What feature must an outdoor waste receptacle have to minimize contamination?

• A. A Visible Sign
• B. A Wide Opening
• C. A Safe Lock
• D. Tight-Fitting Lid

Answer: (D)

Keeping waste securely contained is essential to prevent contamination around the dining area. A lid that fits tightly closes the receptacle, blocking access by pests like insects and rodents, and keeping rain, wind, and litter from escaping. This directly reduces the chances of waste contaminating nearby surfaces, water, or food-contact areas and also helps control odors that attract more pests. A visible sign doesn’t prevent access or exposure. A wide opening invites pests and debris to escape or blow away. A lock may help with security, but it doesn’t guarantee a tight seal against pests and weather. So, the feature that best minimizes contamination is a tight-fitting lid.
