Wildlife officials are worried wild pigs have become exposed to rodenticide, contaminating the animals and turning their meat and fat blue.

In an email to SFGATE, Fish and Wildlife pesticide investigations coordinator Ryan Bourbour said that the trapper observed the wild pigs eating directly from rodenticide bait stations. The scope of the contamination appears extensive across the southern part of Monterey County and along the Salinas River, according to KSBW-TV.
