Virtually every vegetarian meal you've ever had was contaminated. My personal anecdote here is several years making pizza. Veggie pizzas are topped by hands that have handled meats without being washed, the pizza cutter used to slice your pizza just got done cutting a hundred meat pizzas. In my years making pizzas I made 2-3 pizzas in a non-contaminated way, it was a special request. Everyone is either unaware of this or is ok with it.
