I ate turkey in Germany in the '80s already. It wasn’t super-common, but it was there. My family tended to have goose at Christmas dinners, but turkey was an option that was frequently used by others.

Wackypedia says:

• Turkeys are traditionally eaten as the main course of Thanksgiving dinner feasts in the United States and Canada, and at Christmas dinner feasts in much of the rest of the world (often as stuffed turkey).
• Turkey was eaten in as early as the 16th century in England.
• While the tradition of turkey at Christmas spread throughout Britain in the 17th century, among the working classes, it became common to serve goose, which remained the predominant roast until the Victorian era.

Here’s a turkey farming operation in Ampfing, Germany. That one operation slaughters and sells 3000 tons of turkey a year, apparently.

Turkey consumption per capita statistics show that Germany, for example, is about 3.4kg annually per capita vs. the USA’s 7.5, Hungary’s 9, and Israel’s (?!) 13.

Unfortunately statistics on this seem a bit incomplete. The first site lists 11 nations only. Over here they list 7, but barely have any overlap with the first site. More information gives some solid figures on the production and export of turkey meat. … And so on and so on and so on. So yes, turkeys are raised and consumed worldwide.
