“…Among cereals, rice and corn are mostly contaminated by AFs in natural conditions due to changes in agricultural practices. The occurrence of AFs is common in wide varieties of food include peanuts, nuts, figs, corn, rice, spices, and dried fruits [52]. It has been shown that among the tested cereals, 37.6% were at least contaminated by any of the AFs [53].…”

BACKGROUND: Aflatoxins (AFs) are fungal secondary metabolites produced by Aspergillus flavus. They contaminate of dietary food with AFs is a worldwide problem that affects both food safety and agricultural economies. AIM: The aim of this study was designed to investigate the AFs contents of human food commodities mostly consumed in Jeddah, Saudi Arabia. METHODS: The study was designed in vitro, contents in six food categories. A total of 288 samples were collected from 78 different markets in Jeddah. AFs were determined by high-performance liquid chromatography with fluorescence detector using immunoaffinity column clean-up. RESULTS: The results indicated that the incidence rate 27.3% of nut samples collected from Jeddah, were contaminated with AFB1, AFB2. The concentrations of AFs (AFB1, AFB2, AFG1, and AFG2) were ranged from 0.19–482.4, 0.09–3.34, 0.19–87.1, to 0.09–579 μg/kg in the nut samples. CONCLUSION: The results demonstrate the importance of routine monitoring of AFs contamination in various dry foods for human consumed should be performed regularly and the nuts contained high levels of AFs. The legal regulations must be unauthorized for human consumption to control the health risks associated with AFs.

“…The occurrence of AFs is common in wide varieties of food and feed (Table 1). Some of the most affected food and feed include peanuts, nuts, figs, corn, rice, spices and dried fruits (Martinez-Miranda et al, 2019). It has been shown that among the tested cereals, 37.6% were at least contaminated by any of the AFs (Andrade and Caldas, 2015).…”

Aflatoxins produced by the Aspergillus species are highly toxic, carcinogenic, and cause severe contamination to food sources, leading to serious health consequences. Contaminations by aflatoxins have been reported in food and feed, such as groundnuts, millet, sesame seeds, maize, wheat, rice, fig, spices and cocoa due to fungal infection during pre- and post-harvest conditions. Besides these food products, commercial products like peanut butter, cooking oil and cosmetics have also been reported to be contaminated by aflatoxins. Even a low concentration of aflatoxins is hazardous for human and livestock. The identification and quantification of aflatoxins in food and feed is a major challenge to guarantee food safety. Therefore, developing feasible, sensitive and robust analytical methods is paramount for the identification and quantification of aflatoxins present in low concentrations in food and feed. There are various chromatographic and sensor-based methods used for the detection of aflatoxins. The current review provides insight into the sources of contamination, occurrence, detection techniques, and masked mycotoxin, in addition to management strategies of aflatoxins to ensure food safety and security.

“…Oilseed crops such as maize and peanut are crops commonly infected by A. flavus and subsequently contaminated with carcinogenic aflatoxins and numerous other toxic secondary metabolites (SMs). Other crops such as rice, tree nuts, figs, spices, and dried fruits are also prone to aflatoxin contamination either pre- or post-harvest (reviewed in [ 4 , 5 ]). Computer models of future climate change scenarios predict significant increases in aflatoxin contamination due to environmental conditions more favorable for A. flavus growth and survival [ 6 ].…”

Aspergillus flavus (A. flavus)-mediated aflatoxin contamination in maize is a major global economic and health concern. As A. flavus is an opportunistic seed pathogen, the identification of factors contributing to kernel resistance will be of great importance in the development of novel mitigation strategies. Using V3–V4 bacterial rRNA sequencing and seeds of A. flavus-resistant maize breeding lines TZAR102 and MI82 and a susceptible line, SC212, we investigated kernel-specific changes in bacterial endophytes during infection. A total of 81 bacterial genera belonging to 10 phyla were detected. Bacteria belonging to the phylum Tenericutes comprised 86–99% of the detected phyla, followed by Proteobacteria (14%) and others (<5%) that changed with treatments and/or genotypes. Higher basal levels (without infection) of Streptomyces and Microbacterium in TZAR102 and increases in the abundance of Stenotrophomonas and Sphingomonas in MI82 following infection may suggest their role in resistance. Functional profiling of bacteria using 16S rRNA sequencing data revealed the presence of bacteria associated with the production of putative type II polyketides and sesquiterpenoids in the resistant vs. susceptible lines. Future characterization of endophytes predicted to possess antifungal/ anti-aflatoxigenic properties will aid in their development as effective biocontrol agents or microbiome markers for maize aflatoxin resistance.
