My personal theory is that the pork taboo may have emerged from this, with human greed being the catalyst. I.e. when pig farming became a business, people probably started feeding pigs with literal garbage instead of proper animal feed, to make as much profit as possible. Without science and without the equivalents mechanisms of FDA/USDA, inspecting the produced meat for suitability would probably be nearly impossible. This would eventually lead to a series of public health incidents, which would be straightforward to trace to pork. This would in turn led the clerics to label pork "unclean", in order to protect the public from such outbreaks. This was efficient since it doesn't need rigorous enforcement of the ban, and also would drive down the demand, thus the incentive to feed your pigs crap.
