What is a potential health effect of exposure to aflatoxin?

1. Respiratory irritation

2. Carcinogenic effects

3. Neurological disorders

4. Gastrointestinal distress

The correct answer is: Carcinogenic effects

Aflatoxins are toxic compounds produced by certain molds, primarily Aspergillus species, and are well-known for their potential carcinogenic effects. The World Health Organization and various health agencies recognize aflatoxins as potent carcinogens, particularly linked to liver cancer when humans are exposed to contaminated food, such as grains and nuts. Long-term exposure to aflatoxins can lead to liver damage and the subsequent development of tumors, which is why it is critical to avoid exposure to these toxins in the environment, particularly in agricultural settings. The other options, while they may represent health issues that could stem from various types of toxins or allergens, are not specifically associated with aflatoxins. Respiratory irritation can be more related to mold spores themselves rather than aflatoxins, which typically affect the liver. Neurological disorders and gastrointestinal distress also do not directly tie into the known effects of aflatoxins as prominently as carcinogenic outcomes. Therefore, the emphasis on the carcinogenic potential of aflatoxin exposure highlights the significant health risks associated with these molds and their toxins.
