This was ~three weeks ago, so I'm a little surprised I couldn't already find anything about it on the forum. Maybe I'm just bad at searching?
Anyway, Ron DeSantis posted the following around the same time as the Florida ban:

I suspect the real motivations are more ordinary protectionism, but it seems like potentially a sign that cultivated meat might start getting politicized / embroiled in the broader culture war, though also (perhaps surprisingly) DeSantis has had supportive comments from a Democratic senator (see Vox again).
I'm interested in the extent to which alt-meat startups and policy folk were surprised by this move – whether this represents a more hostile environment than we expected, or whether this was "already priced in". I tried to look at stock prices, but based on some quick searches only found one publically-traded cultivated meat stock STKH, and don't understand enough about the process of when the bill's passing became inevitable to really interpret it.

I was surprised to learn from GFI's 2023 State of Global Policy report that "Uruguay, through a quiet amendment to a budget bill passed in October, banned the “importation, manufacture and commercialization” of cultivated meat for human consumption in the country for a period of five years".
My understanding is that Uruguay, Italy, Florida and Alabama now have cultivated meat bans, with Italy's held up by the EU. I believe the Uruguayan ban is the only one with a sunset clause.
