In mycotoxin risk management, which scenario supports the use of binders?

• A. In feeds from high-risk ingredients or during storage conditions that favor fungi
• B. Only when mycotoxins are confirmed by testing
• C. They should be used as a substitute for good storage conditions
• D. They should be avoided entirely

Answer: (A)

Binders are a preventive tool in mycotoxin risk management: they work by binding certain mycotoxins in the gut to reduce their absorption, thereby lowering the animal’s exposure even if contaminants are present. This makes sense when feeds come from ingredients that are known to be high risk for mycotoxin contamination or when storage conditions could promote fungal growth—such as high moisture, warmth, or extended storage—because the likelihood of exposure is greater. Importantly, using binders is not dependent on confirming contamination with tests; they are meant to reduce risk proactively in situations where the chance of mycotoxin presence is elevated. They should not be viewed as a substitute for good storage, proper sourcing, and sound management—those are still essential to minimize risk. Likewise, avoiding binders altogether ignores a preventive tool that can help protect animals when risk factors are present.
