Medical science finds that there may be a high risk for various diseases as the pig is found to be a host for many parasites and potential diseases. Uncooked or untreated, the meat may contain harmful toxins, worms and latent diseases. Many of these infestations are harbored in other animals as well, such as mad cow disease in bovines and salmonella in chicken. The claim of the harmful uric acid in pigs, is now largely debunked as a myth by medical science.
Influenza (flu) is one of the most famous illnesses which pigs do share with humans. However, the origin of the illness is found in a number of animals besides pigs. It is harbored in the lungs of the animal during the summer months and can affect both the animal and humans.
Consuming excessive amounts of pork may lead to gallstones and obesity; due to its high cholesterol and saturated fat content. However, this goes for all sorts of animal flesh, and pork is in fact quite lean – leaner than most other domesticated animals – as long as its protective layer of fat is removed.
The pig is the carrier of various helminths, like roundworm, pinworm, hookworm, etc. One of the most dangerous and common is Taenia solium, a type of tapeworm. Tapeworms may transplant to human intestines as well by consuming untreated or uncooked meat from pigs or other animals. Many of these parasites, including the notorious trichina worms that causes trichinosis, are specific to the pig, or found in greater frequency in pigs, although most of them are also common in other livestock animals.
