“…Shundo et al [24] and Lewis and Schneider [25], proved that, aflatoxins B1 and G1 occurred most frequently and in high quantities in fruit and their products. [26] and Saadullah and Samir [20] proved that, A. flavus and A. parasiticus which grow on many agricultural commodities are the most significant aflatoxigenic fungi. Abyaneh et al [27] and Rodrigues et al [28] found that, A. parasiticus strains are usually strongly aflatoxigenic, producing both AFBs and AFGs.…”

“…Rhizopus nigricans, R. stolonifer and Penicillium spp. Saadullah and Samir [20] isolated thirty one species assigned to 14 genera from dried figs. Aspergillus was represented by 12 species and showed the widest diversity among all recorded genera, followed by Penicillium which represented by five species.…”

Over 25 to 30 percent loss of fruits is caused by fungal diseases. Several fungi invade and damage fig fruits and alter all the biochemical contents affecting the quality. So this study aimed to survey of mycoflora and mycotoxins affecting fig fruit quality in Egypt. Fig fruits from five different orchards in different localities in Egypt were analyzed for mycological examination and mycotoxins association. Three organic acids i.e. Ascorbic acid, Benzoic acid and Citric acid were evaluated as alternative fungicides against the selected toxigenic fungus. Four hundreds eighty fungal isolates were isolated from five different orchards of Fig fruit samples. Ten fungal species were identified. These are Alternaria alternata (Fr.) Keissler, Aspergillus niger Van Tiegh, A. parasiticus, A. flavus Link., A. terreus Thorn, Botrydiplodia theobromae, Cladosporium sp., Penicillum sp., Rhizopus stolonifer and Fusarium sp.. All tested fungi i. e. Alternaria alternata, Aspergillus flavus and A. parasiticus were found to decrease fruit quality which reduces the fruit weight (g), size (cm 3 ), length (cm) and diameter (cm 3 ), total soluble solids (TSS %), and increase the moisture percent of tested samples. Only five isolates of A. parasiticus gave a positive reaction for aflatoxins production. It could be concluded that, all tested organic acids substrates used i.e. Ascorbic acid, Benzoic acid and Citric acid (as an alternative fungicide) had antifungal effects against A. parasiticus which were able to reduce significantly the disease incidence of fig fruits compared with untreated control.

“…A study by Asia and Samir (34) showed apricot and fig as the highest abilities to produce aflatoxin. Similarly, another study (35) found the highest concentration of AFB1 in apricot and fig (138.28 µg/kg, 46.18 µg/kg) respectively.…”

Introduction:The present study aims to determine the contamination of eighteen samples from different nuts and dried fruits from the markets of Mosul and Duhok city.Materials and Methods: This study included samples of local and imported nuts and dried fruits. Results:The study showed different genera of contaminant fungi such as Alternaria, Penicillium, and Aspergillus species which are very common fungi associated with samples. The most fungal contamination was found in pistachio and black raisins, followed by balahsisi, taffy raisins, yellow raisins, dried apricot and peanut with shell. A total of nine species of Aspergillus were isolated on (potato dextrose agar, malt extract agar and dichloran rose bengal agar) media A. niger, A. flavus, A. fumigatus, A. tamarii, A. aculeatus, A. parasiticus, A. oryzae, A. japonicus, A. ochraceus were detected from all types of nuts and dried fruits samples. The most frequent species were A. niger followed by A. flavus and A. fumigates with percentage frequencies of 45.2%, 20.3% and 13.9% respectively. The ability of toxicogenic fungi to produce AflatoxinB1 by ELISA test of Sunlong corporation in nuts and dried fruits samples ranged from 94.8 to 136.4 µg/kg, with the highest levels of ability to produce AflatoxinB1 in nuts samples (peanut with shell, sunflower seeds and walnut) at levels 135.8, 129.0, and 128.9 µg/kg respectively, while in dried fruits samples the highest ability to produce AflatoxinB1in dried apricot, taffy raisins and yellow raisins was at levels136.4,123.1 and 118.0 µg/kg, respectively.Conclusion: we conducted the fungal contamination and quantitative content of aflatoxin B1 in nuts and dried fruits notably those sold openly in food shops.

The aim of this research is to isolate and identify the fungi associated with infected fig fruits in different Governorates in Egypt (Alexandria, Qalubia, Ismailia, Giza and Sinai), as well as study their ability to produce aflatoxins. Samples of fresh fig fruits were collected, small slices of peel were disinfected and transferred to Petri-dishes containing PDA medium and incubated at 25ºC for 5 days. The higher total fungal counts as 201, 111 and 102 isolates were recorded on the samples from Qalubia, Sinai and Ismailia, respectively and the least as 48 isolates was found on samples from Giza. Seven fungal genera were identified (Alternaria tenuis, Aspergillus flavus, A. niger, A. parasiticus, A. terreus, Botryodiplodia theobromae, Cladosporium sp., Fusarium solani, Penicillium sp. and Rhizopus sp.). All Aspergillus genera produced mycotoxins except Aspergillus terreus which was negative producer of mycotoxins (AFB 1 , AFB 2 , AFG 1 and AFG 2 ).
