Rainbow chicken disappointment

Bought in simply chicken ,chicken bites with bbq sauce , purchased this product on the 28th of March , decided to prepare it for my 3 year old child for lunch on the 4th of april and it's off .my house smells like something is decomposing . Imagine if gave this to my child to eat .due to the lockdown we have to be safe and fear this disease not fear off food which I trusted since I was growing up. Highly disappointed and angry
