Which of the following statements best fits the rule about contamination from dirt?

• A. After handling ANYTHING dirty, wash your hands
• B. After handling clean vegetables only
• C. Only wash if you smell something
• D. Wash only before cooking

Answer: (A)

Hand hygiene after touching dirt is the main defense against contamination. Dirt can hide germs, and those germs can move from your hands to foods, utensils, and surfaces even if you don’t notice anything wrong. Washing your hands after handling anything dirty stops that transfer at the source, reducing the risk of spreading bacteria to food and prep areas.

This approach is better than saying you only wash after handling clean vegetables, which ignores the moments when you’ve touched dirty items that can contaminate foods you’re about to work with. It’s also not reliable to wash only if you smell something—odor isn’t a trustworthy indicator of contamination. And washing only before cooking leaves plenty of chances for contamination to spread during preparation or handling of dirty items.
