What is the primary cause of foodborne illness related to poor sanitation?

The primary cause of foodborne illness related to poor sanitation is pathogens such as bacteria, viruses, and parasites. These harmful microorganisms can contaminate food at any stage of the food supply chain, from production to preparation. When food that is contaminated with pathogens is consumed, it can lead to illness.

Good sanitation practices are crucial in preventing the spread of these pathogens. This includes proper handwashing by food handlers, maintaining clean cooking and food preparation surfaces, and ensuring that food is stored and cooked at safe temperatures. While ingredients, cooking methods, and storage techniques are all important factors in food safety, it is the actual presence of infectious agents that directly leads to foodborne illness. Understanding the role of pathogens is essential for implementing effective sanitation practices that protect public health.
