“…The mentioned criteria are important to be considered when buying maize or maize flour to reduce the risk of contaminated maize flour used to prepare boarding school meals for students. According to the study, post-harvest mitigation strategies for minimizing aflatoxins levels in maize and maize products include de-hulling maize and avoiding damaged or broken grains/kernels [20]. Moreover, post-harvest screening to remove contaminated seeds appears to be promising methods to reduce aflatoxin contamination.…”

Tanzania is a tropical country that lies few degrees south of the equator The coast area includes regions such as Dar es Salaam and Coastal region which are hot and humid with cooling breezes of the Indian Ocean. Awareness of society is a crucial aspect of ensuring the safety and quality of food. One of the risk factors in food safety is the presence of aflatoxin in various foods such as cereals, and groundnuts. The aim of this study was to assess the levels of awareness of aflatoxin B1 contamination in maize and maize flour used for meals in boarding secondary schools. A total of 90 respondents from 30 schools from 7 districts of the two regions were interviewed. Semi-structured questionnaires were used to collect information and the survey showed that 74.4% of the respondents were aware of aflatoxin contamination. 85.6% of respondents know that aflatoxin is found in food and only 14.4% were not aware. 74.4% were capable of selecting the correct list of food that can be contaminated with aflatoxin while 11.1% selected the wrong list. 14.4% of the respondents were unable to select the list of foods that can be contaminated with aflatoxin. These results indicate that most of them are aware of the issue of aflatoxin contamination in maize and its products which is good for reducing aflatoxin contamination in food products and its effect. An effective and broad awareness program for the society including boarding school personnel and students on good management of food for prevention of aflatoxins contamination and its health effects is necessary, as maize and its products are the most consumed grain in the study area.

“…Ten bean grains from each variety were picked at random to obtain averages of the per cent grain moisture contents using a GMK-303RS moisture meter calibrated to measure bean grain moisture content 12.5 -19.7% with an accuracy of +0.5% to obtain an average data in nine repetitions (Kimatu et al, 2014). Ten grains from each variety were picked randomly after thorough mixing.…”

“…The morphological inspection of the bean was done in order to estimate the possible aesthetic market value of each bean variety together with the phenotype variations. These included physical properties like shape, length, width and thickness (Kimatu et al, 2014). Then, the geometric mean diameter of the seeds will be evaluated using the relationship given as Dg = (LWT) 1/3.…”

The productivity of beans (Phaseolus vulgaris L) has been found to be influenced by biophysical stresses like ecological variations, genotype, climate, pests, and soil fertility. This has reduced bean productivity by 25% in some cases. Hence, research to improve bean varieties and the consequential assessment of their field performance is necessitated by global climate change scenarios. The eco-matching of genotypes in the midst of emerging issues like climate change and global warming has serious economic and food security implications. This research evaluated genotype, seasonal, ecological, and productivity variations of four bean varieties in three diverse ecological zones at the Mua Hills in Machakos County in Kenya. All the experiments were arranged in a Complete Randomized Block Design (RCBD). The research obtained data on growth (leaf numbers, plant heights, plant maturity times), seed parameters (seed water imbibition, shape, colour) and yield parameters (number of pods, pod weight, 100 seed weight) until harvesting time. Data collected were subjected to Multivariate analysis of variance (ANOVA) at P≤0.05 and means separated using the LSD significant difference test at P≤0.05. The study found that there were significant bean genotype and seasonal and eco-sensitive variation differences at P≤0.05. The economically valuable trait of 100 seed weight correlated positively with other traits in all zones. Therefore, bean varieties are season and eco-sensitive due to genotype, water stress, and current climate change scenarios. Hence, breeding experiments should endeavour to release varieties that have undergone seasonal ecological screening as exacerbated by the need for high productivity

“…Beans are one of the most common foods in schools due to its high nutritional quality in terms of percentage protein. Its high mineral content, especially iron and zinc, are advantageous in regions with high prevalence of micronutrient deficiencies such as anemia due to iron deficiency [2]. The consumption of common beans has also been reported to reduce colon and breast cancer and heart diseases [3].…”

Aims: This study sought to assess farmers’ awareness and knowledge about bean postharvest constraints and their indigenous methods to mitigate them. Cameroon. Study Design: Random interviewing of bean farmers. Place and Duration of study: Interviewed farmers of the highland savanna and humid rainforest ecological zones which are two agro-ecological zones of Cameroon respectively from January 2017 to October 2018. Methodology: A structured questionnaire was randomly distributed to 519 bean farmers in order to document their perceptions on various constraints hampering beans postharvest handling/storage and their indigenous methods of mitigating these constraints. Of these, 356 were from the highland savanna and 163 from the humid rainforest ecozones Results: Most postharvest losses in beans are caused by insects and mold/rot. Insect pests were reported by 251 (69.5%) of farmers in the highland savanna and 134 (84.8%) in the humid rain forest, while mold/rot was reported by 108 (29.9%) of the farmers in the highland savanna and 11 (6.9%) in the humid rainforest. Farmers in both agro-ecological zones lacked adequate storage facilities, as reported by 147 (40.7%) in the highland savanna and 43% (275) in the humid rainforest. Most farmers in the highland savanna 118 (39.20%) and humid rainforest 67 (43.22%) stored bean grains for 1-3 months, though farmers in the highland savanna generally stored beans longer than those in the humid rainforest. The insect infestations were controlled mainly by using conventional pesticides and local plant materials while mold was mainly managed by proper drying of the produce. Conclusions: To mitigate these constraints, an integrated approach of storing appropriately dried insect-free grains in moisture proof storage containers/facilities and judicious use of synthetic pesticides and/or proven effective botanicals should be adopted. Thus, farmers should be trained on good bean preservation methods and effective plant-based products.
