if you do get pigs to create human organs, and if that does seem like an acceptable tradeoff, well, what do you do with the rest of the pig? Passing it on for food further increases the chance of giving a crossover pathogen a toehold, so you either assume that risk, or do some 'horribly inefficient' things, and deal with the risks of disposing of all that extra meat. Eeww.)

>Pigs and humans have identical digestive systems and already share most diseases and parasites. Diseases include parasitespseudorabies, swine brucellosis, tuberculosis, anthrax and tularemia.
In addition to pork meat, other by-products come from hogs. Pharmaceutical and medical by-products are second in importance only to pork meat itself. Hog by-products are a source for nearly forty drugs and pharmaceuticals. These pharmaceutical by-products include insulin for the regulation of diabetes; heart valves for human heart surgery; cortisone, epinephrine and skin for burn treatments and skin ulcers. The industrial byproducts are also important. These include suede for shoes and clothing and gelatin for many food and nonfood uses. Hog by-products are components of water filters, insulation, rubber, floor waxes, crayons, chalks, brushes, adhesives, fertilizers, upholstery, insecticides and linoleums.
