Salted duck eggs kept at room temperature dangerous?

I had ordered and imported cured salted duck egg yolks and they took 24 days to be delivered to me. Packaging is airtight but doubt it is vacuum sealed. No sign of mold, but are they basically filled with bacteria now and dangerous for consumption? Does boiling them for say half an hour kill all the bacteria and their toxins or will there still be a big risk?

Asked AI and they said possible bacteria include salmonella, e.coli, listeria and it's best to throw it out but I had purchased almost 200 of them and would like to salvage them if possible.

Here's what they look like.
