Which should be used to kill the eggs of the raccoon roundworm on surfaces, caging, or substrates?

• A. Blowtorch
• B. Bleach solution
• C. Boiling water
• D. Sunlight exposure

Answer: (A)

Raccoon roundworm eggs are extremely hardy and can survive many standard cleaning methods, so relying on heat rather than chemistry is the most dependable way to inactivate them on surfaces, cages, or substrates. A blowtorch delivers direct, very high heat that quickly reaches temperatures capable of destroying the tough eggs, making it a reliable way to render any contaminated surfaces nonviable. In contrast, bleach solutions may not consistently penetrate all the eggs’ protective shell or organic matter present, sunlight exposure doesn’t provide enough heat or UV exposure to guarantee sterilization, and boiling water, while effective, is often impractical for large areas or intricate cage setups. Using a blowtorch, when done safely, provides a rapid and thorough sterilization of contaminated equipment and environments.
