I'm not sure why people would be interested to consume meat grown in a lab considering all the unknowns/risks.
Which ones? In general, most food-borne illnesses are a result of either faecal contamination, diseased animals, or poor post-production handling. 'Lab-grown' meat should be generally free of the first two. Obviously nothing's perfect, but it should in general be much easier to avoid contamination than in a slaughterhouse.
There is a risk of contamination in a lab as well and to be honest I don't understand why this kind of food is not subject to clinical trials. Some people(at least in the EU) try to avoid food resulted from livestock injected with hormones or other syntetic chemicals. Now you tell them to eat food grown(with hormones) in a lab.
I can't give you a good source on the subject so below is the first google result.
"most of the studies on safety are done or supported by the companies themselves.”
"It’s also long been known that breast cancer risk increases with higher lifetime exposure to estrogen. These facts have led many to question whether the continued use of synthetic estrogens in livestock is safe."
"The effects are very hard to study, experts say, because hormones are naturally present in both food and our bodies. Plus, the effects could be subtle and take years to show up."

Sure, but if it happens you can detect, determine what the problem was with the process, and fix it. With a slaughterhouse, you can reduce levels of contamination, certainly, but eliminating it is probably impractical; a certain risk is inherent to the process.

Right now, lab grown meat is effectively not commercially available, and being treated as a weird experimental thing. If it does become commercially available, it will presumably be subject to significant regulation.

Generally growth hormones for farm animals are _illegal_ in the EU. And you could reasonably expect similar rules to come in for any synthetic meat that might be available.
Just look at the chemical cocktail that's in any off- the- shelf "meat alternative" products. No way do I want that stuff in my body.
If Tesco, or any big retailer was honest about increasing sustainability, they'd be focusing on how to decentralize warehousing and shipping, and a simple solution is to support local farming. Unfortunately, the world doesn't operate this way, and we're stuck with this need to purchase food from far flung parts of the world.
We have a plethora of options available today that don’t require an animal dying or suffering and yet we still turn to mass killings to feed our desires. Humans really are at the bottom of the pyramid.
They are not only would rather think that it is better for a cow to die than to live some time, but also ..
..they would spread the idea that maybe humanity would better off going extinct..
And this idea genocidal idea can lead to things similar to what was done by different totalitarian streams of 20th century: Nazism, fascism, communism.
J.B.Peterson talks about this quite interestingly. But "woke" folks dont like him ;)
