Bill Summary
Current law generally prohibits serving margarine as a substitute for table butter to students, patients, or inmates of a state institution. Current law also prohibits the serving of colored margarine at a public eating place as a substitute for table butter unless the margarine is ordered by the customer. Current law does not define “table butter.” A person who violates these prohibitions is subject to specified criminal penalties. This bill modifies these prohibitions so that they apply to “butter” rather than “table butter.” The bill also modifies the prohibition on serving margarine as a substitute for butter to students by expanding the prohibition to apply to students at public, private, and tribal schools, but also creates an exception for margarine that is ordered by the student or for the student by the student’s parent or guardian. In addition, the bill prohibits the use of margarine as a substitute for butter in meals prepared for service to students at public, private, and tribal schools, except when necessary for the health of a specific student as directed by the student’s health care provider. LRB-5383/1 ARG:skw 2025 - 2026 Legislature SENATE BILL 645
AI Summary
This bill modifies existing Wisconsin state law regarding the serving of margarine (also known as oleomargarine) as a substitute for butter in various settings. The bill removes the term "table" when referring to butter and expands restrictions on margarine use in schools. Specifically, the bill prohibits serving margarine as a substitute for butter at public eating places unless ordered by the customer, and prohibits serving margarine to students at public, private, and tribal schools unless it is ordered by the student or the student's parent/guardian. Additionally, the bill prohibits using margarine in meals prepared for students, with an exception for cases where a health care provider determines it is necessary for a specific student's health. The bill maintains existing provisions that allow margarine substitution for patients or inmates in state institutions when recommended by a physician. These changes aim to provide more specific guidelines about margarine usage in food service settings, with a particular focus on protecting student dietary choices and health needs. The act will take effect on the first day of the third month after its publication.
