Is this Kosher?

At the pool where I take my kids in the summer, there is a juice and smoothie stand. They are not under any kashrut supervision. They only use fresh fruits and milk, coconut milk, sugar, and honey with kashrut symbols and equipment such as knives and blenders that have never been used anywhere else. They are very nice and will openly show you how their operation works if you ask. Lots of Orthodox Jews come to this pool and say it’s kosher because there can’t possibly be anything wrong with it. What’s the scoop on that?

in leviticus 11:41, we are told, “and every swarming thing that swarms upon the earth is a detestable thing; it shall not be eaten.” any food known to be subject to insect infestation, therefore, cannot be eaten until the insects have been removed. so, there's a prohibition against eating insects. now, more and more processed food has added insects or part of insects in them — and you can read in the newspapers that we should eat insects, they claim insects being nuitricious. if i got the rabbis right we also should check food bevor preparing it. how do i avoid insects in my food — or is it allowed to eat food that contains a small amount of insects?
