This study seeks a comprehensive meta-analysis of mycotoxin contaminants in animal feed consumed in the Middle East and North Africa (MENA) region. The obtained articles were reviewed, and 49 articles that investigated the contamination of mycotoxins including aflatoxins (AFs), deoxynivalenol (DON), zearalenone (ZEA), T-2 toxin, fumonisins (FUM), and ochratoxin A (OTA), in feed samples or components of animal feed in the MENA region were selected. The titles of the final articles included in the study were meta-analyzed. Necessary information was extracted and categorized from the articles, and a meta-analysis was performed using Stata software. The highest contamination was in dry bread (80%), and Algeria was the most contaminated country (87% of animal feed), with the most mycotoxins contaminating AFs (47%) and FUM (47%). The highest concentration of mycotoxins in animal feed is related to FUM (1240.01 μg/kg). Climate change, economic situation, agricultural and processing methods, the nature of the animal feed, and improper use of food waste in animal feed are among the most critical factors that are effective in the occurrence of mycotoxin contamination in animal feed in MENA. Control of influential factors in the occurrence of contaminations and rapid screening with accurate identification methods to prevent the occurrence and spread of mycotoxin contamination of animal feed seem important.

“…Aflatoxins are fully soluble in solvents such as methanol and chloroform. The presence of a lactone ring in aflatoxin molecules makes them more susceptible to hydrolysis by alkaline solutions (Azizi et al, 2012;Bankole & Adebanjo, 2003).…”

The study aims to investigate the presence of fungi and their toxins in different samples of potato chips imported from different origins. Fifteen chips’ samples were collected from the local markets of Mosul city/Iraq which included various global origins with several flavors of pepper, paprika, hot spices, and cheese. It appears that all potato chips’ samples were contaminated with fungi and mycotoxins. It was evident that Penicillium spp. were the most predominant fungi followed by Aspergillus spp. and Rhodotorella spp. came third, while Geotrichumspp and yeasts came in fourth. Potato chips from the brand Pringles was contaminated with Penicillium spp., and Geotrichum spp. at a percentage of 50, 30% respectively. The Hum Hum brand samples were contaminated with A.terrus and Penicillium spp. at 40, 30% respectively. Dream brand samples were contaminated with A.jamanicum., and Penicillium., at percentages of 30, 60% respectively. Lays1 with tomato ketchup samples were contaminated with four genera: Penicillium spp., Mucor spp., Rhodotorellaspp., and yeast with percentages of 40, 20, 10, and 10% respectively. Lays2 with French cheese variety was contaminated with the same fungi of laystype but with the addition of Aspergilli (A. versicolor and A. niger), which were 60 and 30% respectively. The Patos brand potato chips were contaminated with two Aspergilli (A.astus and A.jamanicum), at 30 and 40% respectively. Zearalenone was found to be the highest contaminant (13.81ppm) of mycotoxins followed by aflatoxins (0.26ppm). Ochratoxin was the least contaminant (0.16ppm) in the analyzed potato chips. It can be concluded that all tested potato chips’ samples showed the presence of fungi and mycotoxins. However, all mycotoxins (aflatoxin, ochratoxin, and zearalenone) in the food commodities were within the permissible limits intended for human consumption.

“…Mycotoxins are secondary metabolites produced by a wide variety of fungal species that cause nutritional losses and represent a significant hazard to the food chain [1]. Among the food-borne mycotoxins, aflatoxins and fumonisins are likely to be of greatest significance in Africa and other tropical developing countries [2] as they pose various chronic health risks [3].…”

Improper farmers' postharvest handling practices of sorghum grain coupled with adverse climatic conditions are conducive for fungal growth and toxin production. The objective of the present study was to investigate the association of farmers' sorghum grain postharvest handling practices with aflatoxin B1 and total fumonisin contamination in three districts (Babile, Haramaya and Kersa) of East Hararghe Zone, Ethiopia. A total of 90 sorghum grain samples were collected in two phases. Half of the total samples were collected from the threshing yards at the time of threshing and the other half of samples were collected from underground storage pits 5 -6 months after storage in the year 2013/14. Quantification of the mycotoxins was done using enzyme-linked immunosorbent assay (ELISA). Farmers threshed their sorghum grain either on bare ground, on cow dung smeared ground or on canvas while the underground storage pits were differently managed in all the three study districts. Variation in mycotoxin contamination levels were evidenced from sorghum grain threshed on different grounds. The highest mean (8.52 µg kg -1 grain) aflatoxin B1 and mean total fumonisin (1085.1 µg kg -1 grain) were detected from Babile sorghum grain samples threshed on bare ground. The highest total fumonisin (2002.8 µg kg -1 grain) was detected from Haramaya sorghum grain samples threshed on bare ground close to the farmers' sorghum fields. The variation was also observed in sorghum grain samples collected from the underground storage pits. High levels of aflatoxin B1 and total fumonisin were recorded from sorghum grain samples collected from bare underground storage pits in all the three study districts. Use of bare underground storage pits for sorghum grain storage showed a high risk of mycotoxin contamination. The findings of this study call for intervention strategies to be implemented by subsistence farmers to reduce the contamination by aflatoxin B1 and total fumonisin.
