Why Do Jews Not Eat Pork or Crab?

Why Do Jews Not Eat Pork or Crab?

On why pig and crab are not kosher foods



I was wondering, why can't Jews eat pork or crab?


In the Bible, G‑d lists two requirements for an animal to be kosher (fit to eat) for a Jew: Animals must chew their cud and have split hooves. Pigs do have split hooves but do not chew their cud, so we cannot eat pig meat and its derivatives. In the seafood department, we may only eat fish that have both fins and scales.

Here is a translation of the original Divine command, from Deuteronomy, Chapter 14:8-10:

And the pig, because it has a split hoof, but does not chew the cud; it is unclean for you. You shall neither eat of their flesh nor touch their carcass.

These you may eat of all that are in the waters; all that have fins and scales, you may eat.

But whatever does not have fins and scales, you shall not eat; it is unclean for you.

While the commandment to follow a kosher diet falls under the category of laws which do not necessarily seem logical,1 observing them only because G‑d commands us to,2 there are moral lessons we derive from them.

Here are several given:

  1. The birds and many of the mammals we do not eat are predators, while the permitted animals are not. We are commanded not to eat those animals possessive of a cruel nature, so that we should not absorb these qualities into ourselves.3
  2. The commandment refines the person and instills self-discipline.4

I hope this helps.

See Rashi Leviticus 18:4
G‑d's 613 commandments can be divided into three categories: mishpatim (judgments), chukim (decrees), or eidot (testimonials). The first category includes those observances which have an obvious reason, such as giving charity, not stealing or murdering, etc. The second category, chukim, includes laws which do not necessarily seem logical, and we observe them only because G‑d commands us to. The third category, eidot, includes those mitzvot that commemorate an event, such as Shabbat or Passover. Following a kosher diet falls under the category of chukim.
Midrash Rabbah, Genesis 44:1.

Thank you so much for providing a simple, succinct, and straightforward answer to a question that is bound to be asked hundreds of times per day on planet earth. The information about Halal food and the prescribed diet of Islam was very easy to find. On the other side of the coin, the facts about the prescribed Kosher diet of Judaism were fairly difficult to find. When I read that practitioner's of Islam do eat pork, granted that it is killed in accordance with the permissible/Halal fashion, I did make a quick, erroneous, assumption that Jewish people probably do consume pork, as long as it has been treated and blessed in accordance with the laws set forth in Deuteronomy. Again, I am assuming that the word Kosher comes from the set of rules that were set forth in Deuteronomy and neatly outlined by the author, Mr. Benjaminson. My words are much more labored than the author's, thanks again Mr. Benjaminson!!

Food poisoning
The idea that eating predators is the reasoning behind kosher law falls apart when you consider that nearly all fish are predators or scavengers. Food poisoning seems far more likely, since shellfish, pork, etc. are known to carry parasites and harmful bacteria, and food handling practices 4000+ years ago were less... refined.

While that may be the case, the fact is they are transgressing a Biblical commandment :(

I know many Jews who eat lobster the don't have fin or gills

Another reason for not eating predator animals is they taste terrible.

I am still trying to figure out why fish with no scales is unclean. We fish in pure mountain streams and catch and eat trout, which is scaleless. They do however, have fins.

Noachide law
Noachides (gentiles who honor the 7 Noachide Law in the Torah) are prohibited from eating any part of a living animal.
e.g. in some cultures sea creatures that are still alive are sold as a delicacy in restaurants (not that I ever felt like eating them).
Crabs and lobsters often have their legs ripped out while still alive too, so Noachides need to avoid them. This means we must how any animal is processed before the product is sold.

Pork is full of bacteria because pigs basically eat anything including garbage and other dead animals

re pigs and shrimp, etc
pigs are always associated with anything that is not right like, i.e you eat like a pig, you smell like a pig, more or less equating it with something that isnt nice in a human being. as for shrimp, lobster crab they are bottom feeders eating everthing that settles on the bottom of the ocean.

Shrimp, etc.
Anything that crawls on the bottom is considered dirty. I believe they eat excrement.

Hi! I hope someone can help me with this question: I was wondering because I want to follow the Torah regarding Dietary laws .So my family usually prepare foods with shrimp, crabs, and pork with noodles ; my question is can I still keep kosher if i get those out of my noodle, or the noodle as a whole is unclean .
