Which statement about blue dye in enteral feedings is correct?

• A. It prevents aspiration
• B. Its use is highly sensitive
• C. It should be added only in small amounts
• D. It is no longer recommended for detection of aspiration of enteral formula

Answer: (D)

Blue dye in enteral feedings is no longer recommended as a method to detect aspiration. The idea was to rely on a colored dye to reveal when formula is entering the airway, but this approach is unreliable—small amounts of aspirated feed may not produce a visible color change, and blue secretions can be mistaken for aspiration or occur for other reasons, leading to false positives or negatives. Because of these limitations and potential dye-related adverse effects, current practice does not endorse using blue dye to detect aspiration; instead, detection relies on careful clinical assessment and, when needed, objective swallow studies or imaging. The other statements don’t fit because the dye does not prevent aspiration, is not considered highly sensitive, and there’s no recommended practice to add it in small amounts.
