These eels were advertised on their website that 'chemicals such as antibiotics were hardly ever used,' and at the store, they were advertised as 'eels sold at CO-OP Sapporo are safe because these products are different from the eels picked up by the media.'
このウナギはweb上では「抗生物質などの薬品をほとんど使用していません」と宣伝され、店頭では「コープ札幌で取り扱っているうなぎは報道等で取り上げられているうなぎとは別の商品なので安全です」と広告されていた。
