What does "secondary poisoning" refer to?

The term "secondary poisoning" specifically refers to the poisoning of predators or scavengers that consume pests which have been exposed to toxic substances, such as pesticides. When these predators or scavengers ingest the poisoned pests, they can suffer harmful effects as a result of the cumulative toxins present in the bodies of the pests. This concept highlights the ecological consequences of pesticide use beyond the targeted pests, illustrating how chemicals can affect the broader food chain and ecosystem.

Understanding this phenomenon is critical for pest management and ensuring that pesticide application does not inadvertently harm non-target wildlife, which can have significant implications for biodiversity and ecosystem health. This makes it essential for applicators to be aware of potential risks associated with pesticide use in their management practices.
