Microbiological Quality and Risk Assessment for Aflatoxins in Groundnuts and Roasted Cashew Nuts Meant for Human Consumption

Table 7

Risk Assessment due to consumption of groundnuts from Obafemi Owode Local Government Area, Ogun State, Nigeria.

Location	Mean aflatoxin; concentration; (ngg^−1)	PDI; (ngkg^−1bwday^−1)	Margin of exposure; (MOE)	Population risk for primary liver; Cancer; (canceryear^−1100,000^−1 population)
“Ajebo”	29.0	25.13	6.76	1.24
“Fidiwo”	33.0	28.60	5.94	1.41
“Obafe”	32.6	28.29	6.01	1.40
“Ogunmakin”	32.8	28.50	5.97	1.41
“Mowe”	33.7	29.28	5.81	1.45
Mean	32.26	27.96	6.10	1.38

Values with different superscripts along the same column are significantly different at . ¹Probable Daily Intake (PDI) calculated by multiplying the aflatoxin concentration in groundnuts by consumption rates of groundnuts in Nigeria (52 g/person/day). ²Margin of exposure (MOE) calculated by dividing the benchmark dose lower limit (BMDL) for aflatoxins by AFB1 exposure. ³Population risk for primary liver cancer = exposure × average potency (0.04944). ⁴Mean of aflatoxin concentration.
