Aflatoxin B₁levels in groundnut and sunflower oils in different Sudanese states

Abstract

In this article, the level of contamination of aflatoxin B1 (AFB1) in groundnut and sunflower oils was determined. The 241 oil samples were collected from Khartoum, Gezira, Kordofan and Algadarif states of Sudan and assessed for AFB1 using high-performance liquid chromatography (HPLC). AFB1 levels in groundnut oil samples ranged from 0.5 to 70 µg/kg and were 0.7 to 35 µg/kg in sunflower oil samples. High contamination was found in unrefined samples. It was concluded that AFB1 levels in oil samples indicated that growing, harvesting, handling and storage of the crops were not done properly.

Extent of Microbial Contamination of Refined and Unrefined Vegetable oils sold in South-west Nigeria

“…This work has been able to establish that unrefined oil has more fungal load than the refined oils which are in accordance with the findings of Elzupit et al (2010) and Mariod and Idris (2015) and that consumers should limit the rate at which they consume unrefined oils because they are more susceptible to aflatoxins contamination. Hence, protective measures must be followed during the refinning processes.…”

Worldwide Mycotoxins Exposure in Pig and Poultry Feed Formulations

“…The presence of aflatoxin B1 in sunflower oils and mustard suggests that this mycotoxin could be present in sunflower and grapeseed meals [132,133]. In the same way, because zearalenone was found in rapeseed and maize oils it could also be present in the meals, but probably at a lower concentration than that observed in maize [131].…”

Nutrient Composition and Aflatoxin Contamination of African Sourced Peanuts and Cashew Nuts: Its Implications on Health

“…Analyses of peanut oil samples have shown the presence of aflatoxins especially in the unrefined oils. It has also been reported that oils extracted from peanuts often have higher aflatoxin contamination [113]. Abalaka [114], highlighted the use of crude oils by the majority of the Nigerian population hence their exposure to aflatoxins [114].…”
