China has made eating wild animals illegal after the coronavirus outbreak

A strict ban on the consumption and farming of wild animals is being rolled out across China in the wake of the deadly coronavirus epidemic, which is believed to have started at a wildlife market in Wuhan.

Although it is unclear which animal transferred the virus to humans -- bat, snake and pangolin have all been suggested -- China has acknowledged it needs to bring its lucrative wildlife industry under control if it is to prevent another outbreak.

In late February, it slapped a temporary ban on all farming and consumption of "terrestrial wildlife of important ecological, scientific and social value," which is expected to be signed into law later this year.

But ending the trade will be hard. The cultural roots of China's use of wild animals run deep, not just for food but also for traditional medicine, clothing, ornaments and even pets.

This isn't the first time Chinese officials have tried to contain the trade. In 2003, civets -- mongoose-type creatures -- were banned and culled in large numbers after it was discovered they likely transferred the SARS virus to humans. The selling of snakes was also briefly banned in Guangzhou after the SARS outbreak.

But today dishes using the animals are still eaten in parts of China.

Public health experts say the ban is an important first step, but are calling on Beijing to seize this crucial opportunity to close loopholes -- such as the use of wild animals in traditional Chinese medicine -- and begin to change cultural attitudes in China around-consuming wildlife.

The Wuhan seafood market at the centre of the novel coronavirus outbreak was selling a lot more than fish.

Snakes, raccoon dogs, porcupines and deer were just some of the species crammed inside cages, side by side with shoppers and store owners, according to footage obtained by CNN. Some animals were filmed being slaughtered in the market in front of customers. CNN hasn't been able to independently verify the footage, which was posted to Weibo by a concerned citizen, and has since been deleted by government censors.

It is somewhere in this mass of wildlife that scientists believe the novel coronavirus likely first spread to humans. The disease has now infected more than 94,000 people and killed more than 3,200 around the world.

The Wuhan market was not unusual. Across mainland China, hundreds of similar markets offer a wide range of exotic animals for a range of purposes.

The danger of an outbreak comes when many exotic animals from different environments are kept in close proximity.

"These animals have their own viruses," said Hong Kong University virologist professor Leo Poon. "These viruses can jump from one species to another species, then that species may become an amplifier, which increases the amount of virus in the wet market substantially."

When a large number of people visit markets selling these animals each day, Poon said the risk of the virus jumping to humans rises sharply.

Poon was one of the first scientists to decode the SARS coronavirus during the epidemic in 2003. It was linked to civet cats kept for food in a Guangzhou market, but Poon said researchers still wonder whether SARS was transmitted to the cats from another species.

"(Farmed civet cats) didn't have the virus, suggesting they acquired it in the markets from another animal," he said. (CNN)
