R3: Yes, and, No. During biblical times, there was no refrigeration, and cooking, could have been anything from a moment, to, charring. For instance, by Italian lore, you could not hunt or harvest swine, until you wear your cloak, three days in a row without removing it, and you stop harvesting swine, when you remove your cloak, three days in a row, when weather warms up. They knew cold air, was a key. Parasitic infestations. Bacteria buildup. Same as prior to refrigeration, vinegar, pickling solutions, were a primary means of food preservation. But then what? We find herbs. Medicinal combinations of herbs, ranging from garlic to salt, and so on. Predatory or carrion eating animals, today, we know that the visceral organs if consumed, can, in fact, be lethal. Cud animals, or grazers, are vegetarian and their internal organs are safe(r). Venison livers, I love. Swine livers, I am very cautious and pass. Ocean and freshwater dwelling fish and crustacea, it depends on the water quality. Cut along the top spine of fish to remove fat that holds contaminate waste, and wash with water. Shellfish, can filter out in clean water they live in, usually taking 24 hours to filter themselves. While the Bible, is a great “Owner’s Manual”, for humans, I believe they were trying to relate what they knew, in terms understood by themselves, at the period of time, it was written. Technology came into effect. In fact, the more science tries to disprove the Bible, the more it proves the Bible factual. Think about it. Science tells of bacterial infection, and pathogenic hazards. The Bible says, “Stay away from”, whatever food, because it is “unclean”.
