Mold Remediation Certification Practice Exam

Which of the following is an example of a carcinogenic mycotoxin?

1. Aflatoxin

2. Penicillin

3. Stachydrine

4. Chlorophyll

The correct answer is: Aflatoxin

Aflatoxin is recognized as a carcinogenic mycotoxin because it is produced by certain molds, particularly Aspergillus species, which can contaminate agricultural products, especially grains and nuts. Aflatoxins are known for their potential to cause cancer in humans and animals and are classified as Group 1 carcinogens by the International Agency for Research on Cancer (IARC). This classification indicates that there is sufficient evidence of carcinogenicity in humans. The significance of recognizing aflatoxins lies in their widespread impact on food safety and public health, especially in areas where food preservation practices may be lacking. Understanding aflatoxins helps in implementing measures to prevent contamination and exposure, thereby reducing cancer risks. In contrast, penicillin is an antibiotic and does not have any carcinogenic properties. Stachydrine, while it might be related to some mold strains, is not classified as a carcinogenic mycotoxin. Chlorophyll is a pigment found in plants and is not associated with mold or mycotoxins, nor does it exhibit carcinogenic properties. Therefore, aflatoxin stands out as the primary and well-documented example of a carcinogenic mycotoxin.
