Which fungus is most commonly linked to aflatoxin contamination in food supplies?

• A. Aspergillus flavus
• B. Penicillium chrysogenum
• C. Rhizopus oryzae
• D. Cladosporium cladosporioides

Answer: (A)

Aflatoxins are potent toxins produced by certain Aspergillus species, and they are most commonly linked to food contamination by Aspergillus flavus. This mold thrives in warm, humid conditions and often invades crops such as maize, peanuts, and tree nuts, leading to unsafe food supplies if not detected or properly stored. The other fungi listed do not typically produce aflatoxins: Penicillium chrysogenum is known for producing penicillin, not aflatoxins; Rhizopus oryzae is a common bread mold associated with spoilage but not aflatoxin production; Cladosporium cladosporioides is a widespread environmental mold without a notable role in aflatoxin contamination. So the association with aflatoxins in foods is best explained by Aspergillus flavus.
