California’s wild pigs are turning blue from the inside out. I’m talking about neon blue, blueberry blue,” wildlife control expert Dan Burton told the Los Angeles Times earlier this month. “It’s wild.”Burton saw his first blue pigs in March while butchering animals he captured near Salinas.

In 2018, a CDFW study found trace amounts of rodenticide in around 8.3 percent of wild pigs living near residential and agricultural locations with active rat control projects.
