When we buy products at the grocery store we can look at the package and after the ingredients list it says "this product may contain traces of this or traces of that", or "this product was made in a factory that also process this or that". This is very common for traces of nuts and fish. I imagine all vegetarians have this routine for products they haven't bought before. Some vegans/vegetarians care about it a lot, some don't. Both are acceptable stances in my opinion. It's all about transparency. We also all know insects were likely crushed while harvesting plants and cereals we eat, and probably ended up in our food. But you do develop a certain disgust at the idea that a dead mammal/bird/fish was processed along with your food, so it makes the food less enjoyable. In this case, you would likely simply not go to Burger King, just like you wouldn't buy the pre-processed food that has traces amount of whatever you don't want to sponsor.
