Which of these is a common sign of foodborne illness?

A common sign of foodborne illness is nausea and vomiting. These symptoms often result from ingesting contaminated food or beverages that harbor pathogens, such as bacteria, viruses, or parasites. When the body detects harmful substances in the digestive system, it reacts by trying to expel them, which can manifest as nausea and vomiting.

These symptoms are particularly critical in food safety as they can indicate the presence of a serious health threat, prompting immediate attention and action to prevent further spread or consumption of contaminated food. Understanding the typical signs of foodborne illness, like nausea and vomiting, is essential for food handlers to ensure they can identify issues quickly and take necessary precautions to protect public health.

Increased appetite, frequent headaches, and excessive energy do not typically align with the indicators of foodborne illnesses, as these conditions generally highlight well-being rather than adverse reactions to food.
