About halakha when it forbids eating worms(tolaas) , what is this halakha, and how is it reflected in the question of fermented milks, (yakult and others) live lactobacilli, which medicine says are good for the intestinal flora, like Halakha see this?
Eating tolaim (bugs) only applies to bugs or insects that can be seen by the human eye. Bacteria and other microorganisms, that are too small for the human eye to see are not included in this prohibition and permitted to eat. As a side point, it is well known that the air contains hundreds of bacteria, and every time we breath in, we are breathing in all sort of living organisms. Therefore it is obvious, that the prohibition is only if it is possible for the human eye to see it.
