There are no data on the chronic toxicity of birds available. However, the substance has no toxicological classification that is relevant for secondary poisoning (see chapter 2 Classification and Labelling). Hence, the substance is considered not to cause toxic effects if accumulated. Therefore, secondary poisoning is of no concern for this substance.
