Plain-language change summary

The proposed changes to Assembly Bill 554 focus on how lab-grown meat products are sold and labeled in Wisconsin. The bill now requires that any packaged food containing lab-grown meat must clearly state "lab-grown meat" on the label in a prominent way and prohibits selling these products in public eating places or state institutions unless specifically ordered by a customer or under certain medical circumstances. Additionally, the penalties for violating these rules have been adjusted, now allowing for fines between $100 and $500 or a short jail sentence for first-time offenses. These changes aim to ensure transparency for consumers about what they are eating and maintain food safety standards in public facilities.
