When a couple out on their ranch in Morgan Hill, California, saw a wild pig roaming the brush, they decided to shoot it and take it home for meat. After transporting the pig back home and draining its blood, the pair cut open the pig ready to skin and portion it, only to find this wild hog was hiding something quite unusual below the surface.

The pair were shocked to find that its fat was bright blue.

According to the original post, all the fat within the body was consistently stained blue. Its meat and blood however, were of normal color.

The couple have shot and eaten other wild pigs on their ranch and claim to never have found a specimen like this one.

Questions were raised whether an old copper mine in the vicinity may have caused the blue coloring, but according to the post there are only old, filled-in mercury mines in the nearby area.

Samples of the pig have been sent over to University of California, Davis to uncover the source of the unusual coloring.
