The canines, named for their raccoon-like faces, are often bred for their fur and sold for meat in animal markets across China.
Ray Yip, an epidemiologist and founding member of the U.S. Centers for Disease Control office in China, said the findings are significant, even though they aren’t definitive.
“The market environmental sampling data published by China CDC is by far the strongest evidence to support animal origins,” Yip told the AP in an email. He was not connected to the new analysis.

WHO’s COVID-19 technical lead, Maria Van Kerkhove, cautioned that the analysis did not find the virus within any animal, nor did it find any hard evidence that any animals infected humans.
“What this does provide is clues to help us understand what may have happened,” she said. The international group also told WHO they found DNA from other animals as well as raccoon dogs in the samples from the seafood market, she added.
“There’s molecular evidence that animals were sold at Huanan market and that is new information,” Van Kerkhove said.
The coronavirus’ genetic code is strikingly similar to that of bat coronaviruses, and many scientists suspect COVID-19 jumped into humans either directly from a bat or via an intermediary animal like pangolins, ferrets or racoon dogs.
Efforts to determine the origins of the COVID-19 pandemic have been complicated by factors including the massive surge of human infections in the pandemic’s first two years and an increasingly bitter political dispute.
It took virus experts more than a dozen years to pinpoint the animal origin of SARS, a related virus.
Goldstein and his colleagues say their analysis is the first solid indication that there may have been wildlife infected with the coronavirus at the market. But it is also possible that humans brought the virus to the market and infected the raccoon dogs, or that infected humans simply happened to leave traces of the virus near the animals.
