What are ochratoxins primarily produced by?

• A. Fusarium and Myrothecium
• B. Aspergillus and Penicillium
• C. Clostridium and Salmonella
• D. Lactobacillus and Streptococcus

Answer: (B)

Ochratoxins are primarily produced by certain molds, specifically species of Aspergillus and Penicillium. These fungi are known to thrive in various agricultural products, including grains and coffee, and can contaminate food supplies under unsuitable storage conditions, typically involving high humidity and warmth. Aspergillus ochraceus, in particular, is one of the main producers of ochratoxin A, which poses significant health risks, including nephrotoxic effects and potential carcinogenicity in humans. Penicillium species can also produce ochratoxins, adding to the overall concern regarding food safety. Understanding the origins of these toxins is crucial for preventing ochratoxin contamination in food products and ensuring public health safety. The other groups mentioned, such as Clostridium and Salmonella, are primarily known for causing different types of foodborne illnesses, and Lactobacillus and Streptococcus are generally associated with fermentation processes and do not produce ochratoxins. Thus, the focus on Aspergillus and Penicillium as major sources of ochratoxins is accurate and essential for food safety management.
