“…In addition, other agroecological zones had 10% peanut samples with AF contamination in levels above 10 μg/kg with exception of North Eastern which had none of the samples with detectable AFs. The report is substantiated by investigations of Baluka et al [72] which reported that 34% of 55 peanut samples analyzed in a study contained AFs in concentrations greater than the East African and FDA/WHO compliance limits for AFs in peanuts.…”

“…Thus, most studies reported AFB1 levels or did not distinguish between the different types [64][65][66][67][68][69]. Others, such as the validation survey of Wacoo et al [70], Muzoora et al [71], Baluka et al [72] and Wacoo et al [73] differentiated the AFs. By and large, the lack of this depth in most researches can be tailored to the overall priority of simply analysing the safety of foods and/or individuals.…”

“…The occurrence of mycotoxins and associated aflatoxigenic A. flavus/ A. parasiticus in staple Ugandan foods and their derivative poultry feeds were evaluated by Sebunya and Yourtee [72]. The 54 samples of maize, peanuts, soybean and poultry feed samples taken and precultured on A. flavus/parasiticus selective agar (AFPA) were analyzed for their fungal content on a coconut agar medium under ultraviolet light with a subsequent confirmatory scrutinization for AF production in a pure culture.…”

“…Some studies in Uganda have reported the co-occurrence of AFs with some mycotoxins. In an investigation by Sebunya and Yourtee [72] on 25 samples of foods analyzed for AFB1, AFG1, zearalenone, sterigmatocystin, ochratoxin A, citrinin, vomitoxin and diacetoxyscirpenol, two samples had 20 μg/kg of AFB1. Zearalenone and vomitoxin were detected in 3 and 2 samples of maize respectively.…”

“…In this study, the highest ochratoxins and vomitoxin/deoxynivalenol content were 7.647 μg/kg and 2.606 μg/kg reported in sorghum and maize from Lamit Tumangu village, Kitgum district respectively. Baluka et al [72] compared mycotoxins and selected trace metal content of peanuts sold in selected markets in Kampala, Uganda to those traditionally prepared in homes. Market processed peanut samples (n = 33) were purchased from four St. Balikuddembe, Nakawa, Kalerwe and Bukoto markets of Metropolitan Kampala, central Uganda.…”

Uganda is predominantly an agricultural country where farming employ more than 60% of the population. Aflatoxins remain a scourge in the country, unprecedentedly reducing the value of agricultural foods and in high enough exposure levels, implicated for hepatocellular carcinoma, stunted growth in children and untimely deaths. This review synthetizes the country’s major findings in relation to the mycotoxin’s etiology, epidemiology, detection, quantification, exposure assessment, control and reduction in different matrices. It also highlights some of the management strategies for aflatoxin control that could be adopted in Uganda. Review results indicate that aflatoxins in Uganda is majorly produced by Aspergillus flavus and A. parasiticus and have been reported in maize (Zea mays L.), sorghum (Sorghum bicolor L.), sesame (Sesamum indicum), beans (Phaseolus vulgaris L.), sunflower (Helianthus annus), millet (Eleusine coracana), a bovine milk-based product, peanuts (Arachis hypogaea L.) and cassava (Manihot esculenta) with the highest content reported in cassava, beans and peanuts. The causes and proliferation of aflatoxigenic contamination of Ugandan foods have been largely due to poor pre-, peri- and post-harvest activities, poor government legislation, lack of awareness and low levels of education among farmers, agri-entreprenuers and consumers on the plague. Aflatoxin B1 is the most prevalent aflatoxin in Uganda. There is still limited research on aflatoxins in Uganda because the surveillance, reduction and control carry prohibitive costs. A few exposure assessments have been done especially in human sera and dependence on a single or a related set of foods with little diet diversity has exacerbated the risk of exposure to aflatoxins in Uganda because most of the staple foods are aflatoxin-prone. On the detection, control and reduction, these are still marginal, though some devoted scholars have devised and validated a sensitive portable device for on-site aflatoxin detection in maize as well as shown that starter cultures used for making some cereal-based beverages have the potential to bind aflatoxins. More effort should be geared towards awareness creation through training of farmers and traders in the cereal value chain as well as developing capacity to monitor aflatoxins. Vaccination against Hepatitis B and Hepatitis A should be emphasized to reduce the risk of development of liver cancer among the populace.
