Pigs are most commonly associated with eating not only their own feces, but those of other animals and humans. In parts of the third world, where villager dwellers excrete in the open, pigs are known to eat this excretia.

Pigs harbour a range of parasites and diseases that can be easily transmitted to humans. These include trichinosis, cysticercosis, and brucellosis. Very commonly, pigs are also known to host large concentrations of parasitic ascarid worms in their digestive tract. The presence of these diseases and parasites is one of the main reasons why pork meat should always be well cooked or cured before eating.
Bad effects of pork consumption
Pig's bodies contain many toxins, worms and latent diseases. Although some of these infestations are harbored in other animals, modern veterinarians say that pigs are far more predisposed to these illnesses than other animals. This could be because pigs like to scavenge and will eat any kind of food, including dead insects, worms, rotting carcasses, excreta (including their own), garbage, and other pigs.
Influenza (flu) is one of the most famous illnesses which pigs share with humans. This illness is harbored in the lungs of pigs during the summer months and tends to affect pigs and humans in the cooler months. Sausage contains bits of pigs' lungs, so those who eat pork sausage tend to suffer more during epidemics of influenza. Pig meat contains excessive quantities of histamine and imidazole compounds, which can lead to itching and inflammation; growth hormone, which promotes inflammation and growth; sulfur-containing mesenchymal mucus, which leads to swelling and deposits of mucus in tendons and cartilage, resulting in arthritis, rheumatism, etc. Sulfur helps cause firm human tendons and ligaments to be replaced by the pig's soft mesenchymal tissues, and degeneration of human cartilage. Eating pork can also lead to gallstones and obesity, probably due to its high cholesterol and saturated fat content. The pig is the main carrier of the taenia solium worm, which is found it its flesh. These tapeworms are found in human intestines with greater frequency in nations where pigs are eaten. This type of tapeworm can pass through the intestines and affect many other organs, and is incurable once it reaches beyond a certain stage. One in six people in the US and Canada has trichinosis from eating trichina worms, which are found in pork. Many people have no symptoms to warn them of this, and when they do, they resemble symptoms of many other illnesses. These worms are not noticed during meat inspections, nor does salting or smoking kill them. Few people cook the meat long enough to kill the trichinae. The rat (another scavenger) also harbors this disease. There are dozens of other worms, germs, diseases and bacteria which are commonly found in pigs, many of which are specific to the pig, or found in greater frequency in pigs.
