A wild boar with a 'blue color' on its back has been observed in California, raising concerns.
According to the British daily Daily Mail on the 18th (local time), authorities are on high alert for the possibility of contamination as bizarre cases have been reported of wild boars' flesh and fat turning 'fluorescent blue' in California.
Reports have been received that wild boars displaying fluorescent blue color have been discovered since 2015. The Daily Mail reported that this phenomenon is likely due to a substance called 'diflufenican.'
'Diflufenican' is a dye rodenticide used to control populations of rats and squirrels, and it has been suggested that wild animals like wild boars have turned blue after eating rodents affected by this pesticide.
The area of the body that changes color is primarily the 'fat' part of the wild boar.
Authorities have advised that the meat of animals showing signs of 'blue pigment' deposits should never be eaten and should be reported, as this substance can cause severe internal bleeding.
According to research findings, even with cooking, such as heating, humans can be exposed to the side effects of chemicals by consuming animals that have been poisoned.
Last year, U.S. authorities enacted a law banning the use of diflufenican to prevent wildlife from being exposed to toxic substances.
