Plastic type in hydroponics grow containers not declared. What to do?

I have a serious concern. There are items like this sold on temu and amazon. I have personally purchased those for my DIY setup but just noticed that there is no number of the plastic indicating what type of plastic it is. Therefore, I can’t know if it is actually food safe and could be used to grow plants that are edible. Does anyone have experience/insights about this? These products are labeled for hydroponics without any label or information about the type of plastic! Should I throw them away?
