This is a major topic in itself. Its solution is our obedience to God does as God chooses.
Baha'u'llah in the Book of Laws has offered this;
"... God hath, likewise, as a bounty from His presence, abolished the concept of "uncleanness", whereby divers things and peoples have been held to be impure. He, of a certainty, is the Ever-Forgiving, the Most Generous. Verily, all created things were immersed in the sea of purification when, on that first day of Ridvan, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes.... " Baha'u'llah, The Kitab-i-Aqdas, p. 47
So as the eating of pork or meat is not forbidden, we can look for more guidance.
We can further discuss this if you are interested. There is much guidance in the Baha'i Writings about health and diet, which I see will guide medicine in the future. We may have to consider that nature provides the cures and we may be doing more harm than good by changing genetic structures.
