Boston FAQ
Are foam meat trays at Boston grocers covered?
Pre-packaged raw meat trays generally fall under federal labeling rules and are exempt, but in-store deli counters and prepared-food sections must use compliant non-polystyrene packaging.
Is foam cooler ice still allowed?
Yes. Boston's ordinance targets polystyrene foodware, not foam coolers or shipping packaging used for ice and frozen goods. Those items are out of scope but may be covered by future state action.
