Pinworm eggs are usually destroyed by heat or dessication.

• A. True
• B. False
• C. Not enough information
• D. Sometimes true depending on conditions

Answer: (B)

Pinworm eggs are highly persistent in the environment because their outer shell protects them from drying and many common cleaning methods. Because of this resilience, simply exposing contaminated materials to ordinary heat or letting them desiccate does not reliably destroy all eggs. High-temperature, moist heat sterilization (such as autoclaving or prolonged, validated heating) is required to ensure destruction, and drying alone is not sufficient. In practice, rely on proper sterilization or validated chemical disinfection methods to eliminate pinworm eggs rather than assuming heat or desiccation will do so.
