The Chishang Rice certification mark was implemented in 2005, and now around 80 % (475 farms totaling 1,200 hectares) of Chishang Township's 1,500 hectares of rice paddies qualify for Chishang Rice certification, having passed pesticide and quality tests. But some farmers among them have not joined, instead selling under their own brand names or via other sales channels; thus only about 50 % actually hold the Chishang Rice mark.
而「池上米」認證標章自 2005 年上路實行以來，目前池上鄉約 1,500 公頃的水稻面積中，已通過農藥及米質檢測、並具有提出池上米認證申請資格者約佔 8 成（475 戶，共 1,200 公頃），但其中有部分農家因有自製品牌與不同的銷售管道而未加入，因此實際持有池上米標章者，約佔 5 成。
