Which of the following is a common cause of foodborne illness?

Improper food storage is a common cause of foodborne illness because it creates an environment where harmful bacteria can thrive. For instance, storing food at temperatures that are too high or too low can allow pathogens to multiply. Foods that are not kept at safe temperatures can lead to spoilage and bacterial growth, resulting in illness when consumed. Proper storage practices, such as refrigeration and maintaining food at safe temperatures, are essential to prevent these risks.

Using fresh herbs in cooking, cooking food at appropriate temperatures, and regularly cleaning utensils are generally safe practices that contribute to food safety rather than causing foodborne illnesses. In fact, these actions are essential components of safe food handling and preparation.
