Hi I Purchased Three Broccoli And Cheese Stuffed Chicken Breast

Hi i purchased three broccoli and cheese stuffed chicken breast yesterday. And cooked them as instructed. After taking a few bites i noticed a faint tainted sour taste and did not finish the rest my 14 year old daughter didn't finish hers either. Now this evening she has been complaining of stomach cramps and vomitting. I have experienced some cramping and diahrea. Is there a possibility we are experiencing food poison?
