Abstract

Aflatoxin contamination of maize is a serious food safety problem worldwide.
Despite the widespread consumption of maize in Nigeria, there is limited data
on aflatoxin contents of maize vended in open markets in Ondo state, Nigeria.
A total of 140 maize samples randomly purchased from major markets in four
locations in Ondo state, were screened for total aflatoxins using an ELISA
method. Exposure and health risk assessments were performed for the maize
consumers by the deterministic and Margin of exposure (MOE) approaches,
respectively. About 99% of the maize were contaminated with total aflatoxins
(range: 0.65–265 ?g/kg; mean: 125.9 ?g/kg). Aflatoxin levels exceeding the 4
?g/kg set by the European Union for total aflatoxins were found in 88% of the
maize whilst more than one half contained at least 100 ?g/kg aflatoxins. The
average probable daily intake values were 830, 332 and 138 ng/kg bw/day for
the average children, adolescent and adult populations, respectively.
Consequently, MOEs for the respective populations were 0.20, 0.51 and 1.23,
suggesting a high level of health risk for consumers of maize vended in open
markets in Ondo state due to high aflatoxin levels. Maize farmers and
households in Ondo state need urgent aflatoxin mitigation interventions.
