Worms inside my Cheese Curls packet

I'm eating my cheese curls straight from the packet. They're fresh and crispy. Sticking to my fingers. Some crumbs fall on my dress. I look down to brush them off, but notice they're moving! On closer inspection I see they are tiny white worms (larvae) and I've just eaten 1/4 of a large packet! How is that even possible to have things still alive inside a sealed packet? I wanted to vomit! I've taken a photo of the one worm that fell on the table and that I didn't kill. I certainly won't be buying another Willards item for myself, my kid or any kid for that matter. Hope won't cause any complication with my pregnancy.
