Milwaukee Cottage Food Laws & Requirements

Wisconsin Residential Kitchen Operation (RKO) Requirements

Wisconsin's RKO law, administered by DATCP, allows certain non-potentially hazardous foods to be prepared in a home kitchen without a commercial license, including jams, baked goods, dried herbs, and candy. Operators must register with DATCP and maintain detailed records of ingredients, production dates, and sales. The law prohibits foods requiring refrigeration, foods with acidified or canned components (unless using approved methods), and products that require specialized processing like fermentation or curing. Home kitchen operators may sell directly to consumers but cannot distribute through retail stores, food service establishments, or online platforms that ship across state lines without federal approval.

Milwaukee Local Regulations & Additional Restrictions

Milwaukee's Department of Neighborhood Services enforces stricter standards than Wisconsin's state RKO law. The city requires home-based food businesses to obtain a food handler permit and pass inspection of the residential kitchen, including adequate handwashing facilities and separate preparation areas from household use. Milwaukee prohibits preparation of foods in home kitchens that Wisconsin allows under RKO, particularly products involving fermentation or shared equipment with non-food activities. Local health inspectors verify that home kitchens meet sanitation standards for residential use, and the city maintains authority to deny or revoke permits if violations occur. Direct sales must occur in Milwaukee unless additional permits are obtained.

Permitted Foods vs. Prohibited Items Under Milwaukee Rules

Foods permitted under Milwaukee's adaptation of RKO include non-potentially hazardous items: baked goods (bread, cookies, cakes without cream fillings), granola, dried tea blends, roasted nuts, peanut butter, and certain jams and preserves made with proper acid levels (pH 4.0 or below). Prohibited items include foods requiring refrigeration (hummus, yogurt-based products), canned vegetables without proper acidification, fermented foods like kimchi or sauerkraut, meat or seafood products, and anything involving shared preparation with household items. Panko Alerts monitors Milwaukee health department updates and DATCP notices to track permitted foods list changes, ensuring home-based operators stay compliant with current regulations.
