Maize meal (posho) served at selected boarding schools in western Uganda is highly contaminated with aflatoxins by Oyesigye, E., Nkurunungi, J.B., Mlahagwa, W., Raymond, A., Mahuku, G., Medina, A.

“…The majority of schools (57.9%) purchase maize flour and beans from any stockist with no contractual obligations (random supplier), and all the 32 schools base on visual parameters, especially white colour, and smell to rule out aflatoxin contamination. Maize flour stored on the ground registered significantly (P = 0.0018) higher levels (54.3 ± 10.1 μg/kg) of total aflatoxins than that stored on a raised platform (14.7 ± 2.6 μg/kg). …”
