This was what I thought, but I may be wrong. Googling found no central storehouse of national and supermarket chain policies.
Looking at the biggest countries, as far as I can tell India has a 2001 ban on GM food still in place but has allowed GM cotton, but the anti-GM crowd there is afraid they may yet lose. We’ll see.
China allows GM with labeling. As labeling laws become enforced, companies there are switching to non-GM ingredients.
The situation in Europe seems hard to quickly pin down because spokespersons do not want to start a trade war with the US. They tend to refer to “moritoriums” rather than bans.
According to GM opponents, they have a lock on keeping it out of Africa with South America a mixed story. Australia and New Zealand allow it.
I was careful not to say that it did. On the other hand, I may be guilty of reading something into the column. errata is right. It does not clearly say that anyone has died because of excessive concern over DDT. However, I will certainly say that many people have died of malaria who would not have died if the cheapest effective insecticide for the purpose required, DDT, was sold to them. Probably it was bad strategy for me to bring up DDT, since this seems more certainly a losing cause than does GM.
As for this thread’s issue, government mandated labeling does threaten availability at food at lowest prices, and some people would starve, or die from poor nutrition, as a result. How many it is impossible to say now, just as it would be impossible to say afterwards.
