there was some plastic in my oven and I did not realize it..we cook some toasted ravioli and ate it last night. when I was using the oven again today I noticed this melted plastic in the bottom of the oven..there was some between the two oven racksplus a small pool on the bottom of the oven. Could the smoke / fumes from the plastic have gotten into the food we ate last night and it's something that be harmful
