Hoax or Fact:
Fact with some missing information.
Few pictures floating around internet space claim to show a mysterious wild pig with bright blue fat surrounding its meat, allegedly discovered after being shot by ranchers in Morgan Hill, California. The pictures sparked plenty of conversation on social media, for their authenticity and the reasons why the pig fat is bright blue in color. As detailed below, the pictures showing a wild pig with bright blue color covering its fat are real. The possible reason for it is thought to be because of consuming food with rodent poison to which blue dye is added.
About the Incident
In September 2015 Reddit user GlendilTEK posted the images on Imgur website imgur.com with a brief explanation that the bizarre discovery happened at their in-laws' Morgan Hill ranch in California. Notably, the meat and blood of the pig shot dead were of normal color, but the fat is stained bright blue all the way through the pig. After viewers were sceptic about the pictures, the user added few other pictures showing the wild pig having inner fat stained bright blue. The user suggested that such blue pigmentation is often caused from copper poisoning, but also said the ranch only had some old mercury mine shafts that they have filled in. He said the ranchers were startled at the discovery of blue fat pig for the first time. While others suggested theories like infection, genetic defect, rat poison or a possible contamination from a chemical with blue dye in it, the samples of the blue pig fat were sent to University of California Davis for testing.
Expert Opinion on Pig with Blue Fat
Explaining the story, Business Insider website businessinsider.com reports the opinion of Robert Poppenga, a veterinarian and toxicologist at the Animal Health and Food Safety Lab at UC Davis as told to Tech Insider. The expert said that the blue pigment visible in pig fat is almost certainly from a blue dye put into an anticoagulant bait formulation (otherwise known as rat poison), adding that they could not verify it analytically because the lab only received a sample from the animal - not from the likely rodenticide source. He also mentioned that UC Davis has seen a similar case in a feral pig few years ago, when the animal ate Diphacinone (used as a rodenticide) and blue dye from baited grain. The hypothesis of Robert Poppenga was also backed up by Stella McMillin, a senior environmental scientist from the Wildlife Investigations Laboratory in the California Department of Fish and Wildlife. When animals eat, or are exposed to anticoagulant rodenticide (rat poison), the pigmentation of their fat can change. So possibly the wild pig shot at California Ranch too might have been exposed to such anticoagulant rodenticide and blue dye.
