Fiberglass Insulation in a New Oven

We just bought a new electric range/oven and were surprised to see that the fiberglass insulation in the back of the unit is not covered where the lightbulb enters the inside of the oven. Is this a hazard? I actually started to pull on the fiberglass, as it looked like packing material to keep the bulb from breaking in transit. Wasn't pleased when I realized what I was handling, and worried that our new stove might put the fiberglass in our cooking.
