Their advertising of it being like a sushi cut then makes this possibly dangerous marketing then, no?
It's not going to be possible to grow a thing that looks like a piece of salmon but is secretly riddled with viruses and bacteria.
Either the lab gets their sterile technique right and they wind up with something that looks like salmon, or they get it wrong and you wind up with bacteria slop. Things that look like salmon can only become so if no bacteria and viruses are present.
Don't forget that salmon and most other deep sea fish are immediately frozen when caught, which not only helps preserve flavor, but eliminates parasites (https://en.wikipedia.org/wiki/Diseases_and_parasites_in_salm...)
There's just such a gulf between the prices at which this is feasible for food use, and the prices at which existing large bioreactors can culture animal tissue.
If we can't even get plant slop ("algal biodiesel") culture consistent and cheap enough to burn in an engine, or get plant slop ("tilapia feedstock algae") cheap enough to industrialize to outcompete chickens... I don't know that I'm comfortable eating bioreactor meat that can only survive in the FDA danger zone.
In an a bioreactor where no immune system exists, there can't be a latent infection: there's no immune system! If it can infect and destroy what's growing, then it'll infect and destroy all of it. It isn't going to look like tuna meat after that.
