Not to eat any type of insect, worm, or other invertebrate. This commandment refers to any insect not covered by commandments
-175,
-176,
-177, and
-178, and especially covers aquatic insects and worms. Jews are strictly bound by this commandment, while gentiles are not; but gentiles do earn extra reward from
G-d for choosing to follow this rule exactly as Jews must. A gentile would be wise to avoid the spiritually blemishing effects on ones soul from eating insects.
See commandment -176 regarding inspecting fruits and vegetables for insects.
This commandment also prohibits doing anything that is generally recognized as being disgusting, such as eating dirt or filth, using blood-stained tools to eat, or holding oneself back from using the restroom when needed.
