An investigation of five fur farms in China housing foxes, raccoon dogs and mink found a high risk of diseases developing that could jump from animals to humans, said animal protection group Humane Society International who conducted the study at the end of 2023.
The farms in China’s northern Hebei and Liaoning provinces each held between 2,000 and 4,000 animals in intensive conditions, including in close proximity to poultry, HSI said.
Alastair MacMillan, a visiting professor at Surrey University’s Veterinary School, said the high stocking density of the animals facilitates the rapid spread of viruses on droplets from one to another, and potentially to humans.
“The rapid circulation and mixing of different strains of virus from animal to animal facilitates their adaption to a mammalian host, the development of mutant strains of concern and a greater likelihood of a threat of human infection.”
