Residuals from which type of disinfectant can be toxic?

• A. Glutaraldehyde
• B. OPA
• C. Sodium hypochlorite
• D. Hydrogen peroxide

Answer: (B)

Residuals from ortho-phthalaldehyde (OPA) can indeed be toxic. OPA is a high-level disinfectant used in the healthcare setting, particularly for flexible endoscopes. It is well known for its effectiveness in killing a wide range of pathogens, including bacteria, viruses, and fungi. However, the residuals that may remain on medical instruments after disinfection can pose a risk to both patients and healthcare workers if not adequately rinsed off. Toxicity concerns are particularly relevant in the context of prolonged exposure to OPA, which can cause skin, eye, and respiratory irritation. For this reason, strict protocols must be followed in reprocessing flexible endoscopes to ensure that all residues are removed and that instruments are safe for patient use. Proper cleaning, rinsing, and drying practices are essential to mitigate any potential risks associated with OPA residuals. Understanding the implications of disinfectant residuals is critical for ensuring patient safety and compliance with infection control standards.
