In the bible, pigs are listed in a general ban on a range of animals, not just the pig, but unlike many banned animals, they are explicitly mentioned.
“7 However, of those that chew the cud or that have a divided hoof you may not eat …. The pig is also unclean; although it has a divided hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses.”
There are also a few other references to pigs.
Many have suggested health reasons, and looking at pigs used in ancient times to clean garbage, makes sense and would explain why rats are included with pigs. The big problem here is that there was little difference in the health in a cow and a pig to eat in those times. Similar bugs are found in both.
Okay, what is so wrong with the pig? This is my theory.
During ww2, the allies put an embargo on Germany. Europe was an importer of food before ww2, so one big problem NAZI Germany faced was a massive food shortage. What happened as a result was a dramatic fall in pig production in the Reich. The reason was as pigs have physiological traits similar to humans. Pigs eat what humans do. It is much more efficient to make the food that people eat, then give it to pigs and then feed the pig to people. So the Reich cut back on pigs.
Now the writer of the bible would have known that too. He lived at a time when food was frequently short. Impoverished people were often close to starvation. A person raising pigs is denying many other people food. The pig farmer is competing with the needy people for food. The rich and powerful would eat, and the downtrodden would starve.
Conversely, cows, sheep, etc., feed on food that people do not eat, increasing the food supply.
He would feel this is wrong—better cows and sheep than pigs.
What are your thoughts on my theory?
