不知道。問了一下Chatgpt

"At Costco, salad is washed in a commercial-grade salad spinner. The salad is placed in the spinner and then rinsed with cold water. The spinner is then spun to remove any dirt or debris. The salad is then drained and ready to be served."

跟Aprilmei說的一樣，估計各處都是這麽洗的。Costco的Spring Mix 號稱triple washed。 有人聲稱自己再手洗未必是好事。
