Campbell's Vegetarian Vegetable Soup: no longer Kosher:

Look sharp, you may still find a few cans of Campbell's Vegveg soup that has a Kosher symbol. According to Arlene Mathes-Scharf, Campbell used to produce the VegVeg soup (and possibly a few other soups?) at a separate Kosher plant, but they are now making the soup in all their plants, due to the increased cost of shipping.

Update: I can't be sure about this, but it looks like my queries to the Kashruth Alert web page and the Webbe Rebbe led to more alerts about Campbell Soup. This is really sad, especially since shipping costs must be pretty low at this moment.
