Pickle Bill

Wisconsin Governor Doyle signed the “Pickle Bill” (Assembly Bill 229) into law in February 2010. This new law, along with an emergency rule which clarifies points of the bill, exempts a person from having to obtain a license to sell home-canned fruits, pickles, salsa and other naturally acid and acidified products.  For more information about selling home canned foods go to:
