Mycotoxin-contaminated food and feed in Saudi Arabia: review of occurrence and toxicity

Abstract

Introduction. Mycotoxins are reported to have a considerable impact on the health of consumers. There has been plentiful research into the effects of mycotoxins, fungi, and bacteria on the safety and quality of food and feed. This research paper reviews the literature on mycotoxins.Study objects and methods. The study focused on mycotoxins in food and feed produced in Saudi Arabia. We reviewed literature on the occurrence and health impacts of foodborne mycotoxins. We also studied the presence of mycotoxins in herbs, nuts, cereals, dried fruits and vegetables, infant formulas and baby foods, as well as dairy products. Finally, the paper offers a review of mycotoxin analysis methods. Results and discussion. The findings showed that mycotoxins attract a lot of scientific interest in Saudi Arabia. Certain types of mycotoxins (zearalenone, aflatoxins) and fungi (Aspergillus flavus, Penicillium chrysogenum, and Aspergillus niger) were common in the samples (isolates) of products tested in the Saudi regions. Furthermore, the researchers used different techniques of analysis such as the HPLC method, dilution plate method, thin layer chromatography, total plate count method, and seed-plate method to detect,identify, and isolate mycotoxins.Conclusion. Most importantly, the results showed that mycotoxins have serious health impacts on consumers and most of the contamination cases are caused by improper storage conditions and/or inappropriate handling and harvesting practices.
