Aflatoxin is an example of a mycotoxin. Aflatoxin B1, a frequent food contaminant, causes liver cancer. A concern is also contaminated herbal medicines with microorganisms and fungal toxins, including aflatoxin. Those samples are measured for aflatoxin contamination. Above 75 percent humidity threshold, fungal molds that release dangerous aflatoxin can form. Damage or early splits can lead to aflatoxin contamination. The liver is the most susceptible organ to aflatoxin B toxicity. The largest economic lost caused by this pathogen is a result of aflatoxin production. The center succeeded in producing toxic fungus, including aflatoxin. Occupational exposure to aflatoxin B has also been reported in swine and poultry production. Other causes include aflatoxin, non-alcoholic fatty liver disease and liver flukes. Dermal exposure to this aflatoxin in particular environmental conditions can lead to major health risks. However the most toxic type of aflatoxin, B, can permeate through the skin. Young piglets, ducklings, and turkeys exposed to high doses of aflatoxin become sick and die. Aflatoxin exposure can lead to the development of HCC.
