OTA). Few samples (15%) had a single mycotoxin. Thirty-six (32%) had two mycotoxins and 50 (40%) had three or more. The occurrence of OTA in combination with various aflatoxins was recorded. It is concluded that infants in Sierra Leone are exposed to OTA and aflatoxins at levels which in some cases far exceed those permissible in animal feed in developed countries.

Analysis of 64 cord blood samples from pregnant women in Sierra Leone revealed the presence of ochratoxin A (OTA) and aflatoxins in 25% and 58% of samples, respectively. Of the eight maternal blood samples collected during delivery, one contained OTA and aflatoxins were detected in six. There was no relationship between mycotoxins in maternal and cord blood. The effect these toxins might have had on the birthweight of infants is discussed.
