Game hunters found startlingly 'neon blue' flesh inside wild pigs in California in 2025, prompting advisory statements about potential contamination.
"I'm not talking about a little blue," Dan Burton, owner of a wildlife control company, told Salvador Hernandez at The Los Angeles Times.
"I'm talking about neon blue, blueberry blue."
An investigation by local authorities found that the dramatic color change was caused by rodenticide poisoning, prompting them to issue a warning throughout Monterey County.
Rat poisons containing the chemical compound diphacinone are often sold dyed blue for identification. The compound's use has been highly restricted in California since 2024.
