Final answer:
Pesticides are not a biological hazard that causes foodborne illness but are chemical hazards. Foodborne illnesses are mainly caused by bacteria, molds, viruses, and parasites.
Step-by-step explanation:
The correct answer to the question is e. Pesticides. Biological hazards that cause foodborne illness include bacteria, molds, viruses, and parasites. These microorganisms can contaminate food and cause various illnesses in humans. Examples of bacteria include Salmonella and Campylobacter jejuni. Viruses such as norovirus also pose significant risks, and parasites like Taenia solium can be transmitted when inadequately cooked animal tissues are consumed. On the other hand, pesticides are classified as chemical hazards, not biological ones, and thus do not belong in this list.
