Aren't there 3, at least? Dole, Chiquita, and Del Monte?

In the US, there's at least that many.

I've also bought Fyffes bananas [in the US] in recent times; those probably came from Aldi.

The more diverse ethnic marketplaces surely have other sources. They've got their own ways of doing stuff. :)
