How do viruses commonly enter humans in the context of food safety?

• A. Through airborne dust only
• B. Through dirty hands and bodily fluids
• C. Only via contaminated water
• D. Only through undercooked meat

Answer: (B)

Viruses in food safety are most often transmitted to people through hands that are dirty or carry bodily fluids. When a food handler touches food, utensils, or surfaces with unwashed hands, viruses such as norovirus or hepatitis A can transfer to the food and then be eaten. Bodily fluids—like saliva, mucus, or vomit—can contaminate food or equipment if someone coughs, sneezes, or vomits near food or handles food without proper hygiene. While other routes such as contaminated water or undercooked meat can spread viruses, the hand-to-food/hand-to-face pathway is the typical route in everyday food handling and service. Focusing on thorough handwashing, proper hygiene, and keeping sick workers away from food preparation are the most effective controls to block this entry route.
