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

Multiple wild pigs' tissue turned blue in the Monterey County area after pesticide bait exposure, the California Department of Fish and Wildlife said.

Wild pigs found to have blue meat and fat show signs of having eaten rat poison, California wildlife officials warned. In March, a wildlife trapper reported discovering the dyed tissue in wild pigs caught in Monterey County, the state Department of Fish and Wildlife said in a July 30 news release.
