I have just seen this open-access paper from
Nature looking at the animals for sale in the wet markets of Wuhan before the COVID-19 pandemic began.
Between May 2017 and May 2019, routine monthly surveys were being done of the wet markets to identify the source of the tick-borne Severe Fever with Thrombocytopenia Syndrome (SFTS), following a 2009-2010 outbreak with an unusually high mortality rate of 30%. This has allowed researchers to determine which species were present in the markets in the run-up to the COVID-19 outbreak. Notes were taken on the species being sold, whether they were from a wild source and whether they were being sold for food and/or pets.
Perhaps most notable in the results was that, of 36,295 wild animals recorded in the market, there were no pangolins or bats. A total of thirty-eight terrestrial wild animal species were found for sale in the market; it is considered unlikely that pangolins and bats were being concealed as other specially-protected species were found openly for sale. Of the thirty-eight species, eighteen were mammals - all but two (the Eurasian red and Pallas' squirrels) were being sold for food.
The mammals wild-caught for food (indicated by either wounds or reporting from the vendors) included the raccoon dog, Amur hedgehog, Siberian weasel, hog and Asian badgers, Chinese hare and wild boar. Those species being sold as food that were not reported as being wild-caught were the masked palm civet, Chinese bamboo rat, Malayan porcupine, Chinese muntjac, coypu, Himalayan marmot, red fox, American mink and complex-toothed flying squirrel.
There were also eight bird species and twelve reptile species found for sale in the markets.
