Wild Pigs Glow Neon Blue From Rat Poison
13 Mar
Summary
- Wild pigs in California found with neon blue flesh in 2025.
- Rodenticide, diphacinone, causes internal bleeding and discoloration.
- Pesticides harm wildlife, ecosystems, and human health.

In 2025, hunters in California encountered a disturbing sight: wild pigs with flesh dyed a shocking neon blue. Investigations revealed this dramatic discoloration was caused by diphacinone, a common rodenticide. This anticoagulant poison works by inhibiting vitamin K, leading to fatal internal bleeding in animals.
This chemical, often dyed blue for identification, has faced stringent controls in California since 2024. Diphacinone poses a significant risk not only to targeted rodents but also to non-target wildlife, including raptors and endangered species, through direct exposure or secondary poisoning. Predators consuming poisoned animals, such as wild pigs, can also be affected.
Pesticides like diphacinone have far-reaching consequences, impacting wildlife populations and raising concerns about human health. Studies link various pesticides to serious health issues. Integrated pest management, utilizing safer strategies, is being promoted as an alternative to reduce these widespread environmental and health threats.
