For example, five years ago Taipei City Health Department promoted a "Healthy Lunch Box"; it has now issued an "OK" certification for boxed lunches. To qualify to bid for school lunch contracts, vendors must meet health, safety, and nutrition standards. Once awarded a contract, they are subject to inspections and assessments.
以台北市為例，從 5 年前推動的「健康盒餐」到現在的盒餐 OK 標章，都是由衛生局出面，將符合衛生、安全、營養標準的業者加以認證、區隔，合格者才能參與投標，並須持續接受抽檢和評鑑。
