Study tracks China’s snake trade and flags conservation risks: full analysis

China’s legal snake trade is back in focus with a new Animals study examining trade records from 1975 through 2023 and concluding that medicinal and culinary traditions remain central drivers of demand. The paper positions China as a pivotal player in the global snake trade network, with trade patterns shaped not just by domestic consumption, but also by CITES controls and other regulatory shifts over time.

That framing fits with the longer arc of published research. A 2013 Oryx analysis found that China had shifted from a net exporter to a net importer for some snake species as domestic markets expanded, then saw marked declines in recorded imports and exports after 2004 following a mix of national restrictions and CITES-linked controls. That paper also notes China’s long-standing use of snakes for food and traditional medicine, the 2003 SARS-era ban on capture of terrestrial wild animals for food, and later regulation of snake use in traditional medicine.

Regional trade research adds more texture. A 2021 Frontiers in Ecology and Evolution review reported that between 1997 and 2016, China imported about 3.8 million live CITES-listed vertebrates and 1.4 million whole-organism equivalents from Southeast Asia, with the trade feeding five major industries: fashion, traditional Chinese medicine, food, pets and ornaments, and musical instruments. In that dataset, snake taxa including Ptyas mucosus and Naja ranked among the most imported live reptiles, and the authors warned that heavy reliance on wild and ranched sourcing creates opportunities for wild-caught animals to be laundered into legal supply chains.

That concern matters because the legal trade picture doesn’t capture the full risk landscape. The Oryx authors explicitly said they could not assess illegal snake trade because of its clandestine nature, even as they concluded that legal international flows had fallen sharply after 2004. More recent CITES background material also notes that at least 20 snake species in China have been exploited for food and traditional medicine, underscoring how broad the pressure can be beyond a handful of headline species.

Expert and industry reaction specific to the new paper was limited in public sources I could verify, but the wider literature is consistent on the main pressure points. A global 44-year analysis of CITES-listed snake trade in Biological Conservation found that snake trade can harm wild populations and create public health risks. Separately, a study of wild-caught snakes sold in Guangzhou and Shenzhen food markets reported severe Spirometra infection in market animals and warned that eating wild-caught snakes, especially when improperly prepared, poses meaningful human health risks.

Why it matters: For veterinarians, this is a wildlife health and One Health story. Even if most small-animal practices won’t directly treat traded snakes, the veterinary profession sits close to the consequences: disease surveillance, food safety, import controls, quarantine, animal welfare, and public communication around zoonotic risk. The trade also raises familiar questions about traceability. When legal, farmed, ranched, and wild-sourced animals move through the same commercial system, veterinary and regulatory oversight become more important, not less. (frontiersin.org)

There’s also a policy angle. Post-SARS controls, CITES oversight, and later wildlife-protection measures appear to have reduced some recorded legal trade, but recent commentary suggests China still faces tension between conservation goals and exemptions for economically important reptiles and amphibians in food systems. That means veterinary professionals following wildlife trade and biosecurity policy should view the new paper as part of a larger debate over how consumption traditions, farming systems, conservation, and public health can coexist, if they can at all. (cambridge.org)

What to watch: The next question is whether this study drives stronger calls for species-level traceability, better distinction between captive-bred and wild-sourced snakes in trade records, and more integrated oversight linking wildlife conservation, veterinary biosecurity, and food-market surveillance.
