If his statement was about the new samples altogether, then I'm afraid that's plainly wrong (as I will show below), and not a very promising sign for the potentially upcoming article of Gao. However it is not obvious from the literal quote what exactly he was referring to in that sentence.
The samples that were posted recently have animal DNA/RNA in the same single sample that is virus-positive. That's the news, as examined by an international team of researchers. There is nothing else that makes this worth talking about, that's the whole point, so better be clear about it. The samples that were posted previously didn't have that. In chinese pre-prints those were more associated with having been in the vicinity of human DNA (see below).
This is about February 2022, in Science, referring to Gao's team:
"The group reported last year that some of the samples that tested positive for SARS-CoV-2 also had human genetic material, but no DNA from other animals."
That's a completely different message isn't it? And with completely different conclusions by Gao's team.
For reference, this is a link to the pre-print of their article: Surveillance of SARS-CoV-2 in the environment and animal samples of the Huanan Seafood Market
However the news isn't about what George Gao has said. On the contrary. That is context for the story, the background on which this happened and continues. The Science article however is lot about that context, which is why I posted it. I was using the words "regarding the whole situation".
George Gao himself indeed hasn't said anything so far that makes this newsworthy. As far as we know. Except that it was apparently his team that posted the new samples.
