Poor welfare of animals on sale in Huanan seafood market: (a) King rat snake (Elaphe carinata), (b) Chinese bamboo rat (Rhizomys sinensis), (c) Amur hedgehog (Erinaceus amurensis) (the finger points to a tick), (d) Raccoon dog (Nyctereutes procyonoides), (e) Marmot (Marmota himalayana) (beneath the marmots is a cage containing hedgehogs), and (f) Hog badger (Arctonyx albogularis).
The most expensive wild mammal species sold for food was the marmot (Marmota himalayana) at over US$ 25 per kg, while raccoon dogs (Nyctereutes procyonoides) and badgers (Arctonyx albogularis and Meles leucurus) were priced at c. $ 15–20 per kg; hedgehogs retailed for as little as $ 2–3 each; all wild caught and intended as food. Squirrels (Callosciurus erythraeus and Sciurus vulgaris) were sold as pets for c. $ 25 each. The most expensive wild bird sold for food was the Indian peafowl (Pavo cristatus) at $ 56 each, while captive-bred crested myna birds (Acridotheres cristatellus), prized for imitating human speech, were sold as pets for c. $ 300. The Sharp-nosed pit viper (Deinagkistrodon acutus) was the most expensive reptile, at $ 70 per kg. For comparison, the average retail prices of pork, poultry and fish in Wuhan were $ 5.75, $ 4.25 and $ 2.32, respectively (source: Municipal Bureau of Commerce sw.wuhan.gov.cn/html/ztzl/sjfb/scyx/jgjczb/).
These traded species are capable of hosting a wide range of infectious zoonotic diseases or disease-baring parasites (see Supplementary Table S1 for a non-exhaustive summary of studies reporting diseases in these species in China since 2009).
Discussion
Our findings illustrate both the range and extent of wildlife exploitation in Wuhan markets, prior to new trading bans linked to the COVID-19 outbreak, along with the poor conditions under which these animals were kept prior to sale. Circumstantially, the absence of pangolins (and bats, not typically eaten in Central China; media footage generally depicts Indonesia) from our comprehensive survey data corroborates that pangolins are unlikely implicated as spill-over hosts in the COVID-19 outbreak. This is unsurprising because live pangolin trading has largely ceased in China13.
We should therefore not be complacent, because the original source of COVID-19 does not seem to have been established. This is doubly important because false attribution can lead to extreme and irresponsible animal persecution. For instance, civets were killed en masse following the SARS-CoV outbreak5, and any unwarranted vilification or persecution of pangolins and bats in relation to COVID-19 would risk undermining otherwise very successful efforts to better protect and conserve wildlife in China.
Regarding our insights into broader IWT issues in Wuhan, the animals sold were relatively expensive, representing luxury food items, not cheap bushmeat (Table 1). We thus make an ethical distinction here between the subsistence consumption of bush meat in poorer nations, versus the sort of cachet attached to wild animal consumption in parts of the developed world, notably China14, but also Japan15. While c. 30% of mammals were clearly wild-caught, indicated by trapping and shooting wounds, the captive breeding of other species is commonplace in China. Raccoon dog fur farming is legal in China; however, due to a drop in fur prices, raccoon dogs are now frequently sold off in live animal markets, augmented by wild-caught individuals. Similarly, all American mink (Neovison vison) originated from fur farms—noting that SARS-CoV-2 has been reported in mink farms in Europe and North America16, 17. In contrast, the captive breeding and sale of Siberian weasels (Mustela sibirica), is totally illegal in China, yet they are easy to breed, and sold openly, without attracting law enforcement. Indeed, prior to COVID-19 reforms, although enforcement officers from the Wuhan Forestry Bureau issued permits to market vendors, they were broadly disinterested in what species were sold. Furthermore, although animals were required to have an origin certificate and be quarantined to ensure they did not exhibit overt disease symptoms, no clear policy was enforced on these conditions. This is important because the species that were traded are capable of hosting a wide range of infectious zoonotic diseases or disease-baring parasites (Supplementary Table S1), aside from COVID-19. These range from potentially lethal viruses, for example, rabies, SFTS, H5N1, to common bacterial infections that, nevertheless, represent a risk to human health (e.g., Streptococcus). Indeed, globally, wildlife is thought to be the source of at least 70% of all emerging diseases18.
Legislative reform is also vital to clarify unequivocally which species are considered ‘wild’ and cannot be traded legally and safely. Another problem, as encountered by the WHO report is that, retrospectively, it proved difficult to ascertain which species were on sale, even to the genus level, relying solely on the responsible market authority's official sales records and disclosures1. As we19, 20, and others21, have proposed previously, China’s LFSSP and LESS must be updated to apply proper binomials, and to align with recent taxonomic revisions; for instance, cobra snakes (Nada atra) can be farmed legally for food with permits, but wild caught species, such as water snakes and wolf snakes were also sold in Wuhan, labelled simply as ‘snakes’. Such an application of clear species names would allow for more effective prosecutions19. Furthermore, the WHO reports that market authorities claimed all live and frozen animals sold in the Huanan market were acquired from farms officially licensed for breeding and quarantine, and as such no illegal wildlife trade was identified1. In reality, however, because China has no regulatory authority regulating animal trading conducted by small-scale vendors or individuals it is impossible to make this determination1, 21. Similar discrepancies concerning species identification and origins afflict investigations around the world22.
Another important animal trade that requires attention, outside of exploitation as food, is the supply of pets, like the squirrels and crested myna birds sold in Wuhan’s market. Our previous research found annual trade volumes equivalent to c. 17,000 parrots and c. 160,000 turtles (many turtles being invasive if escaping to the wild) sold online as pets via Taobao.com between 2016–2017, in contravention of China’s WACL and/or the Animal Epidemic Prevention Law23,24,25. While not currently the vector of any major viral epidemics, it would be naive to imagine that unconventional pets do not still also pose a serious concern for public health26. This potential for disease is likely exacerbated by poor sanitary and welfare conditions (Fig. 2).
Conclusion
Ultimately, changing the attitudes of consumers is crucial to reduce IWT in China. Efforts to stem the trade in charismatic species, such as elephants/ivory, rhino/horn, tiger bones, etc., have achieved modest success, and have garnered worldwide media attention and public concern27. Nevertheless, despite a general decrease in wildlife poaching and trafficking in China12, attempts to dissuade people from consuming lower-profile, but also higher-volume, species have still fallen-short. Crucially, efforts must be made to change the normative values of consumers through education, raising awareness not only for health, but also for animal welfare and global biodiversity concerns, else continued demand, despite recent national bans, may merely push suppliers into black-market and dark-web operations23. Our own previous investigation found that, in China, a substantial desire to purchase and/or own wildlife products as ‘prestige items’ still transcends social classes, age groups, education levels and rural versus urban residents, even though this involves breaking the law14. In major part this is because protective legislation has not been enforced consistently, fostering a nonchalant disregard for wildlife exploitation23.
President Xi Jinping has said that: the COVID-19 outbreak is a major test of China's system and capacity for governance, and we must sum up the experience and draw a lesson from it. In an early precautionary response to the COVID-19 crisis, on the 26th of January 2020, the Chinese government (State Administration for Market Regulation, Ministry of Agriculture and Rural Affairs and National Forestry and Grassland Administration) temporarily banned the sale of all wild animal and their products in markets, restaurants and over e-commerce, to least until the conclusion of the epidemic. Subsequently, on 24th Feb 2020, the Standing Committee of the National People’s Congress implemented a permanent ban on trading terrestrial wild (non-livestock) animals and consuming them as food. The Hubei provincial government announced on 11th April 2020 that the sale of live wild animals and poultry will be strictly prohibited as markets re-open in Wuhan. Ultimately China plans to invest c. $30 million to update Wuhan open-air markets to megamalls and inspire social capital. This is a major and commendable step, redressing previous tacit tolerance for many forms of wildlife trade in China, often already illegal under WACL and/or the CITES, which also carries a huge collateral benefit for global biodiversity and animal welfare28, 29. In response to the pandemic, on April 12th 2021 the WHO (co-signed by UNEP and OIE) released interim guidance for ‘Reducing public health risks associated with the sale of live animals on mammalian species in traditional food markets’30. Adopting these more responsible practices has the potential to save countless lives in the future.
