In the current times of climate change, the intense use of insects as a protein source is gaining popularity worldwide, and will likely contribute to increased nutrient intake in food and feed due to its nutritional, ecological, nutraceutical, and medicinal potential. Ancient traditional consumption of wild-harvested insects in Africa is a valuable but diminishing resource. There is a need for improved technology in insect rearing to match production with the current population pressure since we can no longer depend on wild collection. The current legislation within the European Union opens a pathway towards acceptance, increased consumption, and marketing of edible insects, which already had a big role in African nutrition as a portion of seasonal food. Food security and expensive animal protein sources are a setback in Africa and there is a need to search for alternative sources to curb malnutrition. Insect use in animal feed is gaining momentum in pig, fish, pet, and poultry feed. To meet the rising demand for insect protein in animal feed, it calls for new ways to increase availability while addressing food quality, safety, and environmental sustainability. Apart from their importance as a source of nutrients, insects help to recycle organic waste, and the remaining portion can be used in plant protection and as a soil modifier. This review, therefore, undertakes exploration and outlook on the ancient utilisation of edible insects in Africa, current efforts to improve through farming, and the challenges faced with the hope that traditional practices will shape the future of the edible insect industry.

Fungi of the genus Alternaria are ubiquitous in the environment. Their mycotoxins can leach out of contaminated plants or crop debris into the soil entering the plant via the roots. We aim to evaluate the importance of this entry pathway and its contribution to the overall content of Alternaria toxins (ATs) in wheat plants to better understand the soil–plant-phytopathogen system. A hydroponic cultivation system was established and wheat plants were cultivated for up to two weeks under optimal climate conditions. One half of the plants was treated with a nutrient solution spiked with alternariol (AOH), alternariol monomethyl ether (AME), and tenuazonic acid (TeA), whereas the other half of the plants was cultivated without mycotoxins. Plants were harvested after 1 and 2 weeks and analyzed using a QuEChERS-based extraction and an in-house validated LC–MS/MS method for quantification of the ATs in roots, crowns, and leaves separately. ATs were taken up by the roots and transported throughout the plant up to the leaves after 1 as well as 2 weeks of cultivation with the roots showing the highest ATs levels followed by the crowns and the leaves. In addition, numerous AOH and AME conjugates like glucosides, malonyl glucosides, sulfates, and di/trihexosides were detected in different plant compartments and identified by high-resolution mass spectrometry. This is the first study demonstrating the uptake of ATs in vivo using a hydroponic system and whole wheat plants examining both the distribution of ATs within the plant compartments and the modification of ATs by the wheat plants.
