Johnsonville Sausage is a sausage company headquartered in Sheboygan Falls, Wisconsin.  Founded in 1945, it is one of the largest sausage producers in the United States  and the largest sausage brand by revenue in the United States.  Johnsonville sausage is available in more than 40 countries. Privately owned, the company has approximately 1,400 employees. 
In 1945, Ralph F. and Alice Stayer (original: Štajer) who were from Slovenia,[ citation needed] opened a butcher shop and named it after their hometown, Johnsonville, Wisconsin. The sausage made in their butcher shop came from an old family recipe, which originated in 19th-century Austria.  
Johnsonville Sausage produces a variety of sausage products, including: brats, grillers, Italian sausage, smoked-cooked links, breakfast sausage in fully cooked and fresh varieties, chicken sausage, meatballs and summer sausage. 
In 2014, Johnsonville Foods had the most sow slaughter capacity in the United States, with the facilities to slaughter 3,400 pigs daily. 
In 2013, Johnsonville Foods came under public pressure to stop using gestation crates. A Change.org petition asked the company to stop purchasing pork products from suppliers that confine breeding pigs to cages that restrict their ability to turn around during pregnancy. The petition was supported by The Humane League and acquired over 73,000 signatures. Two months later, Johnsonville Foods stated it would be working with its suppliers to move from gestation stall housing to alternative pregnant sow housing by 2025." 
In 2016, Johnsonville Foods became the title sponsor for the 2016 BaconFest Naples (www.BaconFestNaples.com) fundraising event in Naples, FL hosted by the Kiwanis Club of Pelican Bay (Naples, FL). The one day event draws 7000 people and is located at the Naples Municipal Airport South Terminal Lawn. 100% of the net proceeds from the event go toward helping end childhood hunger in Southwest Florida via the Kiwanis Club charity partners, St. Matthews House, Blessing in a Backpack and the Pan-Florida Challenge for Hungry Kids.
