I agree with this. It is super easy to prove and many of them are still alive too. Just put a random set of vegetables in a container and wait. You will see flies, aphids and all manor of other bugs born in it. I sometimes even find fruit-flies when I do this. Same with meats. Meats contain larvae and well, I won't gross people out here. That is why I cook what I can and wash everything with apple cider vinegar, since I have so much of it anyway. Also important to keep stomach acid strong for this reason. I envy Vulchers for their super strong stomach acid.
