Spar, The Orchards selling expired products!!!!!

I sent my sister to buy 3 1lt cartons of pure joy juice for my toddler flavored peach ×2 and orange on 10/11/2023... after I have served 1 and a half cartons to my 3 year old, I noticed foreign substance floating inside my son's sippy cup. I checked the expiration dates on the products and they state "BB07/11/2023" on both the peach flavored juices!!!! I don't know if I should rush my son to the emergency room or if I should wait for him to see if he'll get sick or not!? I am devastated!
