Which of the following is not a common cause of foodborne illnesses?

Oils are not typically associated with causing foodborne illnesses, unlike bacteria, viruses, and pathogens, which are well-documented contributors to food safety concerns. Bacteria, such as Salmonella and E. coli, can multiply in food and cause illness through contaminated food or inadequate cooking processes. Viruses, like Norovirus and Hepatitis A, can also spread through contaminated food or surfaces and lead to illness. Pathogens encompass both bacteria and viruses and are a major focus of food safety practices to prevent outbreaks.

In contrast, while oils are essential in cooking and food preparation, they do not themselves cause foodborne illnesses. The primary issues with oils can arise from improper storage that leads to rancidity or spoilage, but these conditions do not involve the pathogenic organisms that lead to foodborne diseases. Therefore, identifying oils as the option that is not a common cause of foodborne illnesses is accurate and reflects a clear understanding of food safety principles.
