Technol. The liver is the main organ affected by the toxic effects of aflatoxin. The foods and crops most likely to be contaminated with aflatoxin include: Experts believe that the biggest threat of aflatoxin to human health globally is the contamination of corn, since its such a widely-consumed, staple crop in many parts of the world that people depend on. Exposure to this toxin poses serious hazards to human health (Umoh et al., 2011). Pollution from AFB1 causes serious economic and health issues worldwide because it causes strong mutagenicity and carcinogenicity in humans and animals. A 2015 study published in the International Journal of Food Microbiology found strong support for soaking, sprouting and fermenting grains, nuts and legumes due to how lactic acid and other beneficial types of bacteria wind up minimizing aflatoxins effects. 58, 954958.

If multiple organs are damaged, treatment is geared toward supporting these organs. Proc. An ELISA method previously used for aflatoxin serum albumin in human blood was used to analyse bovine serum samples (n = 22) collected from dairy cattle during an aflatoxin mitigation study in Kenya. Biological control of aflatoxin production in crops in the US has been approved by the Environmental Protection Agency and two commercial products based on atoxigenic A. flavus strains are being used (Afla-guard and AF36) for the prevention of aflatoxin in peanuts, corn, and cotton seed (Dorner, 2009). Trail, F., Mahanti, N., Rarick, M., Mehigh, R., Liang, S. H., Zhou, R., et al. 29, 326. AFT-B1 reduced anti-inflammatory cytokine IL-4 expression, but increased the pro-inflammatory cytokine IFN- and TNF- expression by NK cells. 110, 147155. Aflatoxins are the most researched group of mycotoxins due to their carcinogenic and toxic effects in laboratory animals and livestock (Jha et al., 2013; Rotimi et al., 2017), as well as their acute and chronic hepatocarcinogenic and toxicological effects in human beings (Asim et al., 2011; Kew, 2013).
