What happenened to them? I was at the store last night and looked for alternatives to Vlasic, and remembered this brand. They were hugely popular in the midwest and I know they used to be on the shelves here in Colorado, but not anymore.
I can’t find a website for them, and a google search took me to Dean Foods, and while they have several brands of pickles, Kosciuszkowy is not one of them.
Dean Foods happened. Over the years, they have purchased many pickle companies; they have gradually dropped the individual names, except in a few rare cases. Take Cates pickles, for example. Evidently, Dean’s is still packing pickles in Wisconsin under that label; the phone number is the same as that listed in NinetyWt’s link. (Aunt Jane and Dailey, among others, are also listed under that number and were originally owned by the Cates Pickle Company.) Cates was founded in Faison, NC in 1898; they were bought out by Dean Foods in the late '80s. The plant in Faison is still running, but with the Dean Foods name rather than Cates. And there isn’t a place in Faison where you can purchase a jar of Cates pickles.
