“…These findings underscore the systemic nature of the issue, emphasizing its global scope rather than being limited to specific regions. Recent interventions highlighted in studies by Akullo et al [1], Ajibade et al [2], and Ansari et al [3] aim to address these challenges and improve postharvest practices to enhance food security and agricultural sustainability on a global scale. Additionally, our study found financial constraints among women groundnut farmers as a barrier to employing improved practices, echoing similar findings reported by Posey et al [37] and Martey [38] regarding constraints faced by farmers in the groundnut value chain.…”

Aims: This study sought to determine the extent of rural women's participation in managing aflatoxin contamination in the groundnut postharvest value chain. Study Design: The study employed a cross-sectional mixed-methods research design involving quantitative and qualitative methodologies. Place and Duration of Study: The study was conducted in the Chemba District in Dodoma Region, Tanzania situated at the coordinates 05°14′ 34′′ S latitude and 35°53′ 24′′ E longitude, respectively. Methodology: The primary data for the study were obtained from a random sample of 137 female groundnut farmers residing in twelve (12) villages from eight (08) wards in Chemba District. A questionnaire was used to collect quantitative data, while an FGD guide, checklist, and participant observation were employed to obtain qualitative data. Results: The findings show that women groundnut farmers participate partly in various aflatoxins-related project activities in decision making (50.36%), implementation (44.52%), benefits (59.85%), and evaluation (51.09%). Moreover, the findings of the study show that women participate in groundnut postharvest activities involving cleaning, drying, grading, sorting, processing, packing, storage, and marketing. However, the study shows that women’s participation in groundnut postharvest activities for managing aflatoxin is low. The findings also indicate that there is no statistically significant association between women's involvement in aflatoxin management and their age (χ2 = 7.800, P = 0.099), years of engagement in agriculture (χ2 = 3.556, P = 0.469), and farm size (χ2 = 2.004, P = 0.735). Additionally, a statistically significant association was observed between women's participation in managing aflatoxin and their level of education (χ2 = 12.650, P = 0.013*), as well as their marital status (χ2 = 27.550, P = 0.000***). Conclusion: The study found that rural women's participation in managing aflatoxin contamination in the groundnut postharvest value chain is critical. Hence, this study recommends developing strategies and initiatives targeting and supporting women's participation in managing aflatoxin contamination in the groundnut postharvest value chain.

“…On a global scale, the agricultural sector faces a notable challenge concerning the increasing value of groundnuts, primarily attributed to the demand for aflatoxin-free produce [1][2][3][4]. Women, who are predominantly involved in the groundnut postharvest value chain, play a crucial role in addressing this challenge [5][6][7].…”

“…Previous studies on mycotoxin research in Uganda have predominantly concentrated on aflatoxins in peanuts (Atukwase et al, 2024;Salano et al, 2024;Akullo et al, 2023;Edgar Mugizi et al, 2021) and maize (Oyesigye et al, 2024;Akullo et al, 2023b;Justus Murokore et al, 2023;Mwesige et al, 2023) due to their significant export value. Surprisingly, cassava the country's second most important food crop (UBOS, 2019), has received less attention.…”

“…Therefore, it is imperative to conduct multi-mycotoxin analysis using more efficient and effective methods like Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) (Ediage et al, 2011) in cassava to understand the contamination levels of EU regulated mycotoxins. Furthermore, there is a need to collect and analyse samples from a more national representation mainly, in dominant cassava growing and consuming households as opposed to over-sampling in the capital city and street vendors as seen in most studies (Akullo et al, 2023c;Kitya et al, 2010;Nakavuma et al, 2020;Osuret et al, 2016). Thus, this study aimed to 1) determine the occurrence, prevalence, and distribution of regulated mycotoxins (AFB1, AFB2, AFG1, AFG2, OTA, FUM, ZEN and DON) in cassava chips and flour, 2) identify the most critical points for mycotoxin contamination along the cassava value chain, and 3) assess the potential risk of dietary exposure to mycotoxin among cassava consumers through their daily dietary intake.…”

This study investigated the occurrence and distribution of EU-regulated mycotoxins (aflatoxin B1, B2, G1, G2, fumonisins B1, B2, ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), and citrinin (CIT) in cassava products, as well as assess the potential risk of Aflatoxin B1 (AFB1) exposure among cassava consumers. A total of 192 samples of cassava products (flour and chips) were analysed using LC/MS-MS. All positive samples irrespective of their origin(flour or chips), exhibited AFB1 levels exceeding the EU regulatory threshold of 5 µg/kg. The sum of fumonisins-FB1 + FB2, ZEN and DON were significantly (P < 0.05) higher in cassava flour (14.3 µg/kg; 3.71 µg/kg; 25.1 µg/kg) compared to chips (6.54 µg/kg; 1.25 µg/kg; 0.25 µg/kg), respectively. Aflatoxins G2 was not detected in all the 192 samples analysed. Cassava flour samples from farmers exhibited significantly (P < 0.05) higher mean concentrations of AFB1 (27.1 µg/kg), total aflatoxins (78.2 µg/kg) and ochratoxin A (79.6 µg/kg) in contrast to wholesalers, whose mean levels were notably lower at 8.91, 5.79 µg/kg and 2.44 µg/kg, respectively, pointing the likely critical source of mycotoxin contamination. Cassava consumers in Northern Uganda are at a higher risk of 2.06 cancer cases per 100,000 individuals per year compared to those in Eastern Uganda at 0.25. This study underscores the urgent need for improving storage practices of cassava flour at the household level, especially in Northern Uganda, recognises a shift from the conventional practice of sampling in market areas to household-level samples, and emphasises the need for analytical methods that target more than one mycotoxin.
