Unexpected exposure to rodenticide is turning California’s wild pigs blue, state authorities say. “I’m not talking about a little blue,” Dan Burton, owner of a wildlife control company in Salinas, California, told The Los Angeles Times. “I’m talking about neon blue, blueberry blue.”

"I'm not talking about a little blue, I'm talking about neon blue, blueberry blue," said the wild pig trapper who made the discovery.

Predators and people who eat animals that were poisoned by diphacinone can suffer "secondary exposure" to the poison because the substance can remain for a time in the organs and tissue of the animal.
