One of Wisconsin’s best-known sausage-makers has started building a 40-thousand square foot expansion that will produce a new product line. Ground was broken this week on the project at the Johnsonville Sausage headquarters near Sheboygan Falls. The company did not provide specifics on the new product line – but officials said it would use new technology to make food items that will be a key factor in the future growth of Johnsonville. The new addition will be connected to the company’s current processing operations – and it will make products for retailers and food service customers. Johnsonville expects the new facility to be up-and-running by the third quarter of next year, and it’s expected to create around 35 new jobs. The firm did not say how much the addition would cost.
