Evaluating the potential health risk of organochlorine pesticides in selected protein foods from Abeokuta southwestern Nigeria

Abstract

This study evaluated the potential health risk of OCPs in selected protein foods. A total of 66 food samples were collected from selected areas in Abeokuta, southwestern Nigeria. Food samples were analyzed for OCPs using the standard method. OCP data were analysed for descriptive and inferential statistics. Health risk assessment was conducted for non-carcinogenic {Hazard Quotient (HQ), Hazard Index (HI) and Cancer Risk (CR)}. The ΣOCP concentration was observed highest in pork (42.20 ± 33.33 mg kg −1) of which methoxychlor and dieldrin represented 63 and 28%, respectively. The HIs of OCPs in protein foods were generally greater than 1.0 indicating adverse effects. The ΣCR data showed carcinogenic effects in protein foods with values greater than the acceptable limit of 1.0 × 10 −4 .

Screening of pesticide distributions in foods of animal origin: a matrix-based approach for biotransfer factor modeling of grazing mammals

“…More importantly, particularly for lipophilic pesticides, indirect consumption via eating animal parts aer they have eaten fodder contaminated crops over months or even years is an important pathway. 16,17 Also, even under low exposure doses (e.g., low residue levels in feed materials), lipophilic and persistent pesticides (e.g., lindane) can have a high degree of bioaccumulation in the livestock with a long life cycle (e.g., cattle and sheep), as compared to some shortlife-cycle grazing animals such as chicken and duck. 18 Therefore, understanding the quantitative relationships associations of pesticide concentrations in different edible parts of livestock from animal feed is essential for health risk and impact assessments, and MRL determination for foods of animal origin, which can also be a complementary component to "direct human consumption of crops" as current basis of evaluating and management pesticide residues in crops.…”
