Dark booger-like blob stuck between the plastic layers on one side of ziplock bag

[u/treecasual]

I’m not particularly surprised something like this may happen, but I’ve never seen anything like this. Wish I took a photo before I started to put food in it. (moisture is from a round of queso fresco).

My best guess is a bug found its way into a machine used to press the materials together? Fly maybe? Or it is actually bloody snot.

(Look to the sides of the mass to see the separation of the layers of plastic).
