Interesting point. But you also have to consider there are no faeces which contribute to infection risk in live animals and increase need for antibiotics. And we know a lot about keeping dead meat from going bad, see slaughterhouses and supermarkets. Can lab meat be grown under less favourable conditions for bacteria, eg cooling or oxygen poor?

Kind of.

Lab meat may be in a sterile environment, but it’s vulnerable to a lot more too. (As OP was saying)

Like an operating theatre is cleaner than a slaughterhouse, but that’s because the bar for what would cause contamination is that much lower.
