Expired food in Asian stores

A week ago I saw an Asian recipe on the Internet and suddenly I really wanted to cook it, so I went to a Chinese store to buy the necessary ingredients. After buying, I went home directly, but then, while chatting with a friend, I discovered that one of the products I bought was expired for six months! And the worst part is that I was exposed in the front of the counter. The store had a good attitude and in the end they reimbursed the money by transfer. Thinking good, I feel quite bad for this; If no one had mentioned it to me, would I have eaten that product without realizing it? What if something had happened to me? In addition, I noticed that the product packaging only had labels in Chinese, without English or Spanish. Doesn’t Spanish regulations require that food have tags in Spanish? 🥲🥲🥲
