“…As for the processing of fish, one of the objectives of which is to reduce postharvest losses and ensure the food security of populations, does not always guarantee the quality of the fish [2,3]. It is the source of certain harmful effects on the health of processors and consumers as well as on the environment [4][5][6]. But being a very perishable commodity because of its very high protein and water content, fish is subject to enormous post-harvest losses due to mold [7].…”

Introduction: Fresh and smoked fish are widely consumed in Côte d'Ivoire as everywhere in West Africa. However, these foodstuffs, due to certain processing conditions, are likely to be contaminated by molds that produce dangerous mycotoxins. Objective: This study aimed to isolate and identify fungal strains contaminating fresh and smoked fish from the Sassandra River in Côte d'Ivoire. Place and Date of the Study: Sampling was carried out in various processing sites around the Sassandra River, particularly in the towns of Soubré and Guessabo. The microbiological analysis was carried out at Jean Lorougnon Guédé University in Daloa (Ivory Coast). Methods: A total of 108 samples of fresh and smoked fish were collected. Isolation and purification of fungal strains were carried out on Sabouraud medium with chloramphenicol. The identification of isolated strains was made on the basis of morphological and cultural criteria. Results: A total of 126 fungal strains were isolated, including 87 from the Guessabo samples and 39 from the Soubré samples from 54 fresh fish and 54 smoked fish. The predominant species were Aspergillus of the Glaucus group (39%), Aspergillus niger (36%) and Penicillium sp. (25%). Conclusion: This study shows that fresh and smoked fish from the Sassandra River in Côte d'Ivoire are contaminated by several strains of molds, some of which produce mycotoxins that can cause illness in consumers depending on their concentrations. It would therefore be appropriate to improve processing techniques.

BACKGROUND Research into environmentally friendly alternatives to conventional plant protection products, to promote sustainable agriculture and healthy food, is strongly encouraged. RESULTS In this context, 20 naturally occurring terpenoids and phenolic compounds were selected and evaluated in vitro as crop protection compounds against Zymoseptoria tritici, the causal agent of Septoria tritici blotch of wheat. After selection of the most active compounds, some hemisynthetic modifications were conducted to modify their lipophilicity. These modifications led to the discovery of sesamol esters as promising antifungal agents, with IC50 around 10 μg/mL and a total absence of cytotoxicity against human cells. CONCLUSION These sesamol‐based derivatives should be selected for further evaluations in planta to validate their use as wheat crop protection agents. Moreover, the importance of a balanced hydrophily/lipophilicity ratio should be further studied. © 2021 Society of Chemical Industry
