When spores may be present, disinfection must shift to products that are specifically labeled as sporicidal and require a longer contact time. Spores have tough coats and a dormant state that make them highly resistant to many ordinary disinfectants, so simply using a common cleaner or sanitizer isn’t enough. To reduce the risk of transmission from spores, use a sporicidal disinfectant (such as certain chlorine-based solutions, hydrogen peroxide–based products, peracetic acid, or other approved sporicides) and follow the product’s directions for dwell time so the surface remains wet long enough for the agent to inactivate spores. Cleaning first to remove organic matter is also important, because soil can shield spores from disinfectants. In contrast, alcohol-based sanitizers and many routine disinfectants are not reliably sporicidal and should not be relied upon for environmental surfaces when spores might be present.
