I have been a Costco customer for years. First we had the dog jerky issue with them, selling Chinese-made chicken. Now I see the bag of broccoli in my freezer says "Product of China" on it. I told my wife to take it back.
I have traveled to Asia several times, including multiple trips to China. Based on what I saw, let's just say I don't have a lot of confidence in the quality of food products, nor do I of their safety. I will not knowingly eat foods from China. My experience is that the Chinese cut corners any way they can.
Costco, you will lose customers if you keep this up. I have no problem letting people know the origin of your products, especially those from China.
Do you do international travel? If so, how often, and have you been off the "beaten path" as I have? I have seen how Asian countries handle food products. This is why my suitcase is packed with foods when I go over. China is filled with "cancer" villages that are the result of rampant pollution problems, including excessive heavy metal exposure. Do you want to be eating #$%$ like that?
