I just found a bug in my waffles???

In context i live in barcelona i went down to lidl to buy a waffle with chocolate package and some coffe, i went home i opened the package and eated one, after some minutes i started hearing some sounds inside the package, i looked inside and there was a big bug, like the size of a penny, black, and looked like a beetle or a roach, i dont have bugs in my house i live in the fourth floor so ive never seen bugs here except some flies or normal bugs like that, should i be concerned? Could there been bugs inside the waffle ive eaten? I still have the waffle package ive put it inside another plastic bag so it cant scape but i will preffer to not open that bag again🤣
