What type of illnesses are often caused by poor personal hygiene?

Foodborne illnesses are often caused by poor personal hygiene because these illnesses typically result from the contamination of food by pathogens, such as bacteria, viruses, or parasites. If food handlers do not wash their hands properly after using the restroom, handling raw food, or touching potentially contaminated surfaces, they can transfer harmful microorganisms to the food they prepare. Proper personal hygiene practices, including regular handwashing and maintaining cleanliness, are essential for preventing the spread of these pathogens and ensuring food safety.

While the other options represent various health concerns, they are not directly linked to food safety in the same way. Infectious diseases encompass a broader range of illnesses that may not be limited to food handling, respiratory illnesses primarily relate to pathogens affecting the respiratory system, and skin diseases usually arise from contact with irritants or allergens rather than foodborne sources. Hence, foodborne illnesses remain a significant concern tied directly to inadequate personal hygiene in food service contexts.
