Fungicidal / Fungistatic Activity Testing: Ensuring Protection Against Fungi and Yeasts

Fungal contamination can compromise product quality, reduce shelf life, and pose significant health risks in healthcare, food production, pharmaceutical manufacturing, and public environments. To demonstrate the effectiveness of disinfectants and antimicrobial products, manufacturers perform fungicidal and fungistatic activity testing using internationally recognized test methods. Fungicidal activity refers to the ability of a product to kill fungi, while fungistatic activity refers to its ability to inhibit fungal growth without necessarily killing the organisms. Standardized laboratory methods provide quantitative evidence of a product's efficacy, enabling manufacturers to support performance claims and comply with regulatory requirements. 


 

BS EN 1650 – Fungicidal Activity for Food, Industrial, Domestic, and Institutional Areas 

BS EN 1650 is a Phase 2, Step 1 quantitative suspension test used to evaluate the fungicidal or yeasticidal activity of chemical disinfectants and antiseptics intended for use in food processing, industrial facilities, domestic settings, and institutional environments. The test measures the reduction of viable fungi and yeasts after exposure to the disinfectant under controlled laboratory conditions. It is widely used to validate the performance of surface disinfectants, cleaning agents, and sanitation products designed for non-medical applications. 

EN 13624 – Fungicidal Activity for Medical Applications 

EN 13624 is a Phase 2, Step 1 quantitative suspension test specifically developed for assessing the fungicidal or yeasticidal activity of disinfectants used in healthcare settings. The method evaluates the effectiveness of products against clinically significant fungi and yeasts, providing reliable performance data for medical disinfectants, hand hygiene products, instrument disinfectants, and hospital surface disinfectants. Compliance with EN 13624 demonstrates that a product meets the efficacy requirements expected in medical and clinical environments. 

BS EN 14562 – Fungicidal Activity on Medical Instruments 

BS EN 14562 is a Phase 2, Step 2 quantitative carrier test that evaluates the fungicidal or yeasticidal efficacy of chemical disinfectants intended for reusable medical instruments. Unlike suspension tests, microorganisms are dried onto a carrier surface before treatment, simulating practical conditions encountered during instrument disinfection. This method provides a realistic assessment of disinfectant performance on contaminated surfaces and is widely used for validating products intended for surgical instruments, reusable medical devices, and other healthcare equipment. 

Why Standardized Fungicidal Testing Matters? 

Using internationally recognized standards ensures that antimicrobial products are evaluated under reproducible and scientifically validated conditions. These methods provide confidence that disinfectants and antiseptics perform effectively against fungi and yeasts in their intended applications, helping manufacturers demonstrate regulatory compliance, support product claims, and protect public health. 

Whether developing a hospital disinfectant, food industry sanitizer, or industrial hygiene product, selecting the appropriate fungicidal testing standard is essential to verifying product performance and ensuring effective fungal contamination control.
