For example, before a public school can award a contract to a caterer, the meat, vegetables, and flavoring used in its meals have to meet Taiwan's Certified Agricultural Standards (CAS), Good Agricultural Practice (GAP), and Chinese National Standards (CNS) criteria. The health authorities must also receive regular health inspection reports of the school kitchens supplied by the company.
比如約定民營團膳承包商用的食材，必須是 CAS 認證的肉品、「吉園圃」蔬菜、CNS 調味品等；或須定期提供衛生單位檢驗的報告供學校查核。
