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 are they killed by salting or smoking. Few people cook the meat long enough to kill the trichinae. 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.
Pigs are biologically similar to humans, and their meat is said to taste similar to human flesh.
Pigs have been used for dissection in biology labs due to the similarity between their organs and human organs. People with insulin-dependent diabetes usually inject themselves with pig insulin. Every creature was created by Allah for a purpose. The Prophet always encouraged being kind to animals. Although we should not eat the meat of the pig, it doesn't mean that we should hate pigs.
