Although bleach is an effective disinfectant against many pathogens, the particular strain Clostridioides difficile, commonly referred to as C. diff, is known for its resistance to many conventional cleaning agents. The Centers for Disease Control and Prevention (CDC) recommends using an Environmental Protection Agency (EPA)-registered disinfectant with a C. diff claim or a dilute bleach solution, typically 1:10 (one part bleach to nine parts water), for surfaces potentially contaminated with C. diff spores. The correct answer is true; a 1:10 bleach solution is indeed recommended for this use, highlighting the importance of knowing specific disinfection protocols for different types of pathogens.
