| dc.description.abstract | The thrust of this study was to estimate the risk of dietary consumption of acrylamide. Such a study is essential in order to monitor exposure levels and protect the safety of consumers. Stratified sampling was used to sample 89 food matrices from vendors in selected towns. Six hundred and twenty nine (629) consumers were interviewed using a semi-structured questionnaire in a one week dietary recall survey. Acrylamide quantitated using Thermo Scientific Mircro-Volume UV-Vis NanoDrop spectrophotometer. The analytical approach adopted in this work used the probabilistic method to account for the randomness of the data acquired. The findings from this study show a 50 % percentile acrylamide concentration in the foods analyzed as 1.56 mg/g, a 50 % percentile acrylamide exposure of 0.100 mg/kg-day, a modal cancer risk of 9x10-5 and modal neurotoxic risk -0.0008. The main conclusions drawn from this study are that there is no neurotoxic risk due to dietary acrylamide in the study area but there is a probable cancer risk of 9 out of 100,000 due to dietary acrylamide, which is unacceptable compared to the 1x10-6 de minimis value. As such, this study recommends further investigation with a view to providing intervention towards the reduction of acrylamide levels to levels below 0.001mg/g in heat – processed commonly eaten foods. | en_US |
